[R-390] LW reception on R390A

[Bruce]

Thanks for the info guys. I've got about 700' of antenna stretched out, and
I am able to hear a few beacons on my other rigs, just wanted to see how the
'390 faired in this nether-region. 'Course DXing LW in the winter months
would have been a lot more rewarding, hi.
