Not as such, I'd noticed , Jose made passing comment, during the EA<>USA qso , the chat module he was using , was home made , being the sole designer of the whole VARA suite of programmes, the chat module is probably
the simplest ...
Though not designed as chat mode , the system chat module, presents a modern version of the amtor
system, though considerably faster [un reg is 170 baud max] and far lower s/n required
To work the east coast usa , used to take ~ 250 watts on 7 with my 40 ft vertical on amtor
round 25w would do the same with vara , same conditions ..
