should work for the receiver.
I have an R-4A, and am speaking from radio theory in general rather than from
any specific experience with a C-line receiver.
Good luck,

That's what my comment would be. Don't demagnetize! Your meter needs it's
magentas and won't work without them.
Sometimes some liquid detergent (dish soap) on a soft cloth is good for
diffusing static charge on the case. That or a drier sheet.

Jim Bo,
I don't have experience with the T-4XC, but my T-4X is exactly as you described
when operated on 160.

Do you hear the distortion the same on AM, USB, and LSB? This might give you
an idea in case the distortion originates in one of the detectors
(demodulators).

One source is the June 2004 QST. The article, by Steve C. Hageman is called
"Give that Drake Receiver a New Lease on Life".

George,
Do you still see the normal idle plate current (bias) of about 70mA when you
key the transmitter with the GAIN all the way down?

switch sidebands while tuning and get close to what you describe, but my dip in
the middle is only about 20dB, not all the way to noise.
