Sir, I have seen several MSR-2000 Power Amplifiers go spurious when the electrolytic capacitors dry out. Unless you looked at the output of the PA with a spectrum analyzer, I wouldn't rule it out.

Thanks for your advice I will take a look in there and setup what I need

Hi Rod, The SECARS club has what you are probably looking for.? Mark Noe, KE1IU, made up a telemetry system for our SECARS repeater site. He used a Raspberry Pi and it reports to

You really want to run the PA at or close to full power. They really do not like running at lower output. Go into the service mode in the RSS and run the PA initialization routine...you'll need a

I an using a 125w pa and I have the software setting to 25w is there any that I can increase the output to 30 -35w

You said there was desense with the tx power all the way to nothing. Was it the same level of desense using the iso-T and if so, then the problem is site noise floor. ?You have to track down the

I use an arduino nano. I monitor RF power, Voltage, PA current, temperature, and signal strength remotely. I use the talker library and it announces all that back to me via DTMF control. You have to

That has nothing to do with the desense. Sent: Sunday, May 11, 2025 10:25 PM To: [email protected] Subject: Re: [repeater-builder] Major Desense Replace the electrolytic capacitors on the PA
