[Drake] T-4XC

[John Harden, D.M.D.]

So far things have gone well with the T-4XC. I noticed today that the
R.F. outputlevel has been unstable on 20 meters only. The rig is fine on
all of the other bands.

When the power is up it's full output. However, occasionally it drops
down to a low level (barely moves the external SWR bridge). I am using a
dummy load (incidentally it's a Drake I bought years ago from ACK I
think).

Any ideas before I go looking into the rig?
