HD Radio’s History of Innovation and Future of Growth

So, is HD radio too little too late? I actually thought about buying an HD transmitter.
We will see just exactly where HD Radio will be in 2030. Most people do believe that there is a future in HD Radio, with all the other platforms that radio uses it’s possible that HD Radio could do fairly well, as another choice for the listeners. The true test will be time, as new vehicles are sold that means more HD Radios in those new vehicles and more exposure to the listeners. I personally look back at where HD Radio was in 2010 and see where it’s at today and see that the growth is slow, but it’s growing and now with the possibility of AM stations allowed to go all digital it’s possible it could work, but again time will tell.

There aren't that many C-Quam stations around. Here's a list from Wikipedia:

WXYG/540: Sauk Rapids, MN
CFCB/570: Corner Brook, NL
CFCO/630: Chatham, Ontario (covering SW Ontario, Eastern Michigan and Northern Ohio)
WNMB/900: North Myrtle Beach, South Carolina
WBLQ/1230: Westerly, Rhode Island
WIRY/1340: Plattsburgh, New York
WAXB/850: Ridgefield Connecticut
WYLD-AM/940: New Orleans, Louisiana
WLAD/800: Danbury, Connecticut

I don't know how up to date it is.
 
I have heard that, at one time, WLS (890) was running their CQUAM exciter at night. Even though its a mono program. Go figure.
I'll pull out my old CQUAM receiver tonight and check it out.

You can add KBPS/1450: Portland, Oregon. It's been owned and operated by the Portland Public Schools since 1923!

WXYG 540 Sauk Rapids is a great station. I stream “The Goat 540“ a lot, they do a vintage classic rock format. A great listen indeed. You might want to check out the AM stereo website www.amstereo.org, they could have an updated list of stations.
 
The only CQUAM station I could receive last night was WJXL (1010) Jacksonville FLA CBS Sportsradio. They run 30KW at night. And, yes, I could hear the cursed platform motion in my headphones. It was nostalgic to see the amber led glowing again!

Many years ago, I was walking my dog and listening to KCJJ 1630 on my Sony SRF-42. The station was playing The Stereo MC's "Connected" The platform motion of their AM stereo, along with the platform motion of the SONG itself was just plain awesome.
 
WLS didn't decode on my Cquam receiver last night so I don't think they are running it anymore.
It could be that WJXL Jacksonville doesn't even know that it's on. It may be enabled, in the default mode, after a power interruption.
One station I thought should run Cquam is WSM (650) Nashville. They are primarily a country music station and carry the Grand Old Opry, at night. And they have good coverage, particularly in the southeast.

WSM did run C-Quam in the 1990's.
 
Muzak used to use SCA's quite a bit for subscription background music. Once the local flower shop signed up, the local rep would deliver a tuner to connect into their overhead PA system.
Muzak was initially delivered via ETs and telephone lines from a franchise holder's ET. After tape came in they put their library on tape for delivery. Which made possible smaller more local franchise areas. They began delivery by SCA in 1956 but telephone wire delivery remained pretty standard through much of the 60s. I should mention that there were a few FM stations who delivered Muzak to clients in the 50s over the air on their main band. But the FCC discouraged this. Experiments in satellite transmission they made from the mid 1970s but did not begin switching to satellite until 1980. There were once commercial radios available on which you could receive the standard SCA frequencies but the authorities clamped down on those manufacturers eventually and that came to an end. My mother had one in the 1980s on which she liked to tune in to the local police band.
