[Elecraft] K2 vs TS-2000 (etc.) receiver

Wed Nov 27 09:42:01 2002

Roger's report doesn't surprise me at all.  I have an IC-756PRO, which
incidentally in direct A/B comparisons could occasionally out-hear its
predecessor an FT-1000D, long considered probably the best transceiver money
can buy.

In showing off my K2 to visitors in the shack, we've done many A/B
comparisons between it and the PRO.  In dozens of cases, we could hear a
weak signal in the presence of very strong and close interference on the K2
that were difficult-to-impossible copy on the PRO.  Never has the reverse
been true.  In a few instances the K2 was even "armchair" copy!

Welcome to the wonderful world of Elecraft!!

Sorry, Andy, I don't have any way to record and send it to you, but trust
me... it's impressive.

73... Ed, W5EJ
