We use a pi3b+ with a NodeRed app. We view the app on our club website. Currently, we monitor which of our 4 receivers are active, and show the elapsed time since the receiver went active. We have

<-- Hi Rod; check out "Node Red".? I set it up some time ago... it does require considerable time investment (but it's free!); it will run on a Pi; you will have to buy some I/O stuff (relay board,

Is anyone aware of a ham-priced friendly remote monitoring system? At work we installed a system from TASC Systems product called a Summit.? It provided analog voltage monitoring and alarm closure

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.

<-- Hi Ken; unless someone has intentionally limited the power output by turning down VR1 on the PA board.? I know you know that... but just in case the other fella' is finding the power output to

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

I am the kind of person who likes to test things myself so I know exactly what it says and what it's doing. And if someone would offer me a free DB 224 I would jump on it in a second! Chad Nelson

The G7 is a good performer but hates lightning...lost several in the 80s to Zap the lightning god...installed properly it can out do a DB224...opinions vary but I'm basing mine on 40 years of dealing

I was asked to go out the site in the attached picture yesterday to help troubleshoot. Before I go on, let me describe the site. Although there are numerous antennas on the tower, we are the only

Thanks i have changed the tx freq to 151.0 validated and rebooted? but still no transmit so I may have a hardware problem

Hey Jeff! Audio is tapped off of the discriminator in the Tait, ahead of all the filtering. Feeds a Palomar Telecom controller. The broadcast audio is then propagated out of all transmitters (420 and

I've gone as far as I can with this thing. I'm happy to pay someone to fix this thing. I'm totally blind and although I can check and align things with a service monitor, I can't replace parts. When
