	Rob Sherwood has updated IMD measurements for the
FT-1000 Field, Elecraft K2 and IC-7800:

Nice to finally see some consistency in results for the FT-1000D,
FT-1000MP, Mark V and Field.  It never made sense to me that
ARRL measured such great differences (10 dB).  Apparently that
may have been caused by W8JI's famous Noise Blanker problem
(with the units under test having different settings even with NB Off).

	I understand we may soon see some independent
measurements with the Inrad roofing filter installed.
