Here is how I achieved great AM audio on 11m using a ham radio consisted of the following setup (This was back in 2007-2008):
~Kenwood TS-850SAT (balanced modulator input mod) I bought this radio from ghettoway driver from southern cali
~Blue Kiwi Microphone ($1,999 retail) (I tried over 20 mics, this did it for me) I also used the blue pop filter on it and it was mounted to a audio technica stand and shock mount.
~Mbox2 Pro w/certain plug-ins (ProTools A/D-D/A interface, now you can do pretty much anything you want to your audio signal for maximum fine tuning, heck even add echo and beeps from the protools plug-ins and other audio file insertions on the air if you wanted too, I had a blast using this, I remember the 12AX7 plugin gave me that tube distortion sound like you get with a browning or tram cranked up and fooled everyone on the air, they thought I was on a boat anchor when I was using a kenwood 850sat, lol)
~W2IHY IBox (for matching the mbox2 pro to kenwood 850sat line input)
~Heil footswitch for PTT (cool, when I first used it for this setup, it reminded me of using a Tram D201 or keying up a large amplifier), however for long keydowns, not cool, foot got tired and would sometimes let up, so I also rigged up another switching arrangement using a toggle switch, in case I wanted to get long winded and lock it down).
If I did it over today I would use the Flex SDR-1000 100w model with opened software for 11m (cheaper than kenwood,more audio bandwidth capability than kenwood, better receiver than kenwood and a ton of other things) and a bunch of hours getting it all setup and fine tuned right, but this would be a optimal route/pathway to go for high end audio on the air (AM or SSB) for not alot of money (you can substitute the expensive blue kiwi mic for a lower end model for a couple hundred dollars or less). A system like this today using a flex 1000 $500, mbox2 $~150, blue or similar style of mic $50-300+, etc would not be expensive, around a grand or so to build something like this today, and assuming you got a computer that will work with the flex and the pro-tools software, and most of all, the time to get it all setup right. It would look good on a 42-50" screen.
The best part is the mbox2 pro (pro-tools w/plug-ins) eliminates a whole audio rack of conventional gear and all the extra connections, extra cables etc (RFI) and simplifies the audio chain tremendously. All the audio processing is done in the digital domain. You get more audio adjustment capabilities using pro-tools with the plug-ins, it took me hours to learn it and get it setup right the first time out.
