My guess is that the overcurrent trip is too sensitive and that the PA
bias in the radio takes longer than ten minutes to discharge, so that
immediate restart lets the PA transistors draw too much current while
charging the filter capacitors in the radio.

A slightly annoying problem has shown on my 0mni 6 + 961 PS.
Rig works perfectly unless I turn off AC power and try to restart immediately
or within about 10 minutes: The power supply goes into motorboat mode, cycling
about 5 Hz.. Makes no difference whether it's off by switch on rig or PS - of
course the two switches are essentially series'd so shouldn't make any
difference. If I leave power off a while it starts and runs quite normally.
Any suggestions before I put the scope to work? Dave K3TX
