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! 73. Dave. G3YXM.
