[R-390] “A” and SP 600 Heretic check-in

[Stan Gammons]

Hi Perry,

I have a machinist friends that left California for many of the same 
reasons you are. He's been in 4 land for close to 20 years now.

Thanks for your and everyone else comment on this subject.

Is the audio mod Collins made in the Y2K manual?  I seem to recall 
seeing a mod that was nothing more than replacing some of the caps in 
the audio deck with ones of different values, but I'm sure that's not 
the one you are referring to.

Thanks for all the work you've done on the Y2K manual.  It's a huge 
manual, but it's a very valuable resource!

We are forced to leave California and tentativelyplan to move to South Carolina where comparable housing is 1/4 the pricehere.  Taxes and utilities also are substantiallyless. Gasoline is $2 a gallon less.  Thereis no PC.  I don’t have to be concernedabout someone knowing I have firearms.  Ican buy ammunition without registration to the state with all my life’s detailsfrom childhood on. That's for starters.

Ray Osterwald, editor ER magazine, Dallas Lankford, Chuck Feltonand other have published articles and theirs and a few more are incorporatedinto my heretic “A” and SP 600 schematics. Also the Y2KR3 and the SP-600 anthology have almost all of theimprovements documented.

The other sacred cowis “don’t drill any holes”.  So what andwhy? Most of us don’t want are radios to look like Bonnie and Clyde’s car whenthere were killed. But it’s someone else’s radio that that person decided todrill holes. Don’t like it? OK, but no one was anointed as the public’s radio commissar.Just shut up about it.
