I wish that Jon could actually experience this and see that his
thinking 'outside the box' isn't going to be an automatic revelation
that 80 years of radio has simply overlooked.
Thirty minutes on the bench could save 'light-hours' of ramblings.


I don't follow your reasoning on this, what is Jon going to learn in
"Thirty minutes on the bench"? I would venture next to nothing? Thirty
weeks on the bench might be more like it, and even then there won't be
time to explore all avenues. As far as 80 years of radio go, Jon's
constraints are different than might have existed when tube radios were a
mass application, he may be able to make different tradeoffs than were
practical then.

Don't be silly just for the sake of being a 'devils advocate', John. If
Jon can achieve his plug-in TRF boards with any semblance of a $1.95
flea-market AA5 selectivity then I would be pleased.
What I haven't heard from Jon beyond musings that suggest that 80 years
of radio have missed his point is a bit of actual soldering on the bench
to make up these mythical circuits. At least Mr. Windbag No-Snip
Patrick appears to have walked the walk before but Jon is reluctant to
take your, my, Patrick's or anybody else's advice about how to meet his
goal...and at this stage seems to be fishing without good bait for
somebody who is in agreement.
Jon's "tradeoffs" are ultimately the clue. Once presented with the
facts and a million lines of newsgroup advice its time to go to the
bench and actually MAKE one of these panacea BCB BP filters. I strongly
suspect that this effort would clue Jon into some of the realities of
how things work and no amount of chatter from us could be of further
benefit other than our own wing flapping.
