Thanks Reino. I was just about to respond when I saw your email. I actually had
to write a special program for the blind hams so that the waterfall is setup
up correctly. It actually allows them to set the start and width of the
bandpass and it then updates all the values including the bin/pixels as well as
the width of the waterfall to fit within the specs of their monitor so that
wsjt-x decodes the entire bandpass.
Had some real fun trying to decode the telemetry structure for it to work.

different issues! In FT8 mode Sam is correct as the signals are reached only on
the frequencies displayed on the waterfall. In JT65 and Q65 the situation is
different at there is a spinner called F Tol that defines the search range
independent of the waterfall range. All that is written in the User Guide. If
something else is happening, then it is extra for the operator benefit! I’ll do
a FT8 test in my next 24 h recording.73, Reino OH3mA From: k2txb--- via

Subject: Re: [wsjt-devel] Truncated Waterfall Display "Feature" Hi Sam. Well,
try it. It does work. The only requirement is to have the decode window width
wide enough to cover the actual frequency that is being received. It does not
matter how wide the waterfall display is. Of course, it is very helpful to be
able to see the signal, so being able to decode outside of the window is of
limited usefulness. But it can be done. Just got a message from another guy
who said that I “hit the nail on the head”, hi. Anyway, good luck with it. My
system is down right now for some antenna repairs and to try to fix an
oscillating preamp. Hope to be back on the moon sometime in the next week or
two. 73, Russ K2TXB From: Sam W2JDB via wsjt-devel

Subject: Re: [wsjt-devel] Truncated Waterfall Display "Feature" Hi Russ, I
don't beleive WSJT-X will decode any messages beyond the visual representation
on the wide waterfall. If the right hand side of the waterfall terminates at
2000 Hz, WSJT-X will not decode beyond that. That has been my experience. If
your monitor resolution can not display a waterfall range of 200 - 2600 with
bin/pixel set at 2, just increase it to 3 or higher as needed. 73, Sam

Subject: Re: [wsjt-devel] Truncated Waterfall Display "Feature"Sorry folks, I
agree it would seem that way. But only because there is no way to set the
decoding window if you cannot see it. I did not think of that, when I dashed
off that message this morning. And actually, if you set the decoding window
large enough, I still think it would decode signals outside the waterfall
range. For example, I set the range to 1000, and center frequency to 1400 Hz.
That will now decode anything from 400 to 2400 Hz. I still do not believe you
need to be able to see it, to decode it. Also… I routinely run my system with
bins/pixel set to 2. With the low end set to 200 Hz, it shows me everything up
to 2600 Hz. That is almost always sufficient. Don’t see any advantage to
asking for a default setting greater than that.Russ K2TXB From: Black Michael

Subject: Re: [wsjt-devel] Truncated Waterfall Display "Feature" Not true -- you
only decode what's in the waterfall. Mike W9MDB On Wednesday, April 5, 2023 at

WSJT in general, it does not matter what the settings for the waterfall display
are set to. They have nothing to do with decoding, they provide only visual
signal recognition. So, if there is a decodable signal above the 1500 Hz it
will still decode. It is much more important to make sure his receiver
bandwidth is wide enough to pass the signal at that frequency.

Subject: [wsjt-devel] Truncated Waterfall Display "Feature"
Last night, I met an operator who was struggling with EME on 23CM after
abandoning EME on the 70CM band. As soon as he started up WSJT-X, I noted his
waterfall display was set to Bins/Pixel 2 instead of 5/6 and less than 1500Hz
was displayed on the screen. All decodes 1500Hz and up were not decoded. I am
pretty sure this was the cause of his issues on 70CM together with his current
issues on 23CM and the “lack of decodes” as he complained.
I have to ask - Can we fix this so that irrespective of what the Waterfall
window displays, decodes will still occur for the full 3KHz or whatever value
is specified in advanced options.
