Curious, after replacing the chip did you build a new codeplug and try to load it or did you think a blank chip would already have a codeplug on it?

mogman

Thanks, I don't suppose there is a list (value etc.) of suspect caps so one can have them in hand.

mogman

I am getting a deviation meter fail during self test, it appears to be reading deviation fairly accurately even with the failure.
I am assuming this is a recap situation and wondered which board I should start with.
Thanks!

mogman

I see a codeplug forum but there are no posts there so other than "go to supersite" so I will try here. I am looking for Srecords and/or codeplugs for the MCS2000 J split high power Mod II and Mod III radios. M01JLM9PW6AN and M01JLN9PW6AN. I have been to the Supersite with no happiness. Th...

Never got a chance, the last time I booted the machine the correct filters showed up, not sure why, maybe during initialization it detected them??
Any who all is well now........fingers crossed...

mogman

I am trying to re program the filter options in my 120B
Using the commands given by Wowbanger I continue to get syntax errors, example.
cal:eeprom:ifbw0 "300"
I have tried many different ways but have failed, the syntax error is in the ifbw0 portion of the command.
Thanks

mogman

Wowbagger, I sent you a PM but for some reason it sits in my outbox instead of the sent box, did you receive a PM from me?

mogman

Does anyone know the kit number to add battery revert to the Quantar? (one with cable and temp. probe) are they still available?
THANKS!!

mogman

Thanks, don't think my little XTS would put out the 20-40W needed to drive it, I assume it is to be used with the factory XTVA amp.

mogman

Thanks for the info, I am looking on fleabay and see several "VHF" MTVA control units for pretty cheap, of course there are also many 2M "bricks" out there that should do the job. So I do not have a specific part number to list.

mogman

Can a MTVA "control unit" be used on a XTVA (STX3K) ???
I have a complete 800MHz unit but would like to use it on VHF, looks like I can use it without the amp, but.........

mogman

Thanks, I was just curious, got a short stack of these recently, they are running 5.6 so at least they are not too far behind, will probably do whatever is needed of them.

mogman

I am curious, did the MCS have an upgrade "kit" like the Waris series, also can the same flash adapter be used to put it into programming mode? if so where can I find the pin-out for the RIB to accessory cable?

mogman

OK, that makes perfect sense, Thanks

mogman

Just curious, if the I and the N DSP are the "same" why is there an I and a N?

mogman

Sneaky SOBs the RX lower limit was 935.0125, put in 925.000 so all is good now.

mogman

I have done this before for VHF and UHF but I am sitting here staring at the hex editor and drawing a blank. I need to hex edit the Astro 25 CPS R20.01.00 for 900MHz amateur frequencies. Does anyone know what the band edges are?? I can find say 450mhz ($80-74-D2-1A) for example but not 940-935-896 e...

mogman

Well to answer my own question, I assumed it was a VHF because of the D in the part#, installed it in an R2 VHF Quantar and she made 125W no sweat, did not get rejected by the codeplug so it is obviously a R2 VHF PA, can add that number to the list...

mogman

I am trying to ID a Quantar PA TLD1295A searched everywhere with out luck

mogman

PM me if you cannot locate the Consolette interconnect board and ribbon cable.

mogman

I need the part# for the XTL5K mid power dash W head ribbon cable, again search turned up nothing.

THANKS!!!

mogman

Thanks

mogman

If you want to get RX audio it is on pin 24-25 of the D25 acc. connector, if the radio powers up with the control head plugged directly into the drawer unit without jumping 20-22 there is a problem, you will not be able to control radio power using the on/off button on the control head with 20-22 ju...

mogman

Sorry for the double post, I just posted above (I DID do a search without any hits, the search feature is not very good)
See above for the steps I have taken, looks like an RF board issue, I have a dozen of these on the bench right now.

mogman

Try connecting the control head directly to the drawer unit, then jump 20-22 on the acc (other D25 connector) this will power the radio up, this will eliminate any issues with your home-brew cable. You are connecting the control cable to the left (just under the high power DC connection) D25 connect...

mogman

I have a growing pile of model I VHF XTS3000 radios that have a peculiar issue, as soon as they are turned on they give a busy channel indication and will not receive no matter how much RF is pumped into them. I am cloning a test code plug that I have been using for some time, the number that fail t...

mogman

Yes, but is the 1.5K and 5K bridge the same part#?

mogman

Thanks, what I think I was trying to ask is if the ribbon is the same with the MX and 05 heads, so I think you did IIRC
I forgot to ask if the bridges are the same???
Thanks

mogman

Does the XTL1500 non W head dash radio use the same ribbon cable (HKN6192B) as the XTL5000 non W head?
THANKS

mogman

Thanks, that is what I have read also, I am only charging XTSxxxx radios.

mogman

I get a flashing red light when I try to upgrade my Impres gang charger (no display) from V3.4 to V3.11 I have had no issues with the single Impres chargers and have done quite a few, tried it on several of the bays with no luck. Also the V3.4 is OK for LI-ION yes?? If so not a big deal but read som...

mogman

I assume that it is the "software download ID"?

mogman

Thanks, I wonder if anyone has that file?

mogman

Thanks guys!!!

mogman

I was always led to believe there was an ID chip on the Quantar backplane, I have looked two over pretty closely and cannot see anything accept a three legged transistor looking device marked U1 ???
Is there a way to read the backplane ID? I do not remember ever running across it in the CPS.

mogman

If you have a Motorola PS that fan will run 24-7 If the radio is not booting correctly due to a problem with the SCM the PA fans can run continuously.
Go to the meter page and check on what the thermistor voltage is, normally around 3.5V fans will start to run around 2.0 to 2.3V

mogman

I am curious, I have been told the Quantro "PA" that is in the same shelf is nothing but a path for the exciter to get to the outboard IPA, makes sense. Now the question, is that "PA" that is connected to the exciter frequency dependent? Second question, is the IPA and PA in the ...

mogman

Does anyone know how to adjust the contrast on the W3 PLUS radio, the procedure for the Astro Spectra Digital radio does not work, only CHAN and RF options toggle using the top side button after entering service mode.

mogman

This looks like the mating connector, in case anyone in interested.
Housing AMP 102387-1
Contact AMP 6-87756-8

mogman

Thanks, that should give me enough info to go on!!
Boy AMP makes allot of connectors, I have a pretty good pile of Centracom "junk" might find one there.
Also I found what looks like the identical chassis connector AMP part# 104338-1so finding the mate should be easy.

mogman

I am looking for information on the mating connector for the peripheral tray interface jack on the Quantar, it is the connector "J" OR #27 on the back of the unit, it is a dual row 10 pin connector.

mogman

I am thinking of adding an external watt meter to one of my 900MHz Quantars, I have the TLF6890B external module that has RCA type connectors. So the question is can I simply wire the module directly to the Quantar external watt meter module outputs to the "peripheral tray interface" refer...

mogman

Probably not the issue considering you changed the SCM but are you running an ATMEL codeplug chip? if not that can cause issues.

mogman

As it turns out the thermistor bias resistor was wrong from the factory on all of the PAs from this production run (of the 6 I have anyway) Well they may not have been wrong if the factory wanted to cook the crap out of the PAs before the fans came on. R4119 in the PA temperature circuit is listed o...

mogman

Anyone know how to adjust the local mic gain on the MTR2K? I am using a GMN6147B mic which is supposed to be correct, but the audio is too "hot" it is not over deviating the transmitter, it just has too much gain.
The repeated audio is great!

mogman

Keyed the 900MHz unit and the fans started after only 3-4 min, before I could even detect much temperature change on the front of the PA.
When I can get back to it I am going to try another SCM, but I have other fish to fry.

mogman

Just powered up one of my 900MHz units and the PA fans did not run.

mogman

No but I can't remember ever seeing the PA fans run on startup.

mogman

I am bench testing a VHF Quantar and cannot get the PA fans to run, swapped PAs did the power alignment (was very close BTW) and still I can get the 300W Motorola dummy load pretty damn hot and the PA gets uncomfortably warm on the front of the amp. I thought the fan control and alarm (no entry in t...

mogman

First I have never seen a notch cavity with two ports, not saying they don't exist but I have seen allot of cans and never a two port notch, second I swept it from DC to daylight, it is for SURE a pass can
