I have the whole shack in turmoil with wires all over the place trying to
make Jason work across the room.
I am using sound-card TX mode as I have an SSB exciter on 136 kHz so I can
transmit Jason OK if anyone wants a test.
I adjusted audio level to get nice clear thin lines on the spectral display,
centered between the yellow lines.
Even when connecting audio direct from TX PC to RX PC I still can't get a
good copy.
I just get occasional wrong characters like / or ,


I have discovered:
It seems to work on every PC I've tried, no problems like with Spectran.
Even the 100Meg machine sends OK but I have yet to get a good decode.
My RX PC is a P200, is this fast enough?
Tomorrow I will try an 850Meg machine, if that doesn't work I will be very
confused...

Operational questions:
How do you clear garbage from the RX screen?
Do you need to start the TX after the RX is running or will it pick up a
signal half-way through a long message?
Is there a way of transmitting a long start tone (seems to be centre
frequency) for alignment purposes?
How long should it take to display a character on the screen?

Very exciting, I like to have new toys to play with!
