In the US, CW is legal in all frequencies of all bands except 60M. For most
HF bands, digital is only legal in the lower part of the bands -- AKA the CW
portion.

Actually, CW is legal on 60m, you just have to center your signal in the
"Channel". So is PSK, but not what we know as RTTY, despite what the
rule language says, at least yet.

I was under the impression that CW (and Digital) were legal in the phone
bands, not that I've ever tried them there.
The problem isn't bandwidth as much as just plain poor operating
practice. Automated stations should not be exempt from the rules, or
common courtesy.

Just wait until the ARRL proposal for a 2.1 kHz digital mode
bandwidth in the CW/digital segments passes.
2.1 KHz bandwidth ... try 3 to 5 KHz!
I'm waiting on the Commission to post the proposal for comments -
then I will object to the unregulated bandwidth *and* propose that
RTTY/DATA be all

Bob,
Instead of using a notch filter, how about narrowing the DSP filter
width to select the signal that you want.
Look on the waterfall for the audio frequency of the signal of interest
and adjust the SHIFT to that center frequency, then narrow the width to
isolate that signal.
It is much m

The problem is that both solutions occur *after* the A/D converter in
the radio! One wants to get rid of the "big signal" or the multitude
of moderate signals before they saturate t
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.)

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

Howdy K3' people:
I am looking at some signals I'd like notched out. I am using WSJTx, a
Data-Mode .On 30m there is some constant garbage I was trying to remove.
However, it seems to be about 100Hz wider than the apparent notching
