Is that "Radcom" a trustable source,do they have all the professional measurement devices Sherwood labs have? If so,what is the difference in figures to make it better than our K3 ?


"For a refined ham it is compulsory to own a k3"

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).

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).
