[Elecraft] [KX3] - KXFL3

[Geoffrey Downs]

Thanks Walter. I had forgotten that Rob Sherwood had tested it. Interesting. 
The dynamic range looks pretty good compared with other rigs even without 
the KXFL3. I don't have enough technical background to understand the 
significance of footnote v, though. Perhaps some knowledgeable person could 
explain?

Would anyone who has a KX3 without a KXFL3 care to comment on their 
experience?

Yes, it is possible to quantify it. See the measurements with and without 
the roofing filter here (you'll need to check the footnotes):
