HF JT65 and JT9-1

A few people have suggested I try these modes more seriously. I have used both these modes in the past but never too seriously. As I cannot do much building or "in the field" experimenting until my health really improves, these modes will provide me with a "no talking" challenge for the autumn - my voice is still poor making modes like SSB challenging. I can manage VHF and UHF contests for short periods, but it really strains my voice and voice modes are best avoided. Unlike WSPR which is an excellent beaconing mode, the JT modes are 2-way so allow proper QSOs, if rather rubber stamp. WSPR is a few dB more sensitive but JT65 and JT9-1 use 1 minute transmission slots.
