Note that the BDR of the K2 is second only to the Orion (115dB versus =
119dB. I think I understand BDR, but I'm not clear on IMDD3. How does =
this affect us under real world conditions? I'll go over to the ARRL =
site and see what I can learn.

RE:  K2 Rig comparison chart.....   =20

Several K2 owners have Tentec rigs and several Tentec owners have =
Elecraft gear and belong to both boards.

It is the Expanded Test Report rating list that is what caught my =
attention and where the our beloved K2 is ranked so far down the list =
......
=20
The red numbers for the competition posted on the website can be =
corrected quickly but will having a newer K2 with all modes submitted =
for ARRL re-evaluation change the results of where the K2 stands in this =
most recent ranking of radios?  The competition will use this report as =
the ready reference for all...........

Listed in order of 1 kHz IMDDR3 results:

Radio IMDDR3 BDR (interfering signals at 1 kHz)

TT Orion 84 dB 119dB
FT-1000MP 78 108
IC-756PRO 75 104
IC-775DSP 73 103
TT Omni VI+ 71 85
IC-746PRO 70 92
IC-746 70 88
IC-756PRO2 69 92
FT-1000MkV 69 100
Elecraft K2 66 115
TS-870 63 87
FT-1000Field 60 88
JRC NRD-535 50 86
IC-756 50 85

This quote is then added =20

" Also, it is interesting that the K2 goes from stellar performance at 5 =
kHz to one of the worst at 1 kHz. This may have to do with the quality =
of the K2 CW filter which was available at the time of the test (unit =
was S/N 495) which has subsequently been improved for  S/N >3000 (a mod =
is available as an update for older units). I understand ARRL is doing =
another test of the K2/100 which will probably be more meaningful, so I =
would take these results with a grain of salt for the current K2."

Wayne -  How is the newer K2 going to rank in the retest? And what do =
you think of this Expanded Test Report and how it places the K2?=20
