[Elecraft] KX-1 80M Question

Ross, I live up in the northwest (Seattle area) and I think there is an 8-lane freeway between the Northwest states (Washington, Idaho, Montana at least) and Alaska.  I have had great signal reports with QRP power (on 20 meters) into KL land and some of those with portable antenna (one on a Buddistick).

I am working on my own WAS/KX3 barefoot CW only and I don't have Virginia yet.  If I don't get a VA contact in the next several months I might hunt you down for a schedule :-).

73, phil, K7PEH

I'm sure it wasn't armchair copy for any of them, but it's definitely doable. From my home QTH in VA, I've completed WAS on 80m SSB with 5W, but that was with a combination of a 160m horizontal loop at 35' and a full-sized 80m wire vertical over 56 75' radials.  YMMV ;)
