[Mobile-Portable] Choices for HF Mobile

[paul goble]

My FT-100D does as fine job of noise reduction as any radio I've ever
heard; too bad it's not available anymore!

I have a clearspeech speaker, but the GAP antenna noise reduction box
(from UK) works as well or better than the clearspeech.....

I use a screwdriver down to 7MHz, and a Hustler "super resonator" for
80M, these choices made to hold the size down.  Clearly a BIG antenna on
80M would be "better", but I don't have any real problems making
contacts as-is, so what the heck! - HI!

99.9999% mobile, 80m thru 23cm - "REAL mobile antennas are
omnidirectional!" - HIHI!
