    Mike wasn't talking about BayCom modems. He was asking whether the PTT
    circuit shown at that baycom address was ok...

    I have used a homemade interface where the PTT connection is similar to
    the "Serial Port Solution" on that page. Also I have no isolating
    transformers in the audio paths. I have had no problems with the setup
    even though my HF antenna (a random wire) is only a few meters away from
    the rig/pc.

    However this is something everyone seems to have his/her own opinion and
    they're all probably right. There are so many variables in a typical
    station setup that you will have to try to see if _you_ need DC isolation
    or not.

    I don't know the Rascal kit interface but to me $20 seems cheap. Just
    buing a decent enclosure for a homemade project can easily be more
    expensive...
