    I finally got around to a project that's been on my list for a long time, adding a soundcard interface to my
    Ten-Tec Argo 555 QRP SSB rig.

    I just finished the circuitry and have written up a full description of the project here:

    I've been pleasantly surprised at how well this setup works for PSK-31, I made quite a few contacts
    the first day I got it running. I also managed to have a fairly lengthy 20M rag-chew (Colorado to Michigan)
    using the Contestia mode. Thanks to forward error correction, copy was close to 100% for the whole QSO. Not bad results considering that I was using a fairly low dipole aimed N-S.
