[RTTY] QUESTION

[Don Hill AA5AU]

In order to key FSK, you must supply on/off (short/open) keying to the FSK input
of the radio.

This is normally done in various ways - TNC FSK output, RigBlaster FSK output or
a simple transistor circuit coming from a COM serial port on the PC.

For a simple transistor keying circuit to key FSK (and PTT, CW), see:
