the FSK connection

Transceivers capable of [:AFSKFSK:FSK] operation generally provide a [http://en.wikipedia.org/wiki/Transistor–transistor_logic TTL] input (voltage levels +5 VDC, 0 VDC) that controls the switching between Mark and Space frequency generation:

WinWarbler can be configured to generate this signal

  • using [:PTTMechanism:PTT serial port's] TxD signal

or

  • using the TxD, RTS, or DTR signal of any available serial port

All of these signals employ [http://en.wikipedia.org/wiki/Rs232 RS-232] voltage levels (+12 VDC, -12 VDC), so an external level converter is required. This can range from a simple one-transistor circuit to a section of a commerical interface.
