I would also be very interested in the answer to this question. I was surprised to see these BGC numbers for 6 meters. As a 6-meter SSB op who lives or dies with the summer VHF contests each year, where 40-over-S9 sporadic-E propagated signals are packed elbow-to-elbow on 50 MHz, this is a very important parameter!
Could Wayne or Eric or Lyle provide some insight into this? Would be very grateful. Hopefully this was just an aberration in the tested K3, or perhaps a typo, as has been previously mentioned. Also, I'd appreciate any feedback on the dynamic range degradation measured with the 1.8 kHz roofing filter. I have one I purchased recently but have not yet installed it. Was there a "bad batch"? How can I know?
