We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
We listen to this station regularly here in Chicago. Streaming throughout the house into our Sonos wireless system but can also be fed into my good old 1980's room sized lung-crushing speakers if the spirit moves me.
They break the day into programs and keep them available for streaming for seven days. There are lots and lots of field-recorded concerts, some broadcast live. There is lots of talky stuff, too, for those who like that sort of thing (Radio 3 bills itself as the arts and classical music station). Also live broadcasts of Met operas, as well as rebroadcasts of UK opera companies, for those who like THAT sort of thing (and who doesn't?). The announcers speak a curious sort of English, but perfectly understandable. You will never hear any bad news about the BBC on Radio 3, so there's that.
Lots of singing, a British tradition, both small and large scale - something that our local, govt station has some sort of rule against (except for opera arias during pledge breaks). My favorite shows are Lunchtime Concert (chamber music) at noon M-F, and the Early Music Show on Sundays (used to be four hours per week).
There are two ways to view/listen: one through the link above and another through the iPlayer APP. Their website is a nightmare to navigate as are most these days, but worth it. Brits have to pay something like $20 a month to listen to/watch BBC, but we get radio for free (for now). You need at least about 44 kilo-byte/sec internet speed to stream. I use Audacity to record and save lots of their programming (I didn't just say that).
As EarlW says -- using any cable like this.
The Apple "Airport express" will connect to your stereo to stream music from your computer to your stereo, but only music in your itunes library, so live-streams from radio stations are out.
The Orb has mixed reviews
The Roku will stream music using Plex software app on the PC, but that sounds a bit hacktastic for someone who just wants it to work.
It looks like physical audio cable from a PC, tablet, or phone is the reliable and foolproof way to go this month.
I've been hanging on to this article -- mentally, at least -- against the day when my husband and I finally get our household merging finished (it's been less than 3 years, and we're old, so we get some kind of pass on the time factor) and figure out how to set up our real sound systems, instead of relying on just external computer speakers.
