Configuration, RRC 1258 / No Mic output to rig

« on: 2015-04-09, 21:40:47 »

I have a new pair of 1258's with 2.85 firmware, and everything works EXCEPT no Mic audio output at the Radio.  There is bias on the Mic at the Controller end, so that is working; the Mic works plugged into the Radio, so it is OK.  On the Radio end I can trace the Mic input and ground all the way to the transformer on the 1258.  Is there a troubleshooting sequence I should be following to resolve this?

Hardware, Cabling, Installations / Remoting a Flex-5000A

« on: 2013-02-20, 23:44:52 »

My plan for remoting a Flex-5000A is to handle the video with Remote Desktop and use the RRC-1258MkIIs to provide stereo Rx and (mono) Tx audio, plus a CAT serial link.

The radio's stereo Rx audio is intended to drive PC speakers, and the remote audio will use the stereo miniature phone output to do that.

On the radio side, it looks like my best option is to remove R82, R137, R102, R103 to raise the "speaker" input resistance to about 1K, instead of the original 50 ohms.  Is there an easier way?
