[Elecraft] Full Break-In (QSK)

[K9MA]

The dits are a bit short on the FT-1000 in QSK mode, but I don't know 
how much difference that makes. The FT-1000, in any case, is much slower 
that some of the receivers I used long ago. Alas, I have none of them to 
test.

The FT-1000 is notorious for its key clicks, the reason I don't use it 
any more. I don't think that is related to QSK, as it's just as bad in 
PTT mode.
