Guy is correct, I have a ham living about 700 feet from me, and when he opens up with his KW, my old Icom used to die... The K3 does not even let me know he is on if he is beyond 10 to 20 KHz. Only way I can tell is a HUGE spike in the P3 at his operating frequency.
I did a very informal set of tests located at http://nk7z.net/wiki/elecraft-k3-macros/elecraft-k3-xlr-to-radio/elecraft-k3-new-synthesizer/ using the P3, and looking at the new synths, as compared to the old synths. The screen shots show how very tight the K3 really is when placed next to a strong signal... -- Thanks and 73's, For equipment, and software setups and reviews see: www.nk7z.net For MixW support see; http://groups.yahoo.com/neo/groups/mixw/info For Dopplergram information see: http://groups.yahoo.com/neo/groups/dopplergram/info For MM-SSTV see: http://groups.yahoo.com/neo/groups/MM-SSTV/info On Fri, 2015-08-21 at 10:53 -0400, Guy Olinger K2AV wrote: > PVRC contest club members have known this very useful fact for quite a > few years now.
