[ARC5] History of Ham Mods: Opinions?

[Jim Hill]

Hi Dean:
I made a quick search before answering, but unfortunately didn't find 
it.  Mine is different, because it covered the 80 meter band.  I'm 
guessing it is the first edition.  I'll keep looking.  I'll also look 
for the Western Radio Amateurs magazines.  I don't recall who 
published Western Radio Amateur, but Ed had a column called the San 
Diego Zero Beat.  There  were a number of simple phasing SSB 
transmitter articles in them.

Jim, w6ivw
