Listening to CHKX 94.7MHz in HD Radio at the moment is NOT a good representation of HD radio and makes a massive case for what Ben has been after: an audio switching methodology to defeat the HD1 feed.
This is so reminiscent of times I was listening to DAB.
As I type, CHKX 94.7MHz has analogue FM. That's OK
HD1, no audio but song titles are there.
HD2, "wave.fm" sounds fine.
Had the HD1 feed been able to be bypassed, regular FM would have filled the gap. As it is now, KX-94.7 can NOT be enjoyed on an HD Radio receiver as designed.
I see as I continue to type, they're working on it, but still no audio on HD1.
Thus, they do seem to have a lot of teething problems keeping it going, just like DAB.
The 95,3FM HD signal appears to be stable however.
I've heard both systems sound great. But as I said earlier, when it goes wrong, man it goes very wrong, and digital doesn't lie.
EDIT: with silence on HD1 continuing, I just picked up the radio to see what was playing... you'll never believe this...
Song title: "Fix" by Chris Lane... (my sides are sore now... LOL)
