Jerry: I don't know if you own a K3 or not but if you don't then you should invest in one before knocking the K3 down. The fact that Sherwood Engineering and others have found the K3 to surpass the receivers in those expensive radios like the IC-7800 and the FTDX-9000, should be enough proof of the performance of the K3. I have owned many different receivers/transceivers over my ham career and I honestly have not found anything yet to be the receiver in the K3. Just my 2 cents worth from Fern with K3 #412.
The high prices of the roofing filters for the K3 and optional filters for other rigs reminds me of a little history. Nevertheless, I find it especially disturbing having to pay these modern prices considering that the filters have apparently not been designed or chosen for good IMD performance or advantageous group delay characteristics. Also, some filters are reputed to have been defective. Of course, the filters may not be totally to blame for the mediocre front end performance of the K3 (compared with the professional-level performance that some of us had hoped for.)
