Actually, since March of last year, CW, RTTY and data are now allowed on the
60 meter frequencies according to the latest reports I've seen from the ARRL
and FCC. The emissions must adhere to the 2.8 kHz bandwidth allowed.
The ERP was raised from 50 to 100 watts at the same time.

Actually, CW is legal on 60m, you just have to center your signal in the

The problem is that both solutions occur *after* the A/D converter in

It also works wonders to filter out loud PSK31 signals that are
overloading your audio A to D converter. Too bad auto notch
doesn't work in this situation. (I'd go after the strongest
signal in the DSP filter pass band.)

Along the same line, when I go back to RTTY, it comes up at 75 baud, where it
was last at FSK-D and 45 baud. I'm using the remote system if that makes any

The K3's notch filter is designed to filter out CW signals. It's
about 200 Hz wide, not much more than that.
