[CQ-Contest] 40m lower band edge SSB

[Dave Edmonds]

I recently got out of 'band jail' by upgrading to Extra...What freedom it's
been to enjoy the whole band to 3 Khz on the edges. I learned my lesson as
a Novice when working PJ2PP on 21.099. I was using a FT101EX and I didn't
recalibrate the dial VFO. My dad shared the "QSL card" I received from the
FCC with me... I'll never make that mistake again!
