General discussion forum / Hum Sound on Transmit with TS-2000
« on: 2012-06-16, 09:20:11 »
When I transmit through the RRC units on the same LAN I get a very loud humming sound heard through a separate receiver. I can also hear my voice come through a little, but mostly hum.
If I connect the Microphone directly to the radio there is no hum. If I use the cable I made to go from the RRC to the TS-2000 with an adapter allowing it to be connected to another microphone there is no hum - so I think that cable I made is OK. There is no hum on receive, only transmit with 5 watts VHF/UHF/HF.
Prior to using the TS-2000 I was using a TS-480 with these RRC units and it worked perfectly. This is just an upgrade. Everything works except for this hum on transmit.
I also tried moving the control RRC to another AC power outlet in another part of the house. The radio is running off an Astron 35M and the RRC radio is running off the 1am wall wart.
Any help would be forever appreciated.
