[Elecraft] Wider bandwidth while listening to AM SW on the KX3?

[George Danner]

Guys,
AM Broadcasting isn't your grandmother's AM radio of old.
Many years ago, along came NRSC and it's 10kHz brick-wall filter & modified 
preemphsis. NRSC recommendations do not include a requirement for the audio 
be flat to the limits of the filter but encourage the broadcaster to use the 
bandpass that is necessary for the program material - Best Engineering 
Practices. Possibly limiting the audio to 5 kHz or even lower for voice only 
programming (talk radio).
The FCC has adopted the NRSC specifications for the audio chain; but 
retained the occupied RF bandpass requirements.

I'm fully confident that Elecraft could create a mode that complies with the 
NRSC's recommend AM receiver practices to include limiting the bandpass, 
premphsis & the 10 kHz notch filter curves.
Those of us that do not use an Elecraft transceiver for AM Broadcast can 
probably find other firmware features that we would like to have higher on 
the software enhancement list.

This is quite true Don, however it should also be noted that the design 
parameters of interest to this discussion largely lie in software, which 
provides considerable flexibility in meeting the goals of both ham band and 
general coverage reception. This is of course one of the big advantages of 
adopting a Software Defined Radio architecture.
