* First US QSO above 400 GHz claimed: Microwave enthusiast Brian Justin,
WA1ZMS, reports what he believes is the first QSO above 400 GHz in the US.
On November 11 at 0215 UTC, WA1ZMS/4 worked Peter Lascell, W4WWQ, on a
frequency of 403 GHz over a distance of approximately 1709 feet in
Virginia. WA1ZMS set new North American records on 241 and 322 GHz last
December, and he reports the pair used the same basic gear that had been
put into service for their then-record-making 241-GHz QSO last year
(recently beaten), but with new 30-cm parabolic dishes.
