I've been searching the internet for days trying to find a product that can do what HD HomeRun does but for radio, and there's almost nothing.
There are some professional products intended for monitoring broadcasts, like https://www.axeltechnology.com/fm-re-br ... -receiver/ and https://www.stream-labs.com/products/de ... ultituner/ but these are well out of the price range of consumers. They also don't integrate with anything consumer, and have lots of features a consumer would not need.
I think it would be great if SiliconDust either: created a radio equivalent of HDHomeRun, added radio tuning capabilities to a future HDHomeRun model, or created future HDHomeRun's with the option to install an expansion card that adds radio capabilities.
From an amateur search online, it looks like the radio tuner chipset itself would be $20 or less, based on STElectronics chips prices.
According to their page listing radio tuner chips:
TDA7707 (single chip fully integrated) and STA710 (for SDR applications) have dual radio tuners that support AM, FM, DAB, DRM, and AM/FM HD Radio.
The TDA7707 is paired with either an STA660 for DAB/DAB+/DMB-A decoding (DMB is used in South Korea), an STA660DRM for Digital Radio Mondiale (DRM) decoding (and possibly also DAB/DAB+/DMB-A), an STA680 for HD Radio 1.5 decoding, or an STA680M for HD Radio 1.5 decoding with multiple antenna support.
The STA680 is around $11 and the TDA7707 looks to be around $3-$12.
NXP makes the TEF6686 which is apparently a drop-in replacement for the TDA7786. The TEF6686 seems to be used in a ton of handheld radios, in addition to head units; it seems to date back to at least 2017, with the TDA7707 dating back to at least 2014. So NXP seems like another potential chip manufacturer.
From my perspective, new radios are more common in vehicles than anywhere else, so a chipset created for vehicular applications should have the latest and best technology.
How about network radio streaming?
Re: How about network radio streaming?
HD Radio has licensing terms that are incompatible with an HDHomeRun-type product. The lack of available program guide data for most radio broadcasts would prevent it from being used with our existing DVR structure, and without recording support there isn't much point.
