It would be interesting to see an ISM neighborhood mesh network for broadcasting this kind of thing. With modern openly-licensed codecs you should be able to get decent music quality in 16kbps or less, so a half-duplex channel at 512kbps could carry 32 concurrent transmissions. With mesh nodes every 500 meters, you can use four nodes per square kilometer and spare the mobile nodes from spending battery on forwarding…
A long time ago I used an rtlsdr hooked up via usb-otg in order to track aircraft [1]. I'd be really interested in a minified version that didnt need the otg dongle. Or even a stand alone battery operated sdr that could be controlled with bluetooth? I dunno how big that market is, especially absent a network like you propose.

>Citation? I haven't heard anything about this and I work closely with telecom. It's what I've seen with some of my family that lives in smaller towns or rural areas. Some crappy company like CenturyLink buys up the infrastructure and then just lets it rot, but charges huge prices for phone service, higher than cellular service.

That's absolutely not the reason laws like that exist, unless you consider the neglected elderly who are ignored in places like hospice care facilities as having been 'manipulated'.
I think that's a grossly overbroad definition of the phrase.
Re: Pirate Act: what the law says and how it threatens pirate radio stations
#74There is an interesting story about the high power side of broadcasting. There was a station in the US, WLW that was 500 kW. This one station reached almost the entire country. The FCC finally limited the maximum power to 50 kW. Mexico had no such restriction, so "border blasters" appeared- high power stations on the boarder transmitting into the US. They ran ads, made money and had huge audiences. Most famous is Wol…

NPR argues that the proposed changes would unreasonably burden its member stations by requiring them to resolve LPFM interference problems. Adoption of the new FCC rules also would jeopardize the extensive network of translators that pubradio stations have built with federal assistance and would upend the commission’s longstanding spectrum policies favoring full-power broadcasters, according to NPR.
> “It may be one thing to ‘squeeze in’ secondary low-power facilities into a mature broadcast service,” NPR said, referring to the commission’s original plan for LPFM, “[but] it is quite another to reverse decades of commission policy and rules favoring higher-powered broadcast facilities by elevating LPFM stations to co-equal status with full power stations.”
> “The laws of physics have not changed, and a system of full-power broadcast stations serves many more listeners with less interference compared to low-power broadcasting,” NPR wrote.
> “We know there are not a lot of low-power stations out there in relation to how many could be if third-adjacency protections were lifted,” Riksen said. “We are really concerned about how many would come into creation when third-power adjacencies are eliminated entirely.”

Was getting in compliance too burdensome for them? For every well-behaved pirate, there’d be many ill-mannered pirates if you didn’t seize their operations.
1: being in compliance requires lots of money -> lots of money requires advertising -> advertising to be effective requires finding as many listeners as possible -> finding most listeners requires broadcasting trash -> bye bye small local station broadcasting interesting stuff. If there was a way to be in compliance without shelling out loads of money that would be awesome and we'd see pretty much every station becom…

It is harder to track who's listening to which FM station and might be useful if your internet is being blocked or censored

> I think radio is a lot like landline telephones: it's "dying", but it's taking a long time because there's a bunch of dinosaurs who still use it and won't quit until they're dead. I would consider actively switching if there were an alternative that was strictly better. Something with the quality of at least HD radio and the reliability and accessibility of FM radio, for instance.
SiriusXM?
I tried out SiriusXM when I got my new car, because they had a free 6-month trial. It was truly awful (even in a car, which doesn't exactly have a great environment for listening to music), so I quickly gave up on it.

Sorry, no, that doesn't qualify. The sound quality on SiriusXM is abysmal; it's something like a 32kbps bitrate. FM radio has far better fidelity.

It was truly awful (even in a car, which doesn't exactly have a great environment for listening to music), so I quickly gave up on it.
I thought you were kidding though, so I looked it up, and Wikipedia[0] confirms it:
> Each two-carrier group broadcast 100 8-kilobit-per-second streams in approximately 4 MHz of radio spectrum. These streams were combined using a patented process to form a variable number of channels using a variety of bitrates. Bandwidth is separated into segments of 4-kilobit-per-second virtual "streams" which are combined to form audio and data "channels" of varying bitrates from 4 to 64 kilobits-per-second.
Wow. I thought they just used satellite internet and streamed from their servers.

Years ago, I would have loved a good prog station. It would have been similar to a good pirate station "back in the day", or even like a lot of FM stations were back in the late 60s/early 70s. But I've long developed my own interests and moods over decades and I find it hard to want to listen to someone else making selections for me. Especially as I prefer listening to older music and I'm much less prog-exclusive tha…

>We get the leftover bits for arbitrary consumer transmission, the good parts are spoken for by corporations with deep pockets. Actually, no. Check out a chart of the usage of the radio spectrum in the US, and you'll find a shockingly huge amount of it is reserved for the military.
Fair enough. The deep pocketed corporations do still get preference over little people though, even if Big Daddy Government gets his slice first.
The solution, to me, is simple: if the little people want to be able to do more with the radio waves, they need to get the government to release some bands to them for amateur or low-power use, instead of expecting everyone to cram anything and everything into the 2.4GHz band. There's a huge amount of spectrum out there, but we're not allowed to use it because it's reserved for military radios. The military doesn't need to control the vast majority of the spectrum; it's not like they're exchanging vast quantities of data with it, the way we civilians do with our phones.
