Being (until I got K2 #6065) an AM operator with all
homebrew stuff, I am very keen to know about the AM fidelity.

Besides roofing filters, I an curious what bandwidths are
available for AM reception, could the 15 kHz FM filter be used on AM?
About 6 and 4 kHz filters seem to be the most useful

I also cant wait to see the audio specs, or if there is a line
level audio output.

A sync detector on AM would be great, I never homebrewed
one of those...
