Thanks for answer Pat but this is not what i mean.
All what i mean is that if i switch from band in the wsjt-x software the ant is
not switching to the good antenna.
so a example: 20 mtr ant1 moxon 40mtr ant2 ZS6bkw so if i go in the wsjt-x
software switch to a other band say from 20mtr to

OK ! We can suspect a clipping,
Hi Claude.
I think Mike´s interpretation is correct. Third harmonics are often stronger
than the 2nd, and the variation in signal strength does seem to match the
fundamental (which, BTW, is not the TX/RX selected DF).
I see this quite frequently. A lot of hay is made on the Facebook group and
That's harmonics. If it's 100Hz wide it's the 2nd harmonic, 150Hz wide it's
the 3rd,.
Been seeing them a lot and you can divide the starting offset by 2 or 3 as
appropriate and find out who's doing it.
Quite a few ops overdriving their audio. Been more of them since Baker Island

types are defined in this file:

The signals, I have seen, have 8 tones within 100 Hz. Approximatively,
of course, because I report only what I have seen on the waterfall.
Claude,
That sounds a lot like a dirty FT8 signal that has second (and possibly higher)
harmonics.
I have a screenshot of a signal with seven (yes 7) higher order harmonics.

I have the cat port on my YAESU radio controlled by my N3FJP logging program.
I have the WSJT-X bands programmed into radio memories because the setup for
flat audio and CW audio bandwidth is different. Fast AGC for WSJT is not easy
to listen to on an SSB net. WSJT-X wants the noise blanker and

Do I understand well that you have both the N3FJP logging program and
WSJT-X communicating with the same CAT port ?

Actually the noise correlates perfectly with the signal at 940...look
again...the top :45 entry chops off about half way through the interval and the
noise goes with itplus the fact that the math works out perfectly with the
150Hz wide noise being 3*50.
I contacted that op and worked with
I have been thinking about this for some time. Went through the setup again
and things set up different now. Would anyone be willing to give me a call and
take a look at my signal.

Hi Mike,
I don't understand how you come to the conclusion that the rig could
suppress a 2nd

OK ! We can suspect a clipping, in the audio range, resulting in this

possible, but it would be surprising to me.
Heavy clipping causes (almost a square wave) which produces odd harmonics.
Very light clipping (not so square) may also include some even harmonics. If
you look at the signal with an O-scope, it is easy to see.

Claude,
I am sorry that I gave that impression.
WSJT-X runs standalone in one window, and N3FJP runs in the other window and
usually has the CAT port enabled.
Only one of them can access the CAT port.
I'm sorry to distract the developer traffic with user-radio problems and then
mislead people.
Bill,
The distortion and harmonics are in the audio section, which when over driven
are no longer linear. The harmonics that you are seeing are audio,, not RF.
The RF signal is still linear.

WSJT-X has nothing to do with that. You have set those in TS590 menu.
Hi All,
Sometimes, I have seen a strange signal on the air, in the usual FT8
"sub band". There are 8 tones in a bandwidth of 100 Hz and a TX duration
of 15 s. Is this a CLOVER signal or anything else ?
