The best answer is "it depends." You'd like to use the back panel audio output if there is one that is independent of the volume control. That way you can set the level to whatever your sound card needs, and then you can turn the speaker volume up and down all you want without messing up the sound card. But some radios don't have a backpanel audio output and you are forced to use the headphone or speaker jack. An advantage to using the mike plug for keying and audio into the radio is that it will work with nearly all transceivers of the same brand, whereas the backpanel connectors vary a lot from one model to the next. An advantage to using the backpanel connector for keying and audio into the radio is that you may be able to get it down to a one-cable interface, rather than separate cables for the mike plug and the audio output from the receiver. Also if you use the mike a lot you can just leave it plugged in and not have to change anything physical to go from voice to digital. However - beware - on some radios if you leave the mike plugged in it picks up sound when the radio is keyed from the back - so in addition to sending digital signals you will be sending all the sounds from the room where you are operating. I have a Kenwood radio hooked up so the backpanel audio output feeds the sound card and a TNC and a Clover modem. The TNC and Clover modem feed audio into the back panel input, and use the back panel PTT line. The sound card uses the mike plug for audio input and PTT. This way I don't have to throw any switches to get from one modem to another. Need a Digital mode QSO?
