Hi Henry:
It will do exactly as you described...perfect for viewing the nearby
part of the band. The SDR will show much more than 20Khz. I think
the
preselector in my a version was not very sharp, and the SDR was plenty
sensitive.
It takes very little coupling to make it work. I never did even take
the time to put in any active isolation..ie a FET isolator, and just
used a couple of twisted turns of wire around one of the tube leads to
the IF input filter. I can show the exact spot later when I get home
if
nec.
Think I used only a couple of twists and a 10pf blocking cap.
Curt
