Hi Carl, You’ve got lots of great stories. BTW we got our ticket the
same year. I was wn0zke in Kansas City, upgraded to General, then
lived as G5APG in England for a year, then to Ohio as w8kfl. Got my
present callsign sometime in the 1970s. Been active the entire time.
My first wife almost left me because she kept bumping her knees on the
KWM1 in my Corvair. The Corvair is long gone, as is my ex-wife, but
I’ve still got the KWM1.
73,
Jim W8ZR
