After my Ranger is on for a short period of time, I am noticing that
the final plate current starts creeping up slowly and will continue to
climb if I do not power off the transmitter. I have the PTT mod in
there where it grounds the screen through the 5K resistor. It does
this in any mode position until I switch off the power. I believe that
the 6146 maybe self oscillating? I do notice that the screen voltage
(pin 3) increases along with the plate current even though it is
grounded through the 5K resistor. Possibly it needs neutralizing or I
have a bad 6146? Any ideas will be most appreciated. 73, Randy, WB5KCM
