I stand corrected, thanks

Thanks Mike,
I see on 40 m band a bit different distribution of S/N values. In my case
typical average S/N value is about 5 dB higher than yours and standard
deviation is a bit below 10 dB, while in your case it is 8 dB. The interesting
point is the -24 dB value. In your case the lower the less
Hi Uwe.
I get this error when compiling Improved_PLUS:

Hi Jarmo

Hi all,
The download issue should be fixed now. Something was broken at
Sourceforge. The SF support team told me "there was an error with an

that popup message I posted was from -Z. It too objects to running Fox in

HI Reino,
When I added the SNR analysis to my Alltext.exe program, I made sure that I
also displayed the Hi and Low values. I wanted to compare those values relative
to the mean and the 1 StdDev value, especially the low value.
It really was an interesting exercise especially seeing the variance

Hi Mike,
Perhaps I need to do the same search. I remember that Bill (sk) mentioned that
the -24 dB is used in WSJT-X for FT8 because the accuracy is so poor below that
value, but may be changed. Not a big issue.

Yes, 3Y0J had this problem while their DT was within limits. And indeed
some clever op's managed to work them.
Is it possible that these op's used MSHV to match the wrong period?

Hi Sam,
Thanks Sam, I am aware of that problem and for sure it affects to the
"absolute" S/N values. There is another issue due to the limited dynamic range
and that all S/N values below -24 dB are reported as -24 dB. I have partially
tried to avoid the issue by only taking into calculation mes
Wasn’t there a dxpedition recently that inadvertently had their clocks off by 13 (?) seconds, and no one could work for them because they looked like they were on the “wrong“ period?A few people were able to work around the limitations above, or set their own clocks off by an equivalent amount, and
Hi Reino,
The one thing to be aware of when analyzing SNR is that since you can not
account for the signals that you did not decode, those that are below the
threshold, the mean will always be biased towards the positive side and those
missing decodes invariable would have affected the variance
And for additional clarity - something many OP may not try. If you try to
switch to Fox mode on a std frequency, you will be met with this popup

You will not be able to TX in until you switch back to Normal mode or
change to a non-std frequency.

All correct. I've just emailed T30UN on this very subject. Their QRZ page
is completely misleading - what they are saying is absolutely not possible.
It's not F/H if they are on std freq. It's MSHV multi-stream. But they say
they use WSJT-X. So this all leads to total confusion for all operators.
OK, thank you all, I didn’t know that.

Hi Ton
Those msg for different stations in a single stream and on the same time
is mandatory for FT8DX Mode (WSJT-X F/H) but they can also be made by
the MSHV Software and if a Station is TXing on the 15/45 periode and
send out those msg for different station it can't be WSJT-X and it's not
t
MSHV also does what they call Multi-stream and also multi channel or “slot”
To work a station running MSHV, you do not have to obey the rules of Fox and
Hound associated with WSJT-?.
You work them as normal but they are able to reply to 2 station at once on one
sub-frequency or multiple slots s
The messages had different reports for different stations in a single
stream., my understanding is that this must be WJST-X F/H..
Please correct me if i am wrong.

Hi,
Just as promised, I looked what happens, when I set waterfall from 200 Hz to
1500 Hz (just bit more). The measurement was a side result of a study how a
narrower radio filter affects to the S/N values. I have two similar receivers
and I feed the same antenna signal via a power divider to th
