Not sure how I missed that. I just did a side by side comparison of the
ARRL CW spectral plots for both the K3 and the FTdx-5000, and there is
certainly a difference. 30db down from the peak appears to be +/- 350
Hz for the FTdx-5000, and about +/- 125 Hz for the K3 as best I could
determine from expanded views of the plots. 60 db down (still probably
about S2 for a S9+20 signal) appears to be about +/- 1.35 Khz for the
FTdx-5000 and about +/- 350 Hz for the K3.
Here's a thought ... if everyone owned a Yaesu the company wouldn't have
to worry about designing receivers with close-in BDR because nobody
could operate that close to each other anyway.
