Re: [Jtdx-improved-community] v3.0.0 of WSJT-X Improved brings a new multithreaded FT8 decoder

Hi Stefan,

The message at 091430 looks like a telemetry message. So no false 
decode. That at 112330, however, appear to be a false decode.

The recommended settings are in the screenshot below. You may also 
consider to check "Reduce false decodes", although the multithreaded 
decoder (MTD) has (like JTDX) powerful filters to check the validity of 
callsigns.

Here on my system, I usually see virtually no false decodes, but in 
principle, any decoder can produce them. As explained several times in 
my YouTube video, our single-threaded decoder is slightly more 
susceptible to false decodes in "Deep" mode than before. If you don't 
like that, you should switch to the “Normal” setting and/or enable the 
False Decodes Reduction (FDR). But again, with MTD, you should only get 
false decodes very, very rarely, if at all. If this happens repeatedly, 
please contact me via private email. Then we can analyze together what 
might be causing this on your end.

Uwe
