[VHFcontesting] The digital modes and the Sept contest

[Mark Spencer]

Although 1.2 GHz may not be considered a microwave band, I have used JT65c on that band with success during a portable outing.

It allowed us to quickly complete a QSO that had defied several attempts  over a few hours with CW / SSB.
