Rob Sherwood, NC0B, an independent and well-known receiver performance
specialist, has completed his K3 receiver tests. We're pleased with the
results, which will place the K3 at the top of his comparison chart.
Rob will be updating his web site in a few days. For now, I'll just
mention a couple of his numbers (with his permission).
Elecraft K3, S/N 00149, 20 meters, preamp off:
Dynamic Range 20 kHz 104 dB
Dynamic Range 5 kHz 102
Dynamic Range 2 kHz 101*
* with 200 Hz 5-pole filter
Blocking above noise floor at 100 kHz spacing, AGC On: 140 dB
Phase noise (normalized) at 10 kHz spacing: 138 dBc/Hz
Rob performs some tests differently that we (and the ARRL) do, but in
general we're all in close agreement. Note that the unit under test had
only Elecraft 5-pole filters. Our tests show the 8-pole filters to be
as good or better, and we sent some of them to Rob to test when he gets
a chance.
