Hello. The scope of delivery includes a DAB/FM antenna - a so-called "throw antenna", a plug cable with a cable of around 1 metre, which is simply laid out.
Basically, the radios are only equipped with receivers and cannot transmit. There may be a few that can also transmit.
Regarding the HomePod, it has the following audio sources:
- Apple Music
- iTunes music purchases
- iCloud music library with an Apple Music or iTunes Match subscription
- Third-party music services6
- Apple Music Radio or episodes on-demand
- Apple Podcasts
- Latest news
- Enhanced room sounds
- Stream other content via AirPlay to HomePod from iPhone, iPad, Apple TV and Mac
Therefore, it will most likely not be possible for a radio to stream to the HomePod. Since Apple itself only specifies iPhone, iPad, Apple TV and Mac for Airplay.
