TNX Brian! I did find the FOX version of ALL.TXT. I think what I was
apprehensive about was whether stations were being automatically logged
when I sent RR73. I don't recall seeing a pop up screen that said they
were being logged, but maybe it was because I was trying to manually log
them. The last thing I wanted to do was run SFX for several hours and
then find out it wasn't actually logging the stations.... Will try
again! Thanks! VY 73, Lance

Hi Lance, your contacts should be showing up in your regular log file;
in addition, there's a file, FoxQSO.txt, that keeps a record of sent
and received communications while in Fox mode.

I tried SuperFox today for about an hour, and I am not sure I figured
out how to use it successfully. And I am not sure the callers
figured it
out either. But I did notice that all the callers were low in
frequency. I was receiving on my AirSpy R2 on 50.296 but I had to
TX on
50.295 because I was using an offset of 750 Hz. Maybe that is no
longer
a requirement. Anyway, for some unkown reason all the callers
were low
too, as if they were TX on 50.295 instead of 50.296. After seeing
this
email, I made sure to quit WSJT-X after running FT8 and start it up
again before running Superfox.
I am having internet access problems down here in ZD9 but will
try to
study up on Superfox and basic F/H tonight. I don't have a good
way to
practice it except to run it on the air like I did today. There
was no
automatic logging of stations that I was sending RR73 to, and I
imagine
this is supposed to happen with a program that is supposed to achieve
such high contact rates. I had to click on a station's callsign so it
was in the DX CAll box and then I could manually log it without
getting
a logging error message. I was assuming that contacts made with
SuperFox
just are added to my usual WSJT-X ADI log, along with all my other
FT8
and Q65 contacts, but I don't seem to be finding all the SuperFox
contacts there. I hope I can figure out how to properly use it
because I
was having dozens of callers at once today, and I expect the same
to be
the case all week now that 6m cndx are improving... MNI TNX and
VY 73,
Lance
