Re: fm sleuth ????

"Fatigue" seems to be a symptom of too much HF in the balance of frequencies reproduced. At least, that's what I read all over and experience myself. Often that "extra detail" is delivered by a boost in HF or by a corresponding decrease in mids/bass that may have masked some HF. So if that's your problem, consider treating that issue, and all this antenna conversation doesn't seem to me to be relevant to that.
I keep reading that extra circuitry adds extra distortion. Yep, that's the theory and I'm sure that you can demo it on a scope. However, it's not as simple as that always. How much distortion vs. how much increase in something that the individual listener finds pleasurable? How much of distortion masks something that the listener finds objectionable? This is psycho-acoustics as much as it is electronics UP TO A POINT.
I'm using a little cheap coax amp on my FM system. RS TV/FM directional antenna in an attic, then lots of cable (50' or so), then coax amp, then receiver. Yes, if the reception is grainy or otherwise not good the amp only amplifies the problem - more dbs more easily, but not greater clarity. The effect can sound worse. On the other hand, on all FM stations with good reception, that boost in db is a good thing to my ears. So the conventional wisdom about adding no extra circuitry, when delivered as an absolute, is suspect IMHO and IME.
Timbo, I'm curious about your chicken wire shielding deal. Can you explain this or post some sort of diagram?
