More from the stupid question file: What kind of power supply are you
using? Is it providing enough current?

I don't trust the power output indicator on a radio. Use an IC-7000
and an 857d portable. The 857d has a voltmeter that indicates B+.
Keeping an eye on it before, duing and after key down gives me a feel
for what the battery is producing.

Could also be desense. If you've got a cavity handy and a way to make
a  return loss measurement (tune it), it's worth a try! My Times
Technologies T-100 has this function. Present generation is 200$ on my
fave-rave auction site.

Find the bug, prove the bug, shoot the bug.
