11751Re: MSRX--An Improved Receiver for FSK441
- Oct 3, 2013That's a great question. MSRX does not decode "live" like WSJT, but can
be configured to do immediately after each sequence. So it's kind of
like the old Steely Dan song, "FM", which had the lyric, "Respect the
seven second delay we use".
You can configure MSRX to read the last .wav file received directly from
the WSJT folder. The delay is just a few seconds.
In practical terms, I keep both open during a meteor scatter session. I
look for pings on WSJT and click on the spectrum for decodes per usual.
A few seconds after each sequence, while my rig is transmitting, MSRX
will pop up with any decodes that it got. Since there is no clicking or
adjustment possible in MSRX, you basically get a go or no-go for launch.
My experience is that usually MSRX decodes slight better than WSJT,
especially on marginal pings. But there are exceptions. I've seen solid
decodes on WSJT that didn't decode at all on MSRX. Why? You'd have to
ask Joe or Claus...most of the math is over my head.
Give it a try and report back your results here. Very interested in
hearing what others think.
