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

Then my guess is, it actually IS a high split transmitter and the VCO is not locking as low as you'd like it to (technically OOB). Change your TX frequency to something above 150 and see if it starts

Do you want VHF or UHF. We have several of both also XPR8400, which we have replaced with 5700's. We would probably sell some for about $400 - $500 each, all working condition. Charlie ADAMS K3HKZ
