The one I listen to is the 50,000 watt station in San Francisco, which has a decent signal down to central California (and beyond). I'm just an old radio nut. The first electronic kit I built was a shortwave radio.

But these days, they all either have their own apps or stream or both. I was using their youtube channel, mainly because it's way clearer, the local ads are not allow to play on YouTube (YAY) and so on, but I deem it a waste to be gulping video when the announcers are butt-ugly and I only want the sound anyway.
And there are "radio" apps that re-feed the various streams. Getting up to squelch "Kars for Kids" is good exercise. One needs to break computer sessions!!!
And, since there is only ONE classical station whose radio waves reach this spot, via a repeater that quits every time snow crushes its antenna, I basically do ALL my classical music listening over the internet. The classical switches to jazz from 7 to midnight, but it's not jazz that I care for. TBH, it sounds like lounge music to me, not REAL jazz (YMMV)
Favorites are
Classical California (basically KUSC, they merged with KDFC in the SF bay area). I use the app. (or the stream in the browser)
WQXR, I use their app or browse. Very often, the "Operavore" stream, or the main stream for non-opera stuff (also great)
WBJC in Baltimore. Great programming. A junior college, in fact. https://wbjc.com
I use the "alternate player" and that works for me.
On the internet, distance is a non-matter. Follow the mike jockeys in your favorite team(s) town.
