Thanks, Gary (and Tom, who emailed privately). That is good to know. 
Sometimes you get what you hope for! BTW, my 120 is an excellent 
tuner - has a greater range than the AH-4 - can tune my LONG whip to 3.6 MHz.

Mine worked right off the hamfest table - needed no mods. There may 
have been two models, because I have heard the mod story before and 
also saw pictures of the circuit board on one that needed mod and 
that picture did not match mine.
