This is probably not that complicated (I hope?!?) but I need a PC
program that would just tell a PC soundcard to generate a standard
CTCSS tone (example 107.2 Hz) sinewave that could be fed into an older
FM amateur transceiver. I don't want to find/buy/build a CTCSS module
for it, and will have a PC handy. I imagine a WAV file could be
created, but if there is some kind of software (perhaps a "function
generator" program) that would be ideal, particularly if you could just
give it the frequency in Hz or something like that, and get a steady
sine wave out of the sound card.

Very tks,
