Hi Don,
Yeah, I've actually discovered that this is not very effective for the wider
filter bandwidths such as in SSB. I got them spot on in CW with the narrower
widths I use (1.40, .700, .400, .200) but in SSB I can't find the midpoint
very well at all.
I've decided, tho, to leave my K2 as-is
LS,
That method works, but it suffers from the fact that finding the actual
filter center frequency is difficult to do. As the filter width is
changed, the lower and upper skirts do not change at the same rate -
that is the main problem. Yes, you are correct that in 1999 tapping the
Hi all,
Not meaning to add to the wealth of info already on this topic, but I have a
specific question about the setting up your CW filters for the tonally
challenged article on the elecraft website.
Specifically, part of the instructions in it to read the BFO frequencies
