17 just wasn't happening for me. It was fairly quiet, but the only station I ever heard well was the PY2 that squatted on '140 for a while. I caught a little of a good sounding station in Nevada working on 18.140, a "6" call, when I first sat at the rig.
Also, I think I heard a faint whisper of CW ... surely it was Dave calling me, but I couldn't even copy that!
Being short on time, I never checked any other band.
