I ran 10 kHz wide most of my pirate career. With the flavor of Cool Edit I had, you could choose 50 or 75 uS settings. I went with 75 as it was the standard here. My outboard EQ/mixer was the old "WREC" board P.J. sold me. I used the Cool Edit EQ only for touching up the audio when I was doing the final mixdown.

Cool Edit was great for giving you nice tight pro sounding shows. Before that it was the old "turn and half" back of the cassette spool with your little finger and lot of praying you got it right. You could splice it, but if you ever had one give during production, you could be heard cussing for miles. You work hours and days to get halfway close on that final bit or set of songs, only to say "F##* it!" and head out the door with a half-assed show.

It was still a boatload of fun once you got on the air, despite the trouble.

The processing we have now is set for 12.5 KHz, but will allow up to 15KHz if we want.  12-13 KHz seems to be a good compromise between musical content and occupied bandwidth.  10 KHz to me with modern music just sounds too restricted, and 5 KHz is just unacceptable.

These are just my opinions, and are subject to change :)

Unfortunately, unless signal strengths are excellent I end up using about a 3 kHz bandwidth. I suspect most others use about the same. Otherwise the resulting audio becomes unbearable to listen to after a few seconds.

redhat:
I suspect several things are in play here as I noticed similar things when receiving recordings in the early days.  Prior to the SDR era, most guys were listening using communications receivers or ham transceivers with very limited AM bandwidth, and you get used to listening to audio in that mode.  I'm a broadcast engineer and I am used to monitoring signals using high level demodulators with unrestricted audio.  I remember an experience I had when rebuilding a studio for a small AM station in the midwest.  We had finished work for the day and I was sitting in the corner of the control room and the speakers were monitoring the off air wideband inovonics monitor we had installed in the rack room.  I was struck by how good the signal sounded, much better than any AM radio I had previously heard.  In the industry I also sometimes hear engineers lament about how much better AM sounded before the bandwidth limit rules were imposed by NRSC in the late 80's.

Point being I will suffer through a lot of noise and static to hear the wideband audio of a station to the point that it hurts my ears.  Running a little more de-emphasis than usual can greatly assist in this regard.  In the era of Kiwi's, if it sounds like crap in my backyard, I just go hunting elsewhere.

P.S. Sorry for hijacking your thread, Chris :)

Josh:
A lot of the analog rigs will only pass about 10 to 15Kc, so there's that.
