Yeah - right - and only half the bandwidth.
AMTOR/PACTOR (Sitor, etc) has been deleted from use by the maritime
services
in lieu of more productive modes.
These modes are great for the guy who wants to turn on a machine and
let it keep resending over and over and over until it finally gets it
right.
And, usually it's the same guy with a Kenwood Amp and no QSK and the
resulting
clicks wipe out half the cw band.
And - it is only for two stations, roundtables are tough. That's progress?
