Update on pd526: I tuned it on a recently calibrated r2670 and it tuned up nicely and easily. Less than an hour. Field tests show very little desense. Zero reflection on a bird 43 between tx and

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

Hi Mike, This may not apply to this site because no mention of AT&T, but perhaps our experience with very high noise floor to our 6M repeater that was located 600 ft away from a guyed cell tower might

I have a telewave 6 cavity duplexer, that into a dummy load has no desense. None. I am convinced that my 147 MHz RF is into the broad band amps, and they are doing a wonderful job of spitting it back.

This question could was easily answered by Google! The output power of a Kenwood TKR-850 repeater is adjusted through software programming, not a physical knob or switch on the unit itself. You'll

Agreed. I worked in avionics in the Air Force and if we were working a problem across several shifts, I rarely trusted the turnover I was given by the previous shift; I always validated what they¡¯d

I had asked them to put a dummy load on the top and sweep the line when they replaced the antenna (or at very least recheck the VSWR), but that didn¡¯t happen. I¡¯ll have to drag the spectrum

Can anyone tell me how to adjust the power output for high and or low power on a Kenwood TKR 850 repeater? I know there's a pot inside the repeater but can someone advise me on what it's labeled? Chad
