I had only cursory knowledge about HD Radio until I got a new car. Since then, I found quite a few digital sub-channels that play more interesting, less mainstream content and have fewer ads.
When the coronavirus hit, and I stopped driving to office every day, I switched to listening to these on my phone or computer, but not all of them are available online. So I decided to buy a dedicated portable radio. Just got it yesterday and now I am having a long-forgotten fun of listening to broadcast radio.
What is your experience with HD Radio?
