General discussion forum / Bah! "Hum" Bug!!

« on: 2016-12-14, 20:54:07 »

I have gotten everything working with the remotrig, except for one thing....There is a "hum" that limits the amount of audio gain I can use.   I have checked everything for ground loops, etc, but haven't stumbled on the cause.   I do notice that there is no direct  ground connection between the circuit board ground and the chassis or case.  Would there be any contraindication to adding a short ground wire between the circuit board and case to reduce the chance of a ground loop? 
I have added an audio isolation xformer between the microphone and the input which has helped some but not enough  to eliminate the hum.  What about adjustment of the audio "codec" gain or attenuation?  Not sure I totally understand these adjustments to vary them from the default values. Suspect the "boxes" could be set to sensitive?
Thanks,

Configuration, RRC 1258 / Tentec Orion setup

« on: 2016-11-11, 22:14:29 »

Ordered pair RCC 1258mkII on basis of uses described in description on web page under conventional PC remote.  But further looking in the manual, can find no information  configuring for the Tentec Orion. I have full computer control of the radio, tower raising, rotator, logging and can access the "Radio" computer over my LAN.  I ordered the units to simplify the whole set  up and to be able to connect audio to the transceiver.   I also anticipate adding an automatic amplifier to the setup.   Can you direct me to information  to configuration for setting up to use the Orion? I have computers at the  (Radio) and at the remote operating position connected via LAN.  Thank you.
