RDE is somewhat more descriptive of what actually happened than
"Anomaly" or "Mishap". Mishap could describe the pilot falling off the

I am not certain how your other radios determine whether the microphone
needs bias or not.
Yes, if you are using Icom with Icom mics, those need bias.
If you are using Kenwood or Yaesu, they do not supply bias.
The bias or not question depends on the microphone used. Elecraft

The Tek 453 has two vertical input channels. Did you connect to the one

Yes, you should see a square wave if you have the vertical amplitude and
the horizontal sweep set correctly.

"Anomaly" is [or at least was during Apollo] NASA's universal term for
anything that was unexpected ... from an intermittent pilot light to the

The first bugs in the old large 1st generation computers were actually insects
(bugs) that were raising havoc with the insulation. Hence, "bugs" has become
our favorite term!
