I'd like to test my machines and FSK converters by sending a text file from my Windows 7 machine. I don't want to do anything other than set mark/space freq and speed. Everything I find wants to control my transceiver, display waterfalls, automatically reply 599, enter into logbook, etc. and I can't figure out how to just send audio.

I don't want to hook up a COM port (not even sure if I have one) - just plug into the headphone jack and drive my Dovetron.

I need something Simple, just like me.

Any recommendations?
