[Elecraft] K3 and phase noise

Rig     1kHz    2   10   20   50   100   1M
K3      -110  -119 -136 -140 -143 -144  -150

         I'm now wondering how you measured 143 dBBDR at 2 kHz in the 
presence of 119 dB Phase
Noise?  Shouldn't the measurement have been
"phase noise limited"?

May quote from this reflector:


N6KR: "But just to give you a hint:  a couple of days ago Eric measured a
blocking dynamic range of 143 dB, and it remained 143 dB at 20 kHz, 5
kHz, and 2 kHz.  To put this into perspective, the K2, IC-7800, Orion II,
and FTDX9000all have a blocking dynamic range of -133 to -135."
