[Elecraft] KX3 and FreeDV

[Walter Underwood]

I set up FreeDV once, but it was a while ago. It is exactly the same as setting up any digital mode for radio connections. The difference is that you also need to hook up a headset (or mic and speakers) for the operator. Get the radio side set up first using test tones.

Set your levels (4 bars with 5th flashing on transmit, best decode on receive) and away you go. I am not familiar with FreeDV, if it has the ability to do PTT over com port you can key with that, otherwise you can set up VOX. KX3 does not do FSK, you have to use AFSK. Not a big deal, just keep an eye on the transmit level.
