[ICOM] ICOM 736 on 60 meters

[D C *Mac* Macdonald]

Nothing had changed, Larry. One day it worked 
and the next day it wouldn't tune when I went 
to a net frequency at 3.9 MHz.
 
I guess the best course is to ship it off to an expert 
such as Scott Malcom at MTS. 
 
I sure don't want to put clumsy fingers into the set 
with nada for knowledge about such things. 
 
I suspect some failure in the logic that is selecting 
a wrong filter or tuning range for the tuner. 
 
It's a puzzlement for sure.
