Just curious, does the hardware within the Brax3 support what’s needed to be able to receive FM HD Radio? Is that something that the built-in FM Radio app, or some other open source FM app, does or might one day support? In particular, I’m interested in being able to listen to secondary “multicast” channels (HD-2 or HD-3) besides the main one.
Not a huge deal one way or the other, it’s not like it’s the main reason I have the device. Just wondering if it’s a thing that can be done, and if not, then whether the current impediments are due to hardware, software, or intellectual property licensing.
Those should be supported I believe. Not able to test at the moment as there are no HD radio frequencies supported where I currently am. Have you tried connecting to one?
I can get the radio stations near me load and clear (sometimes varying depending on how I’m holding or orienting the plugged-in headphone wire, reasonably), but no indication that I can see whether it’s using HD, nor a way to switch to the secondary channels. I’m just using the built-in FM Radio app though, and maybe I’m not looking in the right place?
Search the national frequency map for digital radio in your area and tune there. On their website you’ll find information on how many channels to expect etc.
Yes, if I go to https://hdradio.com/stations/ using zip code 01702 (which is near where I am), it lists several stations in the Boston-to-Worcester area that I should be able to get with an HD radio receiver. And I can tune the frequencies, and hear the main station, but no indication of being HD and no way to get to the -2 and -3 channels that I can find.
It seems that there are also different standards around the world and maybe even if it works it’s for Europe or other places. All the information concerns digital tuners as separate devices.
We have lots of HD radio stations here! The FM Radio app displays the song and artist being played just like the HD Radio receivers do. I think that’s the only way to know if a radio station is broadcasting in HD.
Yeah, that’s from RDS, a different set of digital data that gets sent along. HD Radio is something different, and includes a digital version of the main audio, as well as (for some stations) additional audio stations.
