FM "HD Radio" signal through DS DAC

dac

#1

Is it conceivable to put a terrestrial radio signal through the DS DAC, for those of us who live in remote rural areas that do not anticipate high speed home internet service in the foreseeable future?


#2

Radio is analog…


#3

I understand. Still, today’s FM signal carries a digital component capable of being decoded by an appropriate HD receiver. I would welcome decoding that digital component carried by the FM signal through the DS DAC for the reason detailed above.

I should add that what is suggested here may warrant creation of a new device for PS Audio’s rural customers. I assume–likely incorrectly–that many, globally, do not have access to high-speed streaming at home.

FM Radio > Amplifier. No DAC required.


#6

True. But I’d like to lend the benefits of the DS DAC to the “HD Radio” digital signal.


#7

Sure, you just need a HD radio with optical output, not through bridge, like this one for example. It’s discontinued, I don’t HD radio ever took off except in car head units.

Current model with both Optical Digital SPDIF or Digital Coaxial Outputs

Thank you SO much! I will try this.

You’re very welcome. I have HDRadio in my 16 year old truck and it makes a significant difference to the quality of radio as I’m sure you experienced. No, it’s not 24 bit/192kHz but its fine for the truck.

I would expect Ted’s magic code will process the signal quite nicely. I have a BHK with unused inputs but I prefer everything processed through my fan-less Roon Core + HQPe > IS2 > DS.

I hope Roon will someday add inputs from USB or other perhaps I’ll get one of these radios.

Concerning radio, for the audiophile, I found this:

^ For $3,500 I bet even the political ads will sound great on that!
This message approved by Pb.

Edit: my mistake, the model you found is only $1,200! Huh. That’s not bad, actually. If only there was a radio station in my area I could stand listening to for more than 10 minutes.


#13

Agreed. I would think the <$200 even with a few quirks would be adequate. HD radio approaches CD quality, no need to over kill it.


#14

Agreed. But this is an alternative for those interested in overkill! :grin:
