[ICOM] Encoder for IC751A - main tuning

[Lee Mairs (SAG)]

I guarantee that if you remove the battery from the IC-751A it 
forgets completely that is a radio!  Don't ask me how I know this, 
but there was a company that sold a replacement module that "hard 
wired" the requisite code in ROM so that you didn't have to worry 
about changing the battery.

DO NOT attempt to change the battery on an IC-751A without a parallel 
voltage source!
