My rag chew buddies report that I have a low level hum or noise (about 30 db
down) on my audio when transmitting LSB. Previously, I had used the rig for
CW so didn't know about the problem.
It seems to be some coupling inside the cabinet, since disconnecting the mike
and keying the transmit in LSB produces the noise as well as when the mike is
connected.
Any experience with this?
