![]() ![]() Well, I can't answer as to “standard” as I'm just learning myself, but I can think of a couple of ways to do this without getting into completely custom interface hardware and drivers, or needing an interface with directly readable signal lines like a serial port or parallel port which is less common these days:Ĭonnect the key to a code practice oscillator that has a line-level audio output, then connect the audio to your computer's line-in. Of course, there is no standard way to do this either, just as there is no standard communication program, or standard keying software, or standard operating system. You'd simply need to set the input of your audio-over-internet application to be the output of your morse-code-keyer application, instead of a microphone. Any application that can send audio over the internet could do it, for example, Skype. No doubt, it is possible to send Morse code over the internet. Again, no real standards, besides those imposed by the software you select. ![]() ![]() Thus, your computer looks, to the transmitter, as an external keyer. It's also possible to use some of the other control lines to drive an opto-isolator or relay which in turn connects to the key jack on your radio. Calling it a "standard" might be a stretch, but there seems to be a convention: However, most software I have seen uses some of the control lines on an RS-232 serial port. How you do this will be dictated by the software you select. ![]()
