Radcom's tests, under Peter Hart G3SJX, are just as trustworthy as ARRL and
Sherwood, and in fact have more continuity (in longevity of personnel,
equipment and procedure) than ARRL and maybe a bit more integrity than
Sherwood.  I say the latter because Rob has had the K3 listed #1 even though
both the Flex 5000 and Perseus exceed it at 500 Hz BW.  The only reason the
K3 is ranked #1 is that it uses a narrower bandwidth (200 Hz) than the other
two rigs to achieve the #1 position.  Rob has this clearly footnoted but it
still doesn't seem right to me to list the K3 at the top based on footnotes.  

With equal 500 Hz BWs, the 2 kHz IMD results are:

Perseus - 99 dB
Flex 5k  - 96 dB
K3        - 95 dB

Someone may forward this to Rob which will be no surprise to him since I've
told him this directly.  Frankly I doubt many would notice the difference
between 95, 96, 99 or even 101 (with 200 Hz) so I don't understand why not
rank rigs at identical bandwidths (500 Hz).

73,  Bill

P.S.  It is not "compulsory" for me to own a K3.  I own a K3 because it
offers me the best performance available at this time for my set of needs. 
(Best performance meaning excellent strong signal handling and true
phase-locked diversity).
