[Elecraft] 1750Hz tone in MCU 3.41 / DSP 2.37, 10-02-2009

[Wayne Burdick]

We had more requests for this than any other FM/repeater-related  
change, so apparently there are lots of legacy repeaters still in use  
out there.

This revision of firmware includes two other requested changes for FM/ 
repeater use: adjustable PL tone deviation, and repeater/PL TONE  
update during channel scanning. The new "live" memory recall (M>V) is  
also useful with repeater channels.

73,
Wayne
