Re: Why use a purpose built repeater box as a repeater rather than a transmitter, receiver, and controller tied (lashed) together?
Hi Frank and the group, About three years ago I put together a "Low Bucks" repeater (UHF), using two GE "MVS" radios. Kept each radio intact and used the option cable to all input/output to an NHRC-4

Re: Tuning procedure for Mobile Duplexer TFE6030A
A couple further thoughts. The factory TX and RX markings are from the perspective of a mobile that transmits in the 459 range and receives in the 454 range. Sweep it to see where it's currently

Hi folks, Just another note about using mobile radios in a repeater. Yes, their IFs were wide (stagger-tuned) to allow good function across the band coverage. However, since in single-frequency

Re: Tuning procedure for Mobile Duplexer TFE6030A
Based on pictures I found online, that appears to be out of a 1970's era Motorola car telephone.? There may be tuning instructions in the service manual but finding a 40+ year old manual could be a

Re: Clamp meter mistake -- watch for a balanced meter movement if analog
I worked in a very large industrial plant.? In my tool box was a couple of Fluke meters and the good old Simpson 260 and Amprobe analog meter.? I most often grabbed the analog meters for quick tests

Another basic digital voice question.
This is a project I've been keeping in the back of my mind for a few years. I want to take a mobile (in this case, an M1225) that the tx is no good (no power out), hook it to an MMDVM, and let the

Re: Clamp meter mistake -- watch for a balanced meter movement if analog
Way before everything became digital (because, as we've been brainwashed, digital is better), Amprobe was the leader in clamp-on ammeters. These all used analog D'Arsonval meter movements. Hopefully

Re: TPRD-1554 Troubleshooting
I worked on a TPRD-4544 many years ago that was not tuning properly. I had a feeling the coax used to form the coupling loop was somehow defective. I ended up buying two new coupling loop assemblies

Tuning procedure for Mobile Duplexer TFE6030A
I picked up a UHF mobile duplexer at a hamfest several years ago and now have a project I'd like to use it with. When I go to tune it though I find that it has some slugs that I don't know the purpose

Re: TPRD-1554 Troubleshooting
Jeff, Thanks for you comments and especially for the cable lengths. There was no evidence of arcing on the capacitor's body so I don't think it was damaged by a lightening strike. Do you have any idea

Re: Clamp meter mistake -- watch for a balanced meter movement if analog
Thanks, Mike for the clarification. I have not seen clamp meters with the mechanical movement; all the ones I've seen have a digi screen. But the former is good to watch for dips and spikes :)? Good

Re: Why use a purpose built repeater box as a repeater rather than a transmitter, receiver, and controller tied (lashed) together?
Peter, Be careful on those old radios you mentioned. While I built many "IC-20" repeaters in the '70s that was when we had 30 KHz spacing between slots and they worked well. Presently, that won't work
