OK, my SSB output was low too.  I'm on phone so rarely, were it not for 
the reflector, I'd probably never have checked and when I did find out, 
the thread would have already died.  I did the TX Gain calibration as 
Wayne suggested, all seems to be well on all bands.  Apparently, the DL 
in my MFJ tuner isn't all that 50 ohms-ish on 6m, but the trusty Heath 
Cantenna is.

The APF feature is really quite amazing.  I have to miss SS CW, family 
stuff, but I'm anxious to try it out for real.  It already got me 9U0A, 
he was whisper weak, maybe S[minus]1, I got "9A" and wondered why the 
pileup on a 9A?  APF in, he sounded S5.  S-meter was still on the peg 
however.

73,
