Re: Spectra service menue

I finally figured it out. Just on a fluke I changed the 2 "time bomb" capacitors on the head and Bingo! It goes into the service mode every time even on the remote cable. I am not sure why, but I will take it! I had no other symptoms, and the VFD was bright and clear so I just assumed they...

I have a 900 Mhz 300 watt Nucleus paging transmitter that I would like to use on 927 Mhz repeater service. Do any of you have the pin out information for the power supplies? They were missing from the transmitter when I got it and I need to supply them from another source. I believe it needs +24, +1...

Re: Spectra service menu

Just out of curiosity, you might check the front panel settings in the RSS. From the MAIN MENU > F2 SERVICE > F8 SERVICE AIDS > FRONT PANEL AUTHORIZATION I checked that, the home button is not programmable. Only the top row and the keypad can be assigned. The home button beeps normally when pressed...

R-2001C HV power supply schematic

Do any of you have a copy of the schematic for the CRT high voltage power supply in a R-2001C Motorola service monitor? Mine has died and it needs some attention but I don't have a service manual for it.

Thanks,

PURC 5000 Help

I have a 300 watt 900 MHz PURC transmitter that has a problem. When I key it up it only puts out 90 watts and the full PA light briefly lights and then goes out. The drive seems normal so I assume there is something in the PA that is toast. It is a Model Q2934A and of course the service manual from ...

Re: Maxtrac Help

It turned out to be a Maxtrac 800 MHz LTR radio. I ended up blanking the board and installing conventional firmware and have converted it to a 902 MHz receiver. I was not sure about talkaround but it works fine and it has excellent sensitivity, I used up the last pair of 900 MHz filters I had and ap...

I have a 900 MHz Maxtrac that I can not read with any software I have including the Maxtrac Lab. It is a model M07UGQ6FU1AN with firmware version HLN9643D and a 16 pin accessory plug. Do any of you know what version of RSS will read and program this radio?

PURC5000 TX PL?

I picked up a PURC5000 to use on a 900 MHz repeater and I have a programming question. The model number is C85JLB-1106A and my question is, can it be programmed to transmit PL? I need to find someone with a suitcase programmer to help me out, but I have no idea about the TX PL.

Thanks,

Re: Help with R2001A repairs

I just checked it and it is not linear, using various hand held radios here are some of the results: If I transmit on 927.2 MHz the Spectrum analyzer says it is on 925.3 MHz a -1.9 MHz error. If I transmit on 445.0 Mhz the analyzer shows 448.2 MHz or a -3.2 MHz error. When I input 145.0 MHz the anal...
