HD Radio Tuner Modifications

Netdewt · 26th February 2010, 09:18 PM

Really, the only two units available are the Sangean HDT-1/1X and the Sony XDR-F1HD. The 1X has a digital out. I have seen some modifications stuff on the net.

modified Sangean - $800

Have you guys tried these? Any modders out there? I'm especially interested in getting a digital out from the Sony? Ideas on how to hack it?

One answer I got via email:

Quote:

Have you or do you know of anyone who has been able to get the digital
signal from the tuner, so that it can be sent to a decent DAC? Or is it not
good enough to be worth trying?

Quote:

A digitized version of the audio of not available at the module level. There are pins inside the module on the chip for the purpose, but I don't know whether they are driven.

The DAC uses a huge oversampling factor to shape the quantization noise and push it outside the audible bandwidth. Why would you want to undo that?

Am I asking a stupid question?
