Several people suggested I run the "Calibrate transmitter gain" on my 
rig, which I'll do.  But I have one question about the calibration that 
hopefully someone here can answer - does it matter what frquency/portion 
of the band I'm in on each band when I run the calibration test?  Or do 
I just need to be somewhere in-band on each band?

Thanks to everyone for their suggestions and assistance.  If my rig 
passes this calibration test, there are a few other things that have 
been suggested which I'll check.

73 and Merry Christmas to all!
