General discussion forum / Constant Buzzing Sound in my Transmit Audio
« on: 2020-05-28, 02:39:28 »
I am getting reports of a constant buzzing sound in my audio, I am using a RRC-1258 mkII connected to my Kenwood TS-480HX. The buzzing only seems to be present when my control unit is running off the wifi.
This is what i've done so far
1) I have tried both wiring methods for the jumpers for the 480
2) I have tried different 12v power supplies. Even tried it off my Vehicles battery
2) I have tried running the audio quality down on 0 - alaw 8khz, the buzzing just about disappears, but so does my audio
3) I have tried running the audio at 1 - Linear 12 bits 8khz, the buzzing is reduced, but my audio reduces as well
4) I am running in program mode 5
5) I set RTP tx mode to continuous
6) Both com ports are disabled
7) I increased rx jitter buffer to 10
I increased rx jitter delay to 9
9) I set audio packet size to 20
10) I have checked continuity on the straps right at the socket level
Any thoughts would be appreciated
