Quite often mic connectors are used -which may explain the misunderstanding. I do agree that the sound card might not see this but a KEY or KEYER usually is contact closure - hard contacts or electronic. If I solder the shield wire to the outside conductor and the positive to the inside conductor of a mono plug, will one of the stereo channel inputs on the line input work? In other words, is the phono female jack designed in such a way that a mono plug will work with one channel?Ī keyer is connected to the KEYER or KEY input of a transmiter or transceiver - not to the microphone. The name of the software is CW_Player, for anyone interested.Īudioguru, I don't have any phono jacks lying around, just mono. Anyway, I just happened to have a tone generator lying around that I used a long time ago for testing speakers, and I figured it might work if I wired up the momentary switch and mono jack, just for fun and for practicing. Actually, it did say a CW keyer, which logically implies that the keystrokes generate a continuos wave. Therefore, I am working on assumptions, and the freeware software only says to plug a keyer into the mic input, not specifying the characteristics of the keyer. I haven't purchases or built any real equipment yet, because I am not going to take for granted that I will pass the test. Like I said before, I am studying morse code in preperation for my Ham license, and from what I understand, Ham operators plug a keyer into the mic input of their radio equipment and communicate with morse by modulationg a continuous wave (CW) audible signal on the carrier frequency, creating dah's and dit's that can be heard at the reciever.

Can anyone confirm that? I was just working on an assumption there.

I am not sure, but I am assuming that the audio inputs of the card are isolated, so it would require AC for them to see anything.
