My point still holds in that nobody serious builds LCR filters for
auido (speaker crossovers exempted). His LCR filter IS in the audio
chain, not the IF.


Your comment that "nobody serious" is so off base as to be asiniine.
Dallas Lankford is clearly one of most serious DXers alive today.
Why not take a look at all the technical information at
http://www.kongsfjord.no/dl/dl.htm
before jumping to silly conclussions.

I've done (as in been paid for) filter design in telecom/datacom
applications, including elliptic filters, delay equalizers, etc. I know
of what I speak.

There is a leapfrog design on this page if you want to educate
yourself:

I give up, you win.
Only idoits and fools would bother to build any passive
AF fitlers. Please build all the active ELPAF filters your
heart desires. I made the mistake of assuming you where
a serious SWL.

I bet you would find the thought of building a clipper to limit
the AF level to a set of earphones with something as simple
as a couple of parallel 1N4004 diodes and a series resistor
so repulsive as to nearly make yo puke.

I can hear it now, "Oh My God, how simple."

I bet you could whip up a active limiter that would achieve
+/-0.0001dB clipping accuracy.

Too bad you make Cuhulin seem reasonable.

I can't PLONK you with Google beta, but I damn sure will ignore
your posts.

Hey, is idoit something like an idiot?

Your reaction is bizzare to say the least, but plonk away.
