    Good point on the refresh time.  I never liked tuning for a peak or 
dip using a digital meter.  Guess my analog brain doesn't like living in 
a digital world.  I've picked up old analog VTVMs for a buck or two at 
hamfests and converted them to FET op amps in place of the tubes.  Zero 
drift/warm up and all the advantages of an analog meter that runs on a 
9v battery.

     If there is any interest I will write it up after I retire at the 
end of this year.  Looking forward to more time for what I WANT to do.
