Ok I see.
Then someone better update the info in the INSTALL file
(https://sourceforge.net/p/wsjt/wsjtx/ci/master/tree/INSTALL):
The Hamlib library is required. Currently WSJT-X needs to be built using
a forked version of the Hamlib git master. This fork contains patches
not yet accepted by
Thanks for the explanation Joe. I had not seen that before. Signals do not
affect the noise estimate which was one of the answers I was looking for.

No...that particular fork was created when Hamlib was not getting updated.

I thought this particular fork was necessary for WSJT-X and not the main branch
of Hamlib?

Thanks for comments Reino and Andy. My 20 dB degradation number was based on
an actual measurement using FM mode on my radio. Basically injected a signal
into the antenna feedline which was terminated with a 50 ohm load. Measured the

I really have no data to compare as you suggest, and the results are purely
annecdotal.
The way this got started was that on 2 meters I suffer from local rfi, usually
these are suspected to be chargers in the vicinity. In engaging filters I
noticed the rfi become enhanced, by
Hi Andy,
Interesting approach. But how you know that it really enhanced the signal
detection?
The wanted signal is now close the wanted signal and that may disturb the S/N
calculation and you will see a better S/N values with your method without a
real better sensitivity. Possibly the only
Joe,
Just a comment here. I use FT8 frequently and almost always on 2 meters. My
interest is in weak signals. I use a Omni VII here, with a transverter. I
have had some luck using my notch filter on very weak FT8signals. Setting the
notch width at about 75hz, I have been using the edge of
Hi Joe,
Some quick comments in-line.

Does it simply collect all the signals and
