I modded my vhf high power, high split pa, tricking the station into thinking it is a vhf 40 watt pa. Worked like a charm.

Ok, I am interested in making my range 2 cards report as range 1. I do not have the audio issue with my repeaters, but I found that I did have to retune the rx vco's slightly in order to achieve vco lock at my rx freq of 144.690. Can you provide the component numbers of the parts you are moving arou...

VE3TUH

I have a high split quantar that I needed to tune down to 144.690, rx. It wouldnt lock below about 144.790. The solution was to turn the tuning slug IN 1/2 turn on L2202, it locks now down to about 142.500.

Hi, just bumping this post, hoping somebody might have run across this. I have a W3 that has been bench tested/tuned, everything is 100% except for the W3 dtmf keypad modulation levels, they way overdeviate. I do not see any reference in cps to adjust the dtmf modulation level specifically, and ther...

VE3TUH

Yes I have, the radio is 100%, except for the dtmf generated by the keypad. For some reason, it is at the max level of allowed deviation. I figured I must be missing something here.

Randy

VE3TUH

Hi. How does one adjust the deviation of the keypad DTMF on a W3 radio? I see nowhere in RSS to do this, and see no pots on the W3 circuit board. the DTMF tones are max deviation, I need to set them down a bit.

Thanks very much,

Randy

Thanks everybody for responding. Scott, I did not want to take our business public, I simply wanted to know if anybody else has had trouble with Canadian postal money orders. I never mentioned your name in this post. It seems that your 20 to 25 dollar fee is a financial institution thing with your b...

VE3TUH

Hi everybody. Has anybody ever had any trouble with a US bank charging a fee to cash a Canadian postal money order? Or, on the other hand, has anybody ever recieved a Canadian postal money order and been able to cash it without a fee being charged? I am dealing with a person on the board now, he is ...

VE3TUH

Hi Thanks guys.
I have the e version. I must be behind the times though, I seem to be able to work better off paper.

Thanks again,

Randy

VE3TUH

Hi. Does anybody have a part number for an Astro Spectra, VHF, detailed service manual on paper. I would like to order one from Motorola, if it exists on paper. Thanks for your help!

Randy

VE3TUH

Hi. We have some w7 and w9 radios with badly scratched faceplates down at the firehall, I would like to replace them. Does anybody have the faceplate part numbers so I can order them from M?
Thanks,
Randy

VE3TUH

Hi. Can anybody help with the eprom? I need to update my t3020bx to a dx? If somebody is selling the dx eproms, let me know how much, thanks. Much appreciated, Randy

VE3TUH

Did you ever get what you needed, or do you still need it? Randy hello, I find myself in need of a cp for a full feature mt2k vhf that is compatible w/ r06.00.00. I have cp's for an a4 vhf, a5 800, and a7 uhf high split. My (new to me) mt2k is giving the "cp too new for this app." Any help would be ...

Hi Jason. Yes, a VHF range 2 A3 codeplug would be great. I have made the UHF codeplug work in an A3 radio, but the test freqs are not correct. Its a minor issue, but would be nice to have it perfect. I could send you the UHF A3 codeplug in return, if you like.

Randy

VE3TUH

Hi. Does anybody have an VHF A3 codeplug they would mind sending me?

Thanks,

Randy

VE3TUH

Hi Will. I suspected as much. All is 100 % except for the alignment frequencies in the RSS service menu. And yes, the radio does require a realignment now. Is there a chance that you could send me a VHF A3 codeplug? I would appreciate it, and thanks for replying.

Randy

VE3TUH

Hi all. I wonder if anyone could help me. I have a VHF A5 Spectra that I am changing to an A3. I have all the hardware sorted out, as in the head, connecting plate, and MLM. The MLM is out of a UHF, though. I changed the model number in the MLM to a VHF one, and the frequency range bits at location ...

VE3TUH

As KC7GR already posted above, just disable the option with RSS, Radio Service Software. If you dont have the software, you will have to buy it, or acquire it, or take the radios to a dealer with the RSS to disable the option for you. Its very simple, really.

Randy

VE3TUH

Yep, same here. I cant remember the exact reason, but you have to to attenuate your RX signal before the monitor will accuratly(?) decode the deviation. I think this is normal behaviour for this service monitor.

Randy

VE3TUH

As Will pointed out, if the radio is wired correctly, it will power up "on" if left in an "on" state. If both leads are wired to ign, then the radio will always power up in an "off" state, regardless of the state it was left in.

Randy

VE3TUH

How does mode names on an A3 work? As the A3 display is a 2 digit display, I do not understand how naming modes instead of numbering them would work.

Randy

VE3TUH

I have done this, your problem is the interconnecting board on the front of the radio. The A3 head requires a special board. The part number escapes me at the moment, but I have seen the remote connection board on ebay advertised as a HHCH interconnecting faceplate. Bought 3 of them myself.

Randy

VE3TUH

Well, that is an option.... where the heck is Will??? :D Another question is.... so if I did the RF swap and got nothing but more trouble, how about if I put the "good" logic board into the fail 01/90 radio? Same solution but different approach. Will that work? thanks! Depends on what is causing th...

VE3TUH

To reply to both of you, the RF board should be able to be swapped between radios, without error codes. However, the radio should be retuned afterwards. Also to both posts, my standard procedure with Spectra's is just to replace the electrolytics, on spec. It could eliminate some intermittent proble...

VE3TUH

Yep, I have. But not because I thought that I was going to change splits on a radio, rather because I accidently did the same as you, programmed a low split vhf with a high split codeplug. Ran into the same issues. Like I said above, that strip in the vco resonates best in a specific band, you canno...

VE3TUH

By cloning your high split codeplug into a low split radio, you caused the low split vco aux lines to toggle at the high split specs. This caused your low split vco to unlock at frequencies that it previously worked fine on. The aux 1 and 2 lines to the vco toggle at different frequencies depending ...

VE3TUH

I also had a great time. It was good meeting some of you, I picked up more goodies than I should have, and will be there again next year. CYA!

VE3TUH

Thanks, Cowthief, that was the info I was looking for.

Randy

VE3TUH

Well, I am still looking for some blister-pac cheapies that will do repeater, make/model if anybody knows, and who sells them.

Thanks,

Randy

VE3TUH

Hi All. I could be wrong, but it looks like the GMRS frequencies have been allocated in such a way as to allow for repeater operation. Does anybody know if that is true, and if so, has anybody seen any GMRS portables that will allow repeater operation? If so, I am interested in make/model. None of t...

VE3TUH

Thanks again, Will, that is a great tip.

Randy

VE3TUH

Hi Will. My board is a little different, HLN6345A. But looking at your pic, it looks like the jumper basically grounds the - side of the battery to a ground bus on the carrier board. Looking at my carrier board, this ground function is completed by the radio when the board is installed, but when the...

VE3TUH

Hi Will Can the location of the req'd jumper be described from the photo posted by Maxtrac300?

Randy

VE3TUH

How do you do that, Will? With a good battery on the carrier board, can you program the radio to retain the key with loss of power?

VE3TUH

One complication of modding the low split vco to range 2 is the vco steering lines. They will toggle at specific frequencies, (and I cant remember exactly what), and could drive your vco either in or out of lock. I played with this for awhile, and the end result was just not what I wanted. If you mo...

VE3TUH

The radio will do it, just turn it on in the programming.

Randy

VE3TUH

Thanks for the reply. At that number they gave me a part number to order the crt, 0180355A95, with a cdn price of $904.80. Ouch! Oh well. If anyone can get me one cheaper, let me know.

Randy

VE3TUH

Hi. Is there a workaround for a dim crt in a R2200B? Is there an internal adjustment to increase the range of the intensity pot? I understand that this may be a common fault with this equipment. Can these crt's be refurbished, or is a replacement available? It may not be the best monitor, but it has...

VE3TUH

You may be beat. The one thing the programming software verifies is the model number. Another codeplug would have to have the same model number, with the same "?", or the software will error out and tell you that the codeplug is from a different model pager. I could fix the model number in your code...

VE3TUH

Well then, you've got me. I've always understood the "S" to stand for Spectrum, and all the monitors I've seen have held true to that theory.

Randy

VE3TUH

equipped with a "S" Spectrum Analyzer, I believe.

Randy

VE3TUH

I would like to hear what you find, I have the exact same problem on one of my Spectra's, it can be a pain when scanning as the radio unsquelches very easily. Was wondering if as these radios age they will start to exibit common issues like this.

Thanks,

Randy

VE3TUH

Well, not only that, but when Clearnet started here around 15 years ago, they where using Johnson LTR radios, exclusively, I think. We sold and installed many. I think that they may have eventually loaded Motorola radios on their system too, but that was after I left Toronto, and I just didnt keep u...

VE3TUH

Thanks, Grem, that was kind of my thought on the first reply. However, I have heard of Clearnet, and yes, they operated in the 800 mhz band. My intention was to politely point out, that when asking for advice, it is usually good to provide as much detail as possible, as I for one have no idea about ...

VE3TUH

Sorry adam 12, I do not know nextel, or their freq allocations, or type of service, as you seem to. Thanks for pointing that out. Regardless, it is usually good advice to try and seperate rf sources, especially when having problems.

Randy

VE3TUH

You didnt specify what freq band this phone is on, or what type of service, analogue, digital, etc. However, if you are using the handset in the vehicle without an external antenna, it might be worth considering a car kit with an external antenna, to get the rf away from your equipment.

Randy

VE3TUH

Yes it can. You can copy and paste the configuration data, asuming you can find another MLM, same firmware, and you have an eprom programmer. I have made an adapter to allow addressing the chips without removal from the board. I dont know of any easier way to recover a faulty MLM, sorry.

Randy

VE3TUH

Hi Will. I have seen this when taking an MLM from a Spectra from 1 freq range and hacking it into a Spectra from another freq renge. I cant remember what the cure was, but that was the reason.

Randy

VE3TUH

I think you may have trouble going down to 440 with a 450 spectra. I have one also, and tried it, and was not real happy with the results. From what I recall, it had something to do with the pin voltages going to the vco, it would either rx but not tx well, or the other way around. Same luck with a ...

VE3TUH

You are going to be in trouble if you cant keep a Toshiba in good shape. In my experience they are tougher than the Panasonics.
