Hello Jose,
I always set the sound card volume , the modulation, that when changing the

This is very important in particuar for WSPR and WSPR-QSO modes.

The reason that radio amateurs discussing automatic operation would use

WSJT features an "auto" checkbox, which, when enabled, automatically
switches to the next message in sequence, after each over. The transmit

One of the columns shown in the WSJT main window (where signals are
decoded) is "DF". This stands for "delta frequency" and displays how
many Hz +/- you must tune to be exactly on top of the decoded station.
As for logging RST, I always use OOO. It's weird for HF, yes, but is

It is true that, for a good number of QSOs, JT65A's insane sensitivity
is not needed and you merely take a lot longer to exchange the QSO
data than you would with another mode. However, I have completed a
number of QSOs that simply would not have been possible otherwise.

Hi,
The appeal of JT65 is multi-faceted...works great deep into the noise
so I can work stations as meager as more own at some distance. Also
the freq tolerance, as you mentioned.
It is automated so a double right click on another call sets things
in motion - sit back and watch!
Socially it me
but the nature of the WSJT software is that it will decode signls within a
600 Hz range. So, unlike many other modes, even if you are off frequency
and not able to hear anything...it will decode.

You can type anything you want in the TX1 to TX6 message boxes, they have to
