Weird....   Had the VOX gain at 60, changed it to 40 and it's OK now.  Set 
it to 100 and it's still OK.

What's weird is that there was no mic connected when it was acting up.   I 
had also unplugged everything except 12V power and a dummy load and it 
failed every time.

Seems that simply changing VOX gain did the trick.

It's not 4/1/2009 already is it???

73 all    Bill  N2BC
