*YES* with the new beta code - I'm running it and the VFO B/SPLIT
cursor is 400 Hz wide when the data sub-mode is FSK D or AFSK A.
The transmit (red) cursor only goes to 2.8 KHz when DATA A is selected.
Use AFSK A (which you should be doing for the AFSK transmit filter in
any case) if you want the narrow TX cursor.

I agree with Rick's comments above. I use N1MM for FSK RTTY. I have an extra RX
window set up to receive signals from VFO B in split mode so I can tell who the
last worked station was while I copy the DX with VFO A. With a narrow 400 hz
bandwidth and 10 khz span on my P3 I can easily tune from station to station
centering his tones in the narrow P3 curser. A 2.7 KHz curser pattern on the P3
would cover up most of what I want to see. I for one would not upgrade my P3
software until this issue is corrected. A narrow 400 Hz curser is necessary for
both VFO A and B in RTTY as far as I am concerned.

This evening as I was listening to a moderately weak station on 30 meters CW.
I noticed that the P3 display showed a wide (+-.75 KHz from center) pulse
pattern centered on the frequency I was on. I also noted that there was a
strong (XE2, not that it matters) almost 3 KHz down. The P3 pattern matched
the CW pulses of that station down band. I wasn't hearing anything but the
weak station on the K3 (well done Elecraft).
So I wondered, could this anomaly be caused by the new noise blanker algorithm?
Yup. I turned off the P3 NB function (set at 12) and the anomaly went away.
So if you're seeing something on the P3 that isn't there, turn off the NB
function and watch again.
On the subject of the Data A red pattern width change; my normal set up for
working RTTY/PSK (AFSK, Data A mode) split was:
Narrow and recenter the filter to hear only the station I want to work (sound
card doesn't get hosed);
sync the two VFOs (double tap; copy everything over to B);
go split;
move the VFO B (now with the matching pattern of VFO A RX, in red) on top of
the last station worked, fine tune by listening to the sub-RX if desired.
The former (pre-beta) pattern showed the same narrowed width as the main RX
(shows the slot my audio tones would go out), which made it easy to spot the
(TX) VFO B on or near the last station worked, simply line up their trace under
the red swath. This makes for a nice quick attack mode.
Having the wider red pattern (2.7 KHz) makes this much harder now since I can't
'see' where my tones are going to be. If given a vote, I like the old way
better if the P3 can't read the filter width and match the display to the
actual. At least I had a ballpark idea where my tones would go.
