I, too, want to see a complete unit capable of interfacing with the older Radio Systems' ATU. The world really needs another Part 15 C-QuAM transmitter like AspiSys's AXMAX-1. Personally, I don't have much time for experimenting with hardware. I like this idea, but I really need a complete solution for Part 15. In all honesty, despite a couple of negative reviews of the ASMAX-1, I'll probably buy the ASMAX-1 based on my experience with AspiSys' DRMAX-1.
A few months ago, I asked here about upgrading current monophonic Part 15 transmitters to AM stereo. I still think it's a smart move for both AM stereo and the designers of these Part 15 transmitters. HD-Radios are capable of decoding C-QuAM. Sodira is capable of decoding C-QuAM.
AM stereo is one of the great technological improvements that (mostly) slipped away because it wasn't taken seriously enough. It is good to see that at least a few part 15ers are keeping it in mind.
The great cross-over from a mono to a stereo world is still going on in many ways, and I guess it started when LP records went stereo.
I still have a Bert Kampfert record on Decca from 1960 with one channel out of phase. That happened when stereo was new and engineers were still learning the tricks.
For awhile record companies released both mono and stereo editions of their recordings, and eventually stereo became the only choice.
Mono records became yard sale stuff, until demand returned for older material that was never released in stereo.
A few record companies tried to re-release items from their mono archives with synthetic stereo, which took several different approaches. I have a Capitol record in Duo-phonic sound... I think they slightly delayed one channel giving the stereo listener a bit of "echo space," while if played in mono it sounded like a goofy echo.
Aphex came out with a neat Stereo Generator that took mono sound and created an artificial L - R signal giving a roomy quality to the sound, but it didn't know how to seperate instruments to their proper locations on stage. I liked the thing.
Attempts to give us more ears havn't seemed to last, like Quad and the more recent 5.1 Surround Sound, which is hell to mix-down to mono. The problem with these many-channel approaches is that they require the listener to stand still facing a given direction.
Of course if you're in a car, you'd better face a given direction.
