So you are probably transmitting in FSK.
Did you check the baud rate of your UART and make sure it can be set to 45.45
baud?
Yes.
Wrong baud rates usually result in some gibberish print, but you said there is
no print at all, correct?
Correct.
A reversed RTTY sounds different from correct RTTY; wrong baud rate will also
sound
distinctly different. Listen to a real life signal off the air and make sure
the
KAM prints properly, and listen again to the signal from your own transmitter --
do they sound pretty much the same?
Kam is working fine.
When you turn diddles off, does the receiver hear a single constant tone?
Yes. But, I did have to go into the TS2000 menu and invert the tones.
With the diddles turned off, do you hear an active RTTY tone pair when you start
typing?
Yes. With the diddles turned off I can send traffic to the test radio OK. But
with the diddles turned on no traffic can be sent. Also, when I try to send
traffic with a macro only part of the text gets sent before the radio dekeys.
Testing with diddles turned off might at least confirm that your typing is
getting
through to the UART.
