Hi All,
Ed may be right--it's hard to say. It also depends on what the definition
of disappear is, meaning I think there will always be some adventurous
souls using CW regardless of where technology takes us. By rights, I would
have thought AM would disappear, but it hasn't--not totally.

Actually, the fundamental cause is that those tuners use the chassis as

Phil,
That is correct. The battery '+' and external supply '+' are connected
together. The voltage at the battery's negative terminal is measured
and subtracted from the voltage at the '+' side. So with no batteries

What I am curious about is: Will they stop the use of AM on the MW

Check the number of lockwashers you used under the Front Panel standoffs
