[Drake] Problem on 20 meters.

[k6xyz]

Put it on a dummy load and see if the 20 meter problem is still there.
If not, the antenna/coax etc it likely at fault.

Hello all:

My otherwise fine TR4cw has developed a curious behavior; it won't transmit
on 20 meters. Works on other bands, receives OK on 20, it seems to loads ok
on 20 but modulation at the mic just won't produce the normal plate current
deviations on the meter, instead, it jumps to 250 ma or so and stays there
while you are speaking into the mic.  While this is happening, nothing is
heard on the air.  VOX will kick right back to receive when you stop
talking.

For a while, I solved this problem by putting the antenna through the
MN-2000 tuner.  Switching the tuner in and out would "fix" or produce the
malfunction.  The antenna is a TH6DXX with fine SWR as it works with all my
other radios.  Now I just cannot work 20 meters with or without the tuner.
Any of you folks out there have any idea what's happening before I venture
into the "inner sanctum" of this classic?

Carlos / KP4GL
