[Elecraft] RTTY K3 Help

[iain macdonnell - N6ML]

"AFSK PSK31"? There's an oxymoron ;)

If you have PSK31 working, you can do AFSK RTTY with the same hardware
configuration, but use the "AFSK A" sub-mode, instead of "DATA A". If
you want to do FSK instead ("FSK D" sub-mode), you'll need a hardware
interface of some sort (could be as simple as a couple of transistors
and resistors to level-convert between a RS232 port and the K3's PTT
and FSK inputs.

Whether or not FSK is better than AFSK is somewhat of a religious debate......
