David,

The mono plug will cause the problem you describe. Use a stereo plug and leave the ring disconnected.

Hello Don,

I hope you are well. You are a huge help to all of us in the Elecraft and QRP community.

Do you have the plug from the CMOS4 wired correctly?

I believe so. I bought a 3' cable with RCA Male plugs on both ends, cut the cable in half, and then soldered an 1/8" mono to the cut ends. I did make sure to wire the center wire to the tip of the mono plug and the outer ground wire to the shell/lower shaft of the mono plug. I am going to Ohm things out just to make sure.

My only other thought would be to use a stereo plug instead. If that is the case, I might need to go to Radio Shack and get another cable and some stereo connectors this time.
