TERRY,
..
The RadioShack DX-398 / Sangean ATS-909 is 'noted' for being the
exception to the rule; that most 'portable' AM/FM Shortwave Radios
have a tendancy to OverLoad with a very long (+100) Wire Antenna.
..
Conversely, some complain that the RadioShack DX-398 / Sangean
ATS-909 is some what deaf on it's Whip Antenna when compaired
to other 'portable' AM/FM Shortwave Radios.

I am happy to learn the DX398 is above par in that regards.
I thought that I had read somewher that it was fairly prone to
overload.
I have used my R2000 with about 800' of wire up in a nature
preserve and had no noticable problems. We camped out,
in a VW transporter, and I listened on and off for 2 days.
BTW your antenna site if a very well organised place and
full of interesting info.
