My bench?? equipment is largely under construction after almost 30
years of limited building and construction. Once Dave found a flaw
on the little daughter board which he admitted I would likely have
never found (although a new board would have accomplished the same
thing), the rig has performed flawlessly for me.?? It will be part
of an ARES earthquake drill Tuesday night.?? I am now on my fourth
and fifth kits.?? I intend to continue.?? Hi Fi on a ham
communication circuit? Gimme a break! And, I don't mean of a Kit
Kat bar either!
4SQRP has done it again so far as I am concerned.

Is it good enough
the the AM regulars aren???t going to have a hissyfit about less
than superlative hi if audio???
That's not something I worry much about ;-)?? Whenever I check
in with a 5 or 10 watt AM rig they are usually so surprised they
don't make any remarks about audio quality.???? The electret mic
has a wide response and there's some filtering in the audio
preamp, so to get a sense of what it looks like I played some 8
kHz white noise into the mic while looking at the output
With 20 kHz span each horizontal division represents 2 kHz so
you can see the Nouveau 75 passband is filled to 4 kHz - I
suspect the roll-off on the low end is due to limitations in my
test method.?? But this shows good audio response in the 2 kHz
range that Bob Heil emphasizes is most important for
