KDFC 89.9 Livermore

radio11 said:
The transmitter has been silent for 3 days, but several tuner's meters show good signal strength. How is that possible?

Let's make a correction here, though it's one the average radio listener probably wouldn't have known. KDFC is located at 90.3 mHz and is licensed to San Francisco. KDFL, which simulcasts the programming of KDFC, is licensed to Livermore and is located at 89.9 mHz. My guess? Unless KDFC's main San Francisco transmitter is also down, there is a broken link between KDFC and KDFL. I'll let those who more than I do (if they choose) say what kind of link that most likely is.

Also, both stations are owned by the University of Southern California (USC, the owners of KUSC in Los Angeles) so any inquiries should go there.

its very likely transmitters like this are fed with a igh quality IP Feed using hardware liek a barix or comrex.....
 
They are now aware and will investigate.

they have a wireless ISP AND Starlink at the KDFC site so one should pick up when the other drops, but something went bust, clearly
 
The audio has come up within the last hour. I hope they've also fixed the intermittent stuttering that has plagued the signal for months. Is this sort of reliability what one should expect with a translator?

its not a translator, its a station.

As i said, its being delivered via IP using a wireless isp and starlink as a backup..... and the internet is the issue. theyre need to stablize the internet

Exactly my thought. Unless they don't want multiple ID's cluttering things up at the top of the hour.

That may be it. Because i think each station IDs individually and if The livermore station picked up the mothership, iut probably has more than one id on it

CTO tells me its because its far enough away in livermore that they wouldnt get a quality enough signal 24/7

There are real terrain problems out here. They might be better off aiming an antenna at the 104.9 signal. But even there they'd need the antenna a few hundred feet up the nearest mountain to insure clean reception, and that's a lot of coax cable to run.

and we know classical fans want a clean/clear signal or thatll prompt issues......

I can vouch that of all the stations that can be received where I live, 104.9 is the best. Clean stereo, wide bandwidth. The music sparkles. Most of the others either have too much processing or objectionable amounts of multipath (or both).
 
In a website pop-up, Classical California is finally acknowledging the signal problem in Livermore. Stuttering is almost constant, though sometimes less obvious.

Regarding 104.9, I think it is the only one that's HD.

Have you ever thought to chime in directly to the station with an email?

I've sent several emails, with rarely a response. It's annoying to a financial supporter.

interestiong.. i got a response within hours from the COO/CTO. Who are you emailing and what are you saying?
