[Drake] FW: 2NT with a VFO??

[D C *Mac* Macdonald]

My WRL 755 VFO I built from the kit was VERY
stable. I used it on an AM rig and after doing
a careful zero-beat, I chatted with may SSBers
back in the 1960s and they were unaware that
I was on AM until they checked my "unwanted
sideband supression." HI!
