bias supply probably the problem, bet the bias voltage is way down
(less minus), and getting worse. Replace the electrolytics in the

Ok, got a good one....my t4x just started showing cathode current even
when I don't have the key down on the mike or the cw key..its there all
the time and I can hear a carrier on
my r4 all the time...doesn't matter where the controls are set...seems
the finals are in transmit all the time and the relay isn't pulling in,
it only pulls in when I key the mike..I can even hear my voice in the r4
without the key down...hmmmm.....
