that greek dude is now building DRM transmitters. of course i don't know where you would find the receiving equipment to listen to DRM.

Dream 1.6.25 or 1.10.6 for decoding
Tonight while listening to This Week in Law, a program from the TWiT Network about internet law, they kept saying "DRM". I was wondering, "Why are they talking about Digital Radio Mondiale?"
It turns out they were referring to "Digital Rights Management."
Wow that didn't last long. Says its no longer available. Maybe just that particular sale, though I'm sure they build more than one at a time and sell more than just one at a time.
They are a good company, very reliable and make excellent exciters.
The reception though. Having to run some software program and then feed your AM radio into the computer just to decode this is, well...rather pointless..considering the countless other sources of digital media at that same computer off the web.
I just don't see this getting anywhere here in the US, simply because it is not already in radios you can simply turn on and tune a dial, pick it up and automatically decode this DRM, or select it when indicating DRM is present.
Right now, radio in the US is using the IBOC system, which has been declared as the standard by the FCC. Sure Part 15 does not have to abide by this use of IBELCH standards and can transmit a DRM signal if we choose to do so.
Bigger problem, as I pointed out before, who's gonna pick it up with the current radios out there?
Who are you going to convince in the general public to go through the trouble of connecting an AM radio into their computer and run a decoding program to hear that DRM signal, oh and have the skill to build that little device to begin with, when the most complexity people wish to become entangled with when it comes to wires is simply plugging in the power cord and flipping a switch and hearing something.
Anything much beyond that and your stepping into the "specialty" realm, ie us "techie" or "geek" types who will put up with fiddling with cables and wires and running programs just to hear something off a terrestrial signal.
Unless the receiver manufacturers are going to incorporate the DRM chipset along side with the IBLOCH stuff, which I doubt but who knows, DRM will have a very hard time putting a pebble dent in the US radio arena.
The solution won't be for someone to start pumping out modified AM radios to decode this DRM. At least not yet. What will be needed, and this should have been done back in the 80's during the AM Stereo nonsense, is public awareness first, introducing this concept and providing demonstrations of it.
However, right now the public's attention is being divided up between choosing another bad to replace a current bad, and radio right now is least on their minds, except for us radio geeks who spend hours listening to static and crackles and pops reminiscing the younger days when the crackles and pops came from the cereal bowl after pouring in the milk.
This DRM could be something the NALPB can examine and perhaps be of help in getting it into the public radar. But again, unless joe or jane public can simply say to themselves, "hmm let me turn on my radio and see"...well you see the wee lil problem there eh?

on the first two posts.
Yeah I noticed that prior to posting but still felt like responding to it since someone else bumped it up! 😀
