Yep, there is such a thing, which I encountered today, simulcasting KSFO. Audio was, much to my surprise, in both channels instead of just the right channel.

91.1 92.7 94.1 95.7 104.5 doesn't have HD Signals on. I'm not sure about others since I can't pick up their HD signals.
KNBR-FM doesn't broadcast in HD. Nor does KGMZ. Both are in mono, too.
Based on my experiences overnight (~2am) and a half hour ago, I suspect KCSM either had their HD off or was completely off the air. I was receiving 90.9 KXJZ from Sacramento absolutely clear, in glorious stereo, no HD sideband hash. I often get the station, but KCSM usually destroys KXJZ's stereo here (Redwood City hills).91.1 KCSM HD1 Jazz
It's on this morning, though the station ID is given as "HD", as it has been for some time.Based on my experiences overnight (~2am) and a half hour ago, I suspect KCSM either had their HD off or was completely off the air.

KNBR-FM hasn't run stereo since the switchover from KFOG. See photos - if there is an HD signal, this radio will force locking onto that signal. Radio Locator might as well be a daily horoscope as far as I'm concerned.Interesting, my car radio tells me they do as well as Radio Locator.




Will the addition of an HD2 signal lead to significant long-term ratings for KSFO, or will it be an extra cost with little return? KSFO has not had a truly local show since Sussman retired (A&G don't count since they're based in Sacramento and are syndicated all around the nation).
A lot of factors involved: Concentration of media ownership, corporate media owners not wanting to spend a lot of money on programming, high cost of living, and competition with the Internet.SF BA used to be a radio hotbed. Really sad what it is now.
OTOH, is KRBQ now owned by Arby's?
Shouldn't make a difference except for legal IDs. All the programming is coming out of downtown San Francisco anywayCan anyone fact-check the claim on Wikipedia that 107.7 HD2 used to have KNBR (as in 680 not 1050)? I'm surprised 1050 didn't get an FM HD2 simulcast on 107.7 given both stations are licensed to San Mateo.
Minor expense since the HD facility was already there, and it might get a few extra in-car listeners, since cars are where most HD receivers are these days, but not much effect otherwise.Will the addition of an HD2 signal lead to significant long-term ratings for KSFO, or will it be an extra cost with little return?
Credit where it's due. It was really @e-dawg and @Mark Roberts who compiled the list, all I did was clean up the formatting so future readers would have less difficulty following it. In order for me to even hear any HD's, I have to steal my wife's Prius. My car's radio doesn't have HD and I don't own any table-top HD radios. (I can make you a deal on a Sony Walkman SRF-42 with AMax stereo and lots of dust.Paraphrasing from
@Weiserguy's list:
While the SRF-42 was one of the few true AMAX receivers, it really was kind of an awful radio. It was hard to tune and the FM side of it was even worse than the typical Sony FM Walkman of the late 1980s and 1990s. Pro tip - if you want a good Sony FM Walkman, go on eBay and find an SRF-40W, which was the first FM Walkman model (1981). They're much less prone to front-end overload than subsequent models and have good, but not exceptional, sensitivity. They appear to be relatively plentiful and not that expensive.Credit where it's due.

There was more interesting programming on the HD subchannels until recently, though in the vast majority of cases they were automated jukeboxes or satellite-fed formats. It's only in the last few months that many of the subchannels have done dark, in what's been speculated as a cost-cutting move by the various group owners -- eliminating unnecessary licensing fees and such. I wouldn't be surprised if it's all gone by the end of the year, except where a third party is paying to lease an HD2 or HD3, or they're using one to feed a translator.
