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.

The interfaces are nothing more than isolation transformers. You may or may
not need one depending on grounding, hum, or RF in the shack issues. I use
one from Donners Digital and it works great. I ordered the Microham version
because it adds USB to Serial control of the radio and CW. Has been shipped but
hasn't arrived.

Here's a few tips that are not interface related but may help you in your

Remember to set Menu => SSB => Audio source to AUX to use the input from the
AUX jack. If you set it to MIC, nothing from the Aux jack goes to the audio
input and if you set it to BOTH, your Mic is "live." Use the same SSB menu to
adjust your AUX Input Gain to a level that is comfortable with your sound card

Since the output from the Orion aux jack and supplied cable is at a fixed
level on left audio, you have to be sure you watch your AUDIO => Left setting.
If it is on "Both" you will get audio from both Rcvrs feeding into your
soundcard. Since the output is fixed, just turning down the volume on the Sub RX
does not change the level coming out the aux jack. I had a terrible time with a
double trace appearing in PSK31. Turns out I had the Sub Rx on with one VFO
set to USB and the other to LSB so both signals were showing up on my screen
but slightly offset.

One final note, the output of your computer is stereo but the input to the
radio is mono. The output of your software may also be mono. Thus, if the
computer software output is on one channel but the radio input is on the other,
the sound doesn't get from your computer to the radio. It drove me crazy. I
finally got a stereo to mono adapter plug and plugged the radio input into one
side and then the other until I found the correct side for the audio.
