[TenTec] Orion and digital modes?

[Dennis Bryant]

Thanks for this information. I tried to use my Orion on PSK31 for several 
weeks and never could get the right hook-up. I called TT about my problems 
and they tried to help, but they seemed not to have a good handle on this 
either. The manuel was no help although the old manuel was more help than 
the new manuel. I finally gave up, but maybe I will try once again. I could 
not get the radio to transmit. I think the stereo to mono adapter may help.
