Hi LF= 'ers

i suggest to the operators that are looking for any k= ind of ancient software for a T/A two-way contact, to have a look at

Got no answer on my request for this slow mode in future available.
JT9-5 or so would be a big deal for 160m too.

Hi Paul,

There is an old version of WSJT-X that contains slow JT9 modes. If i
remember correctly there was -1 -2 -5 and -10. Maybe someone has the old exe still available?

It is too late for this season as QRN is always high now. But for
next winter I should have 3 dB more power and hopefully more/better
receive antennas.

Modes are a bit of a problem. On the best nights JT9 would be easy
but most of the time it would probably have to be QRSS or DFCW. It's too bad we don't have a very slow digital QSO mode like JT9-10 or such.=

So, who is going to take the challenge for a dream QSO next winter?
You have all summer to get the station ready... ;-)
