[Elecraft] New: K3 tops the list

[Dave G4AON]

Guys

It's not rocket science to measure the performance of a receiver... All 
you need are a few items of relatively common test gear, calibrated to 
national standards if possible. The test procedure is given in some 
detail on the ARRL web site.

No "review" will be representative of all K3s, I've measured similar 3rd 
order dynamic range as do our German colleagues... That covers 
measurements on four different samples of a K3 - all can't be wrong. To 
put the K3 in perspective, in the March 2008 RSGB RadCom there is a 
review of the FT2000D by Peter Hart (G3SJX) which gives a 3rd order 
dynamic range of 67 dB at 2 KHz spacing... at least 30 dB worse than 
most K3 measurements.

Charlie,
I am sorry to hear that Rob Sherwood's K3 test was performed on a
rig that may or may not be representative off all K3's. It would have been
best if Elecraft had not done any work on it or made any adjustments to it
once it was built by you. Chances are what they did to it did not have any
affect on its performance but we will never know. I hope you will like your
#149 as much as I like my #148.
