526Re: [stationpro] Re: Bleed of Audio from Transceiver 1 into Transceivers 2 and 3
- Jan 4, 2014Here is a photo of my setup showing high SWR in the switch box.
Ariel NY4GSent from my iPad
I already just re-did all of my jumpers and cables and verified each one. I placed a dummy load right at the output of the RF Box and the input directly with a short jumper and an analyzer - all the jumpers are verified good. The SWR reads 4.2. I have a post from yesterday at 3 PM that reported all the readings. I think I have a bad solder joint in the RF switch box and perhaps even bad ground connections. Should I check diode functioning? I have not opened up the unit . I needed to know whether I should focus there or not.
I have not run more than 1000 watts through the RF switch.
