Added the HD-Radio tuner to the home theater system a little over a year ago.
Only to find that the tuners are flawed they lack venting or any heat sinks to keep the chips cooled down.
What happens after a very short time is the radio will no longer hold any HD signal for more than a few moments at a time before dropping signal completely and not reverting to standard signal like it is supposed to when a HD signal drops. Which once you are locked in it should not drop at all especially when your tuner is attached to an outdoor antenna that is 30+ ft high.
Most realize that there is a heating issue once they have this happen but is to late the damage is done cooling & heat sinks can’t repair damage already done they can only prevent heat damage.
Which left me to either re-purchase another HD-Radio Tuner and take it apart right away modify case add fans and also heat sinks before ever turning it on. Or simply just buy a SiriusXM Home tuner instead. Which does not have the overheating issues but will cost me a monthly fee.
There are only a few rack type HD-Radio tuners and all are made by 1 or 2 companies Sangean & Insignia there are a few different models but all have the same flaw. And both start at $150-$200.
There are a few different models each company makes one model has only analog output while the other supports both analog out and Optical SPDIF Output.
At $150 it should have the optical output anyhow.
HD-Radio not to be confused with Satellite radio they differ not only in hardware types but HD-Radio doesn’t cost you any monthly bills.
Sony does have a model that has outputs but is not a rack type tuner it has an alarm clock look or a modern boom box ipod dock.
As you can see this just isn’t something that will stack up in your home theater cleanly.
While the Insignia and Sangean models look similar but work in a rack setup.
What I decided was to not replace the HD-Radio at that cost to have to modify it and hope it lasts a few years to get my $200 worth.
I miss Howard Stern and the metal station the Polk Audio XRT12 was perfect it fits in a rack system and it only costs $60!
Sure a small monthly bill kind of sucks ass but it will work and not overheat and die in under or a little over the year mark.
