    You definately need the circuit as describe on Tom Sailer's page.
    But maybe the Tekk is keyed differently internally?

    No.

    No. My radio does not transmit before I configure the drivers.
    (By the way, I use the same circuit to key my HF rig under Windows.
    No problem there either.)

    I think Debian is pretty good in that area already. (Disclaimer:
    I'm a Debian developer.)
