My Argosy II / Model 225 power supply combo began acting oddly tonight.
On 20 meters and above, the power supply's circuit breaker is tripping
when the rig is keyed -- even when working into a dummy load. Antenna
connections are fine. This behavior began tonight -- I've never had it
before and nothing been changed i the station setup..
So, it appears that either the current sensing circuit has gone bad or
the rig really is drawing excess current on the higher bands. I'm
baffled. I reset the tripping point in the power supply, but that's not
the way to fix this.
Any ideas?
Many thanks and 73,
Craig
