A wide-band FM receiver will not detect a narrow
band FM transmission at all?

Or does it merely detect it less efficiently?

I believe that the wide band tuning is designed
for TV, currently AM/video and FM/audio. I do not
know if there is a way to force it into AM mode
for voice.

I suppose there may be a way to tap the AM/video
side and to feed it back into the audio stage, if
one could get the schematics, which I doubt!

It all may be trapped inside a proprietary IC and
it therefore may be impossible.

Neat series of devices Innovatek is releasing --
so many toys, so little time and money!
