Music identifiers

Is it RDS? Does it stand for ... "Radio Display Service"? I'm talking about those FM stations where you can read the title and artist of each song as it is played.
So, that brings up this question, can it be done on AM stations? I realize most AM stations are talk, and may not feel a need to, but there are some music stations, or stations that play some music on AM, and I've never encountered one that shares this information. If AM stations can not do it from a technical perspective, please explain why to this person who is not an engineer.
 
From wikipedia " RDS, is a communications protocol standard for embedding small amounts of digital information in conventional FM radio broadcasts" .
 
To add further, FM may have SCA,that is Subsidiary Communications Authority. It transmits audio on FM subcarriers that may be used for various services, such as reading for the visually impaired, or backhaul from a remote. AM radio has no such subcarriers,
 
HD AM does that! (ducking & hiding)
There was some discussion about using the CQUAM 25 Hz to send really slow data to recievers. Guess it was way too slow.
 
The idea of moving the LPFM and all AM stations to the new band is interesting, but would listeners be willing to buy all-new radios to get it? Here's a question... like what was done for analog TV's that people didn't want to throw out, could "they" make converters for current radios so that they could pick up the AM stations on the new band?

There are a number of people who say the over-the-air radio industry is expiring. If that's the case, then wouldn't stations signing off for good open up the current band and make it less crowded?
My belief is until some radio stations of note completely shut down, then the talk of O.T.A. radio's demise is vastly premature.
 
They made FM receiver adapters for AM radios back in the 60s. I see no reason the same couldn't be done for a band move.
 
Probably true of many one-chip radios.

The point is "lack of radios" is not a valid objection to the proposal to expand FM into channels 5 and 6.

Radios that tune TV channels 5 & 6 (76 to 88 MHZ.) are common in Asia. Look at this radio from a Chinese manufacturer:

Check out this little gem-- The SONY SRF-A300.

It's actually MADE IN JAPAN, receives the Japanese FM band (76-88), and can even receive C-QUAM on the AM band. I own one, they're great! You have to order from Japan because they are not sold in the US.
 
Yes...the identifiers and certain operating constants are different, but otherwise the systems are identical and interchangeable.
 
I think the major problem with putting the AM band on ch 5/6 is that it won't have the benefits of skywave or huge daytime groundwave coverage.
I wouldn't want to lose these advantages of MW propogation.
But then, I'm one of those backward people who think music can sound better on AM than FM (as practiced).

If we changed the AM designation to ZM and relabeled all radios it would gain interest because it was new. New tide.

90 percent of Am stations stink and need to move to CH 5/6. old transmitters will be replaced. old processing. "old managers?"
 
When E-skip's in, from May through August & around December and January, stations in the old Ch 5-6 band will be pummeled by skip. As an old ex-dxer I had observed CH 5 being torn up for many hours with skip that never made it above 88 MHz.
