HI
In a very not good experience,,i blanked a Gm-300 with software Maxtrac Lab,after that of corse everything comes OFF in the radio. Second probleam,the codplug i readed from that radio was in a flopy disk,and it´s not readble anymore. The ticket with the serial number got scratches,and i can´t see the serial number too. I just know its a M33GMC00D2,and it´s very old,a 4 chanels only,and it wasn´t possibel to change that when i program with the RSS.That was why i start geting other ways,my thought was blank this one and program it than with the file from another GM-300 i have with 8 chanels! Just after that i saw it was a very stupid idea! I alredy saw in this forum something about this,think it must be change some codes in the codplug,can´t understand how to do it,and if it is aplicable in this situation,because i only have codeplugs from other radios,(have a codplug from one a radio like it too) If anyone can help is very apreciated.
Thanks.

From http://www.batlabs.com/:

Blanking/Recovering a GM300 Logic Board

At this time there is no GM300 Lab RSS that we are aware of that will allow you to blank and re-initialize a GM300 logic board.

The only tools that will let you blank the logic board are Maxtrac Lab RSS, and Emmco C++ Toolkit.

In order to recover the radio however, you need a codeplug from the radio that has been blanked, or a codeplug from an exact same model.

If you are using the Emmco C++ Toolkit, you can take the codeplug and dump it into the radio directly. You will then have to correct the serial number using the procedure above if you used a codeplug from another radio.

If you are using Maxtrac Lab RSS, I hope you like bit banging, because you are going to have to do some editing to get it back.

First, you need to gather some information.

+ Load the codeplug you are going to use to recover the radio into the GM300 RSS
+ Record the Model Number and Serial Number on a piece of paper
+ Go into the Help Menu (F1) and then into Other Help (F9)
+ Record the Panel Number and the Software Version on your piece of paper
+ Exit out of the RSS and load the .mdf file into Hex Workshop
+ Search for the Model Number you wrote down earlier
+ Locate and record the three bytes preceeding the model number (should start with 1Bh, 20h, 21h, or 29h)
+ You only need the first two bytes (ie. 1B02h for a M33GMC29C2)
+ Now you are ready to start the bit banging.

After you blank the logic board (Extended Codeplug/Clear Tuning Data), the codeplug is setup to be re-initialized by Maxtrac RSS. The GM300 codeplug structure is different.

First off, you need to go into the EEPROM Access feature (and turn on ASCII (F9)).

You will see that the codeplug is all FFh's except for the data in locations B613h through B61Ch. The 20h's are spaces and are the location where the serial number is stored in a Maxtrac. In a GM300, the serial number is stored in locations B600h through B609h.

Use the TAB key to get to location B613h. Fill locations B613h to B61Ch with FFh's. Use to get back to location B600h.

In locations B600h through B609h, enter the the serial number for the codeplug you are going to use (you can figure out the hex for each digit).

Update: Instead of putting in the actual serial number of the codeplug you are about to load, try filling locations B600h to B609h with 20h (space) instead. Once you do that, the GM300 RSS may recognize the board as being blank and allow you to dump whatever codeplug you like (use the RIGHT one!) into the radio without any further editing. If this does not work, then continue on with the rest of this procedure.

In location B60Ah, enter the panel number.

In locations B60Bh and B60Ch, enter the model index you got out of the .mdf file. NOTE: You have to enter the reverse of what you have written down. If your model is a 1B02h, you would enter 02h into location B60Bh and 1Bh into location B60Ch.

In location B60Dh, enter the software version.

Select Write RAM (F8) to dump the data into the radio.

Now, you still need to figure out the checksum and enter it into location B611h. Use the procedure above in Codeplug Hacking to figure out what you need to enter for the checksum. Once you have figured out the checksum, stick it into location B611h, and Write RAM.

You are now ready for the big test. Fire up the GM300 RSS and load your codeplug. Try writing it to the radio. If you did everything correctly, then you should get a good beep out of the radio when it resets. If not, you're on your own, I don't know what you did wrong.

A couple of issues you need to be aware of. First, if you used a codeplug from a different radio in order to get the blanked one back to life, you need to go through the serial number changing procedure to get it back to what it should be (on the sticker for the radio). Second, since the radio was blanked, all the tuning and calibration data was cleared. The radio needs to be retuned by a radio shop to get it calibrated/aligned so that it operated within specifications.

There you go, that's how to recover a blanked GM300 series radio. Unfortunately it isn't as easy as a Maxtrac, but the procedure does work.

We have tried hacking around a bit in a blank codeplug to see if there was any way to get the GM300 RSS to allow a blank board re-initialization, but have not had any luck. So, that is the reason that you need a codeplug to get some important setup data from.

Please do not try to make a radio something it is not. You MUST use a codeplug from an EXACT model of the radio you are trying to recover. You cannot make a UHF into a VHF model, a high power into a low power radio, an masked codeplug into an expanded codeplug radio, or anything else silly like that. It WILL NOT work.

Hope this helps.

Hello :
If im not mistaken i believe it was wavetar that did some experimenting with GM300 bds and found out that by changing a string of info in the GM300 that it would make the radio believe it was a factory blanked bd.
By doing this it allowed you to reinitiate with the actual GM300 program as a GM300 again.
This way you didnt need a code plug but could select the model needed per your logic bds and radios specs.
Do a search for wavetar as the author and or reinitiate gm300 ect.
Im sure youll find the info hiding here some place.

Many thanks for help me. I m a litle confiuse about using Hex Editors,,,but after reading this,i think there´s one probleam,,i do not have the Serial Number,,i only know the mode,and yes i do have a DBF file from an exaclty model like this. I m Portuguese soo i have some dificulty to understand all the technical terms , but i´ll try.
Thanks

Posted: **Tue Oct 28, 2008 12:55 pm**

The serial number is not critical. Just use your name or some combination of letters/numbers that works. Or make it the infamous "123ABC1234".

Posted: **Tue Oct 28, 2008 2:43 pm**

I did indeed post about how to re-initialize GM300's. Elmano, forget about using a hex editor and codeplugs. Simply use the Maxtrac LAB "EEPROM ACCESS" feature to make some small changes to the board after you blank it with the LAB, as per the instructions in the following thread:

http://batboard.batlabs.com/viewtopic.p ... initialize

Depending on your computer screen resolution, the numbers may not line-up properly, but the top string of 20 numbers from 600 to 60F are the address locations in the GM300, and the 20 numbers in the bottom string are the values you need to change each corresponding address to. The LAB makes them all "FF"...you need to make them 20 20 20 20 20 20 20 20 20 20 FF FF 1B FF FF 4F. Once you make these changes, you should be able to use the regular GM300 software to re-initialize the radio as the desired model in the service alignment screens.

Thank you all very mutch

finaly i done it! it was very simple in did,using the acess to the eeprom in the maxtrac lab and your instrotions was simple has you know .
I did injected the codplug from the other model i have,now they have the same serial number,i think! if i want to change that its just doing it with an Hex program,,rite?
Many thanks,if wavetar doesn´t say .."use the eeprom acess.." i´ll never be hable to understand at all,,it was like in the movie.."..Luke use the Force..."..

Thanks again

Glad to hear you finally got things working. You should have been given the option to manually enter the serial number during the board initialization process. Oh well, you can always blank it and try it again!

Posted: **Wed Oct 29, 2008 5:20 pm**

Ok,,soo you mean after making all the process again,when i load from the disk the codplug,before program it to the radio,i´ll be able to change the serial number?,,is that rite? !

Posted: **Thu Oct 30, 2008 1:10 am**

What software do i use for it ?...normal RSS doesn´t have that function to change it (i think),,and with Maxlab i think the software doesn´t reconize the DBF´s from the normal RSS !,,mabe is in the EEprom,,,but i need to know what numbers is!
Thanks

Posted: **Thu Oct 30, 2008 10:06 am**

Once the board is blank, you go into the Service menu (F2) in RSS, and do the logic board replacement procedure in the RSS.

Posted: **Thu Oct 30, 2008 12:41 pm**

Thanks for the help.
But i think that way can´t work,,because if i do that,than he doesn´t acept the codplug from the other radio!,,Mabe i need to change the codplug befoure inject it in the Radio.
After blank i tryed what you said,and than start geting herrors to program the codplug,,and asking to balnk again!.
Thanks

Posted: **Fri Oct 31, 2008 5:28 am**

Hello :
If read and understand what you have done - Im thinking you have the radio working but are now attempting to change the serial number .
To do this you could reblank the gm300 logic bd again .
This will erase the bds serial number in it now.
Then go back to your normal GM300 program and reinitiate the now blanked logic bd.
During the process you will be given the screen to enter the serial number you want.
Make sure it matches the code plugs serial number you have that you want dumped into the radio .
After the reinitiation is done you can now dump the code plug you have into the radio if you wanted the programming info put in as well.
But remember that you dont need the saved code plug now if you were only attempting to change the serial number.
You already did that during the initiation of the logic bd .
Also if you did the changes in the eeprom as wavetar has provided info on then consider the logic bd blanked and go through the GM300 rss programs replace logic bd and reinitiate the bd as needed.
It too will give you the option to enter the serial number as the bd is telling the GM300 program its blanked and needs reinitiated.
Also when you reinitiate the logic bd = you must intiate it per the radios specs.
You can not initiate it as another model its not put together as.

Thank you for your time,,i apreciate.
The point is don´t need to change the serial after blank,,because when you put the codplug,the radio catch the serial from that codplug!,,,soo,change befoure,using the serial from the codplug i´ll inject it´s not need,,like i said the codplug alredy have it.
Soo ,,changing serial after blank in RSS,of corse doesn´t acept other codplug with another serial!
The probleam is i don´t know the serial from this radio,and to let it with this serial from this codplug i have to inject ma be a probleam in my country for authorities inspections,because this codplug is from another radio i have!Same model.
The radio after Wavetar and otheres here help,is working very good!,,just need to change the Serial .

I tried this operation and couldn't get the radio to initialize past block 5 of 20. It runs into "Serial Bus Error" and I have to blank the board and start over, but it never actually gets there.

Any help?

Posted: **Fri Dec 18, 2009 11:52 pm**

Hello:
Serial bus error usualy means a comunications error from the computer to radio as i recall.
If you blanked the radio and the error ocurs id be suspicious of the logic bd being bad in one way or another.
A serial bus error is diferent from radio not supported as say a newer version of the GM300 rss was used so the older would no longer work but since you blanked the radio it shouldnt have an issue with any version of GM300.
I would how ever try the newest version of GM300 rss to see if it by chance would solve your problem as a last resort to be sure.
From your statement of it programs block 5 and back but fails from block 5 forward to 20 indicates to me the radio computer are indeed comunicating otherwise it woulkdnt have program 1 through 5 blocks - so im in the belief you have a bad logic bd that causes the block 6 forward to fail coms popping up the serial bus error .
Out of couriousity= What made you want to blank the radio ???
Had a problem that you was hoping to cure by blanking and reinitiate by chance ????

I couldn't read the radio. It kept coming up with checksum issues and bad codeplug alarms and stuff like that. Someone had obviously been dicking around with this radio as it was given to me by one of our customers with no control head, a blown fuse, and a corrupt codeplug. It was in such bad shape they didn't even want it back.

Turns out the issue I was having was that this particular radio has a masked logic board with no external EEPROM.

Seems with the GM300 RSS all I can tell it to be is an 8CH 12.5kHz radio. There are no options when initializing the board to turn it back into what it really is.

Factory model number is M34GMC20D3AA, but no version of GM300 RSS I have has that as a selectable model number.

Seems to be working the way I have it initialized, but sure would like to get it back to what it's supposed to be.

Hi , sure about the late, but if i understand you want to Blank a GM 300 board, and want to use the RSS for it, cant, must use Maxtraclab , theres the option for it, then use the RSS to inject a code plug from a GM 300 (same) model,, to do it.

Posted: **Mon Sep 21, 2015 3:46 pm**

To Admin/Mod Staff
I think this would fall into this Thread, my apologies if it doesn’t .

I have a Radius M120, 2 channel VHF .
I want to swap the logic board out of it and replace it with one from a
GM300 UHF 16 channel. (Modified code plug, I have the modified code plug.)

(The VHF radio and it’s now UHF logic board, will now become a later project, probably resolved using which-ever procedure we end up from below)

Logic Board, from VHF radio: HLN9074D

(Also, I’ll swap the front plastic.)

Software Tools available :

RADIUS GM300 RSS, (legally)
GM300/GR300/GR500/M10/M120/M130 HVN 8177F VERSION R05.00.00

Hex Workshop v6.7 (6.8.0.5419/ Sep 1 2014) (also legal)

The RADIUS/GM300 RSS software, I can use pretty well.

I have not used Hex Workshop (just bought a newer version) in about 10 years, have to Re-learn it and would need step by step instructions, like the ones in d119’s post of by d119 » Mon Oct 27, 2008

I do not have Emmco C++ Toolkit or Maxtrac Lab RSS.

Can I use his instructions, more or less ?

Is there a more applicable “step-by-step” available?

I will keep looking around on the “Bat Board” but, just want a reality check on what I am trying to do, and it’s be a few years since I done any “Bit Banging”

Hello pete01:
The way I read your post indicates to me you want to make a VHF into a UHF .
Ok yes blanking the logic bd or swapping it with a UHF GM300 UHF logic bd is one way to do this.
However you will need to change out the rf bd to a UHF rf bd and no you cant blank and reinitialize the rf vhf bd to make it a uhf rf bd.
The radiated frequency bd is component specific and it would require major component changes to do and not even close to being feasible to do.
Another thing is the m120 is a two ch front control face and you will need a multi ch control face from a gm300 to do it right.
The m120 bd will have a control number in the reinitiation that tells the radio what type of radio front control the logic bd needs to work with or youll get an error .
So you can do the logic bd but need to change to the correct rf bd for the uhf band and cant use a vhf rf bd in a uhf radio.
Satelite

Posted: **Mon Sep 21, 2015 6:00 pm**

Thanks for your reply.
I am not making it into a UHF, it is presently VHF and want to leave it that way. I want to only take another logic board from a UHF and put it into the VHF radio. Need to address the Logic Board and make it usable in the VHF band. I do not want to do anything to the RF board,if I don't have to, no service monitor here. Yes, change the front to a GM300.
Again Thanks.

Posted: **Tue Sep 22, 2015 12:45 am**

Hello pete01:
When you change out a logic bd you do need to calibrate it to the rf bd.
There will be a dc voltage measured at the logic bd that needs to be entered to match the new bd to the rf bd to be able to enter freqs to the bds talking to each other.
Also you do need to calibrate several transmit freqs to assure they are on center of freqeucy for accurate on freq .
Wattage output will need to be adjusted to match the bds together as well.
This is all needed since you now have a different logic bd that needs to shall we say get to know a new friend to be able to tx and rx correctly otherwise expect poor irritating performance.
So you will need an accurate volt meter/service monitor /and wattage meter at the very least to get it done correctly.
I may have a situation that may benefit both of us but give me your answers to these qestions and lets see if I don't have what you want.
Im always looking for gm300 uhf radios in 16ch so ?????
What gm300 model for specs are you looking to end up with ?
How many channels ? Which wattage output and would a 25 watter be ok if I don't have a 45 watter ?
Do you want wide band 25 kHz for ham or do you need a 12.5 kHz narrow band for todays legal freqs ?
What is your intention for use when done ? - Not looking to see if right or wrong but more whether the end use is what you actualy need.
What exactly is your GM300 UHF radios model number and is it working correctly ?
When you say you have a modified code plug for the gm300 uhf logic bd - do you mean the logic bd has a modified code plug and if so what is the modification to the uhf logic bd ?
Is there a reason for doing the logic bd change - like ones not working or are you just looking to get more channels ?
It might be best if we just trade radios and youd get a multi ch gm300 vhf mobile that's setup and calibrated correctly rather than hex editing to make it vhf or reinitiating to vhf since you lack the service equipment to do it.
I can always use a good functioning gm300 uhf logic bd or complete functioning uhf radio.
You pay shipping of yours to me and pay my shipping back to you which if I recall is aprox 15 dollars flat rate at the usps one way so 30 dollars total.
You will be much better of spending 30 dollars to have this done right otherwise youll just screw yourself into the ground.
But if your h bent on doing it the hard way

then plan on hex editing bit banging to get the logic bd to think its blanked per wavetars above info and reinitiate with normal gm300 rss but youll need the service monitor / watt meter / volt meter and then be able to properly do the reinitiation procedure and recalibrate the logic bd to rf bd.
I do have a generic step by step reintiation info sheet which tells you what the control panel number is to match yhe logic bd up with the front plastic your changing out if you try this method.
A m120 2 ch logic bd will not match with a gm300 multi ch front control till you change that control panel number in the logic bd to say what its communicating with for functions available from the front plastic control.
Hope I didn't further confuse you but rather further educated you on whats needed to get this done right.

I didn’t expect, this is a good possibility.

I will copy/paste you questions and answer them that way.

Questions/Answers:

What gm300 model for specs are you looking to end up with?

Similar to GM300 M33GMC29C1AA or Radius M216

How many channels ?

Looking for VHF 16 channels,

Which wattage output and would a 25 watter be ok if I don't have a 45 watter ?

Yes.

Do you want wide band 25 kHz for ham or do you need a 12.5 kHz narrow band for todays legal freqs ?

Amateur use only, 25 khz

What is your intention for use when done ?

The Amateur Club, that I belong to, recently purchased repeater equipment from an existing repeater site, took out these radios, and put in a Yaesu “Fusion” repeater. The Treasurer of the club has asked me to check-out the Radius M120s and see if we, the club, could use them for “Loaner Radios” (start a radio library) for new Hams in our club that presently can not afford or do not have a radio.

I have conferred we the Treasurer of the club and informed him, but I did not get into the fine details, (into the weeds) in which you have discussed :

Copy of my e mail to him to follow:

The two radios are presently 2 channel versions.
> RF boards (PA) are 45 watt versions,
>
> One is set high at 59 Watts, was used as the receiver, thank goodness, and
should be lowered.
> The other, the transmitter, was set reasonably at 35 Watts.
>
> I was able to read them with the RSS (Radio Service Software) and downloaded
the data.
>
> I removed them from the enclosure, disconnected the controller, replaced the
Accessory Connectors with the normal, (I believe) and since then verified that
the Accessory Connectors should be pins 15 & 16 jumped, for internal speaker use
but now cannot read with the RSS !!-Can’t explain this except that maybe the pin
out of the Accessory Connectors was modified by the software and I did not
realize it.
>
> Have tried different methods of “Reading” the radios, ie.. using different
“Code Plugs” from my library of “Code Plugs”.
>
> “Code Plugs” are what gets modified to alter the radio say from 8 channels to
16 channels.
>
> And you need this “Modified Code Plug” to be able to “Read” the radio.
>
> My library does not contain any 2 channel to whatever number channels mods,
hence, no joy.
>
> Not all is lost though, a common modification of these two channel “Radius
120” models, actually internally just about identical to the “GM300” , except in
the number of channels, is to replace the face of the radio (2 channel) with a
true GM300 front one, multiple channel display, and also replace the “LOGIC
BOARD”.
>
> The “LOGIC BOARD” is what presently can not be read.
> I would replace the logic board with one I have and have the “Modified Code
Plug”.
>
> They, the radios would then be cable of 16 channels vice 2.
>
> I think I should proceed, what we have now is not of much good to anyone.

END OF EMAIL

I knew I would have to find someone with a service monitor, we have club member that works for a Local Commercial Motorola outfit but, he is busy, and the wait would be long and I would not be doing the adjustments, and that may be time consuming and really a lot to ask of someone.

But, not being to read them has me concerned. I willing to use personal radios to get two working VHF 16 channels for the club and mess around the RADIUS M120 later.

(Maybe some day, Santa will bring me a service monitor, if I ask Him… (Her)… nicely, but that’s a topic all it’s self !!)

*******************

What exactly is your GM300 UHF radios model number and is it working correctly ?

GM300 M44GMC20D3AA (UHF) Two of them, from my own stock pile.

Unless you want to talk about some RADIUS M216, some with modified code plug , I think, it’s been awhile since I took inventory but apx 5, I would have to go through them and confirm modified or not, but believe they all work. .TBD.

When you say you have a modified code plug for the gm300 uhf logic bd - do you mean the logic bd has a modified code plug and if so what is the modification to the uhf logic bd ?

8 (or less) to 16 channels (UHF) bit banged (hacked) code plug

Is there a reason for doing the logic bd change - like ones not working or are you just looking to get more channels ?

More channels.

Hello pete01:
My first thought of why you may not be able to read with rss is that possibly you put in a newer code plug that was read with a newer rss version by using an older rss version.
And you might have done that and if so heres why you now cant read the radio with your rss version.
Now im assuming the radio is still working no error tones on power up but just the normal one time short single beep which indicates a good self check was passed and ok.
Now if a radio was read and programmed with an older rss version but then later read and programmed with a newer rss version then automaticly the radio can not be read with the older versions of rss and would need the newer version or newer than the last it was programmed with.
Ok it is possible you used an older version the radio was last programed with but you used the older version rss to blow in the code plug from another radio with same specs but it was read with the newer rss version than your now newer code plugs version and if so its still a good radio just needs the newer rss version to read and match the code plug you just modified and put in the radio.
Also at one time the m120 rss and gm300 rss were completely different rss programs but m later did combine the M10/M120/M130/GM300 into one rss version to read program all the radio types.
Ok your GM300s are 8ch masked uhf 438 to 470 MHz splits.
I do have GM300 VHF splits if youd be interested in trade for yours ?

Satelite,

The RADIUS (VHF) M120s (Clubs) I did not put in a modified Code Plug.

I took them out of the enclosure, with controller still connected,
Read them with RSS GM300/GR300/M120/M10/M130 R05.00.00
DATED 01-OCT-94

Printed out the MODE CONFIGURATION (FULL) (for both M120s),
disconnected the controller, put in an accessory connecter, with pins 15 & 16 jumped (for internal speaker). Then read them again with the RSS, now, no beeps and ERROR 58 Radio Code Plug Error. Tried different modified Code Plugs (to read only, no pushing), (GM300.MDF files) no joy.

That’s when I thought to swap out the Logic Board with the UHF radios, that’s where I am with those two now.

I am willing to work on that issue but, after I can work a complete radio swap (UHF for VHF), want to take care of the clubs needs, get them 2 VHF 16 channel radios.

I would be look for:

HLD4321B 136-162 Mhz
or
HLD4322C 144-174 Mhz

Unless it cam be done during the same shipment, if it comes to that, so yes, I need advice on the RADIUS (VHF) M120s, to make a comprehensive decision. Can I deal with the problem with what I have available and/or do I risk just making a bad situation worst?

The radios I swap will be working, I will double check them.

Do you want a one to one swap ? or something else ? I am flexible here.

Thanks for your input and offer to assist in this situation, it is greatly appreciated.

Hello Pete01:
Correct error 58 is a bad code plug and most of the time a bad data string that messed up the final check sum.
Ok I think I got you at you have a bad logic bd due to error 58 and you have not blanked the original logic bd and its still as was but error 58.
And im hoping that's the case because you can recover from that error 58 code by cloning in a good reading of a code plug that is exactly the same model number which will correct a corrupted code plug plug.
Its not tricky but you let it confirm the good radios model number and after it does you right now don't be slow but rather quickly plug the programmer cable into the waiting powered up non working error 58 mobiles mike jack and let the clone option push the good working code plug into the bad code plug thus replacing the bad with a known good matching code plug it originaly had.
Then just check calibration etc to make sure its good.
Many times it will be because the corrupted portion of the code plug was replaced with good and didn't touch the calibration settings but youll need to verify that was the case.
Im looking at a 0ne to one swap not even going to cheat you with a 1 for 2 - were friends here

You just pay shipping to and return and ill make sure you have proper working wide band vhf mobiles in return.
I can use uhf wide banders here more than I can the vhf models so your actualy doing me a favor too while solving your issues.
My radios will be the 144 to 174 MHz split.
One option you havent mentioned and I think I have a few too is a maxtrac 25 kHz wide band in multi channel operation.
I may have a couple id need to look but they will fall right in line with what your needing for specs too and my opinion is they are easier to deal with in most repairs but a gm300 is a good rid too.
Im wondering if when you read the vhf m120s WITH THE CONTROLLER CONNECTED that the rss saw the controller in the option port and didn't know how to handle the info it received and hard locked the code plug at that location for data and couldn't proceed then when you couldn't go further you unhooked powered down and left code plug with bad info and cant return to start of data string for a read programming session.
Just thinking in left field here but if the code plug some how got stopped during programming then you BRICKED as they call it the radio.
At one time that was considered fatal but not so much with now days experience.
Just my opinion.

Hello Pete01:
Forgot to answer one of your qeustions.
I don't think youll make it any worse by trying to recover the code plug as its already messed up.
If you have a pc and correct rss and a known good exact copy of the same model number then yes you may be able to recover the radios code plug but then you lack the service monitor to check to see if in fact its still on freq and calibration.
But never hurts to try and if you do succeed you ganed valuable experience as well.

Hello Satelite,

You asked wondering about vhf m120s WITH THE CONTROLLER CONNECTED..

I was thinking of hooking everything back to the original config, controller connected, and see what the RSS reads, I do that.
No Joy, still Code Plug Error 58.

I do not have a good plug code for a RADIUS M120 M43GMC20A2AA

Maxtrac for the Freq split, I could be interesred.
How do we go about this one to one swap, via PM ?

Hello pete01
I sent a pm with info on my contact to you.
Also I have the code plug you need to retrieve your m43 M120 mobile.
Cant email it but can mail it on a 3.5 diskette.
My old computer for the older m radios has a 3.5 diskette drive bay but my much newer computer does not have a 3.5 diskette drive bay and has the newer cd drive bays so I cant get the code plug over into my new computer from the 3.5 diskette to email it to you.
And if I could youd need to be able to get it back onto your older computer to use it.
Hopefully you used a true DOS computer 25 MHz clock speed or at least not too fast so you didn't have issues.
But ill mention as many in the past have said at one time or another.
Do not do or risk corrupting the radios code plug- Bricked
Do not use extremely high clock speeds as if too fast it can send the program data so fast the radio can not accept it and drops data bits into the wrong code plug slots due to out of timing ability for the code plug and if it does error 58 can occur.
Motorola recommends TRUE DOS computers at 25 MHz clock speed but I do know for a fact many have had good luck at 50 and even 75 MHz clock speeds.
So no windows plat forms were recommended even when running an emulated dos platform with slo mo programs to slow the computers clock speed down.
Not saying it didn't work here and there but wasn't a stable programming platform with too many failures leading to corrupted code plugs.
Many have including myself used windows 98 but booted into true dos mode and that platform did work for me without any issues if you made sure the clock speed didn't over run the radios code plug.
My opinion and just my opinion is don't run faster that 50 MHz but idealy 25 MHz clock speed is best and 75 MHz does seem to work but I feel your tempting fate at that high speed but if you read and saved a good code plug for that model then what the hey go for it as you have a good code plug to save the radio if and I say if you can get the code plug into the radio and I say that because you still might have issues due to too fast clock speeds and will need the good code plug programmed back into the radio at a slower clock speed to correct the error.
If that happens to be the case then youll need the slower type dos 25 MHz clock speed computer or the program slo mo to slow your too fast computer to get it done and save the radio.
Just as info be aware that you CAN NOT bricked a radio by reading it with a too fast computer and that the code plug gets corrupted only during a programming session back to the radio and its now you don't want too fast or the computer blipping off but back on due to power or rib or programming connections or power to the radio getting disrupted etc as these will mess up the programming and cause errors.
But as stated if you saved a good code plug reading from the radio then went to programming with issues youd have the save your @$$ good code plug

Hello Satelite,
Thanks for the advice concerning DOS and such. I am using Old Computers (Laptop and desk top), not sure of the clock speed but, pretty sure, without looking, they are 286 processors.

Here is what I have for trade, all or any combination.

Three (3) GM300s: M44GMC20D3AA,

Five (5) RADIUS: D44LRA7PA5BK,
5 pin accessory connector, missing connectors

I’ll check your PM after I am done with some chores, prior to a practice SET this morning.
Later,
Regards,
Pete01

Hello Satelite,
Did you get my test PM?

Posted: **Mon Sep 28, 2015 6:47 pm**

Hello pete01:
No pm in my box so no didn't get anything.
I sent a message to you with my personal contact info awhile back too.
Did you get it ?
I do have a few VHF radios but looks like you have more than I do in vhf to trade .
You have 8 to trade and id say I have 3 mutli ch vhf to trade but I do have at least 6 of the motorpla vhf 2 ch mobiles.
I can blank and convert some of those into multi ch vhf rigs but they would have a trunking front on them but still work.
Or if your interested I do have two SM50 high power VHF rigs but only two ch mobiles not multi jobs.
Or I do have several VHF M1225 mobiles some the 20 ch and some 4 ch jobs but they will also do narrow band or wide band so they are usable yet today in the new nb freqs.
But im not opposed to trading the vhf 1225 mobiles for your mobiles but probably not one for one but maybe three of yours for two of my 1225 vhf mobiles due to my m1225s being usable in todays n/b freqs.

Hello Satelite.

I got something in my PM inbox, now…I just do not know. Try sending again please.

I am OK with a 3-UHF GM300s for 2-VHF M1225 20 channel
Would you want to work out something with UHF RADIUS M120s for VHF M1225 ?

This is getting to a point we need to get PM working.

-Pete01

Posted: **Wed Sep 30, 2015 5:48 pm**

Hello Pete01:
Not too keen on the M120 mobiles.
To be honest I had a fair amount of issues with the m120 mobiles that seemed like they had a batch of bad oscillator crystals that failed much more than any gm300 or maxtrac.
The few 120s I had out with customers were not well liked and not so dependable when compared to a maxtrac as an example.
Might just be coincidence but thats the opinion I and my customers developed.
Im fine with 3 radius mobile d models which is a 8 ch uhf for a m1225 vhf if that helps any.
I can use a few ut not say 9 but ill work with you on some vhf 1225s or id do better if youd be ok with 2ch maxtracs in the vhf as in id give you two of those for one multi 8 ch gm300 or radius multi ch.
What ever works best for you.

Hello Satelite.

3 UHF RADIUS: D44LRA7PA5BK models, for One VHF 1225 model.
Can I get them for 20 channels ?

1 UHF GM300: M44GMC20D3AA model, for 2ch VHF Maxtrac.
Can I get them for 20 channels ?

The 20 channel thing, is it something I could do or should you do it ?
How would that change a deal?

No matter what, I would like to end up with at least 2, 20 channel VHF for the Club.

I can do with 2 channels radio(s) but would prefer 20 channels.

FYI:
The UHF GM300: M44GMC20D3AA models that I have, have a modified Code Plug.
I have 3.5 floppy with the modified Code Plug and can make a copy of the original Code Plug.
I do not believe I got around to modifying the UHF RADIUS: D44LRA7PA5BK models. Will check them all out before shipping.

Hello Pet01:
The 2ch maxtracs to my knowledge can not do 20ch but you can get 16 ch if you have the right 5 pin logic bd which these do.
However youd need to change out the 2ch front to a multi ch front.
Blank reinitiate and recalibrate the radio.
Now if you put in a hln9313 16 pin logic bd and a 5.34 eprom then you can get 32 ch with scan from front panel after reinitiation and calibration.
I can do it but id need to rob 16ch bds from usable radios and multi ch fronts would be off of 800 meg trunking radios so wouldn't say scan on windows decal etc.
I can burn the 5.34 proms as I have a prom reader/burner.
I was mentioning the 2ch maxtracs in case youd be able to use them as is but id probably redo them as 16ch but the scan function would be selected on front but when you lift mike off hook it comes out of scan and when mike put back on mike hanger clip the scan will not come back until you select scan again and this is different from the 16 pin logic bd as it will automaticly go back to scanning on mike hang up if already in scan.
And if I did a 2ch to 16ch then it would be the multi ch front off of a trunking radio that's labeled different but works exactly the same as a conventional rig but different window decal.
I know I have several m1225 4 ch rigs but thinking there were a few 20 ch rigs too.
Ill check on that and get back to you.

Hello Satelite,

I am OK with my 3-UHF GM300s M44GMC20D3AA, 16 Channels
(They have modified code plugs)

16 CH UHF GM300s M44GMC20D3AA, 25 WATTS: RADIO_1
16 CH UHF GM300s M44GMC20D3AA, 29 WATTS: RADIO_2
*9 CH UHF GM300s M44GMC20D3AA, 28 WATTS: RADIO_3
*Do not know, or remember why 9 CH not 16

for your 2-VHF M1225 (20 or 16) channel units.

I do not want to have you jump through hoops to make it happen, if you do find you have some 20 channel ones, all set up, that even better,

Here is what I have left to work with:

4 CH UHF RADIUS D44LRA7PA5BK, 31 WATTS: RADIO_4
2 CH UHF RADIUS D44LRA7PA5BK, 30 WATTS: RADIO_5
2 CH UHF RADIUS D44LRA7PA5BK, 32 WATTS: RADIO_6
2 CH UHF RADIUS D44LRA7PA5BK, TAG MISSING ERR0R 58: RADIO_7
2 CH UHF RADIUS D44LRA7PA5BK, ERR0R 58: RADIO_8

I got one other RADIUS D44LRA7PA5BK, hold off offering that one, unless it is required, still interested in any of the above ?

It's late, better go.

Hello Pete01:
Heres what I have:
2ct SM50 VHF 45watt 2ch
3ct M1225 VHF 25watt 4ch
3ct M1225 VHF 45watt 20ch (will do 24ch if you number ch rather than name it.)
6ct Maxtrac VHF 25watt 2ch
Also im sure the rig I used to use in the camper to yack at the ranchers is a maxtrac 16ch VHF 45 watt rig and he is up for grabs as ill need to place a narrow bander in now to yack with them when on the prairie dog hunting.
Just a few mentions here on the Radius D44LRA7PA5BK mobiles - these are the 35 watt 16 ch m214 or m216 series mobiles .
The reason your probably seeing the 2 and 4 ch in them is no one setup anymore ch so windows shows only those in the radio.
If you add up to 16ch total it should now show those as well.
Error 58 says code plug error which doesn't necessarily mean the code plugs toast but most likely wrong info or someone forced a non compatible bit of info into the radio.
I would be interested in trade on those as well but would want some wiggle room just in case it is a bad logic bd and repair them here myself.
You can not read program the Radius mobiles you have with maxtrac rss because the Radius M214/M216 line uses radmbl rss to read program.
The m1225 mobile also uses the m1225 rss which was available from Motorola as either dos or windows so need correct rss for dos or windows which ever computer platform your using.
Also another thing is the Maxtracs Radius and GM300 all use the same mounting bracket where as the M1225 uses a diferent type so wouldn't fit each other .
Are you needing to trade brackets now too ?
Pm me you phone number and lets talk this one out as to exactly what youd like to do and speed things up plus leave less clutter on the main bd.
Thanx Satelite
