I've got my twins warmed up and continue to have problems with the PTO in the R-4A. When controlling the set from the receiver, the CW tones sound raspy and the frequency tends to jump around. If I touch the shield, I can make the pitch change. Pressing on the tuning knob also seems more sensitive.
When I control the frequency from the T-4X, the notes sound beautiful and don't vary. It seems less sensitive to mechanical contact with the knob as well. Is there a way of tightening up the PTO? Why does everything sound T-7-ish when using the receiver's PTO and not the transmitter's?
