106.9 in San Francisco. :sneaky:

I know of one recent example of a religious, um, conversion, which was another swap, in Des Moines, where Iowa Catholic Radio and a Spanish-language broadcaster swapped AM and FM stations, with the commercial broadcaster ending up with 1150, the former KWKY. I could think of a couple of other examples, but I'll hold off because this has been enough of a runaway thread already.

Regarding KCBS's coverage:

The directional patterns, whether day or night, favor the SSE, more so at night but daytime coverage also does not go as far north as it does south. You can't get it in Eureka but you can get it in Paso Robles.
Yes, but David was specifically talking about the Metropolitan Survey Area, which (I think) stops well short of Eureka—-like a shade north of Santa Rosa?
 
But why compare it to KNBR? I fail to see how listening to Giants' game would conflict with listening to conservative radio.

Not a lot of people listen to two radios at once. If a significant percentage of KSFO listeners are tuning in Giants games on KNBR that’s three hours of listening every game day.

Not sure I buy the theory that the Giants alone are taking TSL from KSFO, but the drop did coincide with the beginning of baseball season.

And by the time most Giants' games start, the afternoon drive is well over. I'm just not understanding how KNBR is responsible for KSFO's demise.

Demise is too strong a word.
 
Am I wrong? Does the market not end around Santa Rosa? Is 740’s nighttime null so pronounced that it can’t make it 27 miles?
740's nighttime signal reaches well past Santa Rosa pretty well in my experience. It gets a bit iffy past Cloverdale, but it remains very listenable all the way to Ukiah.

Once I head east toward Lake County, though, the signal becomes mediocre rather quickly, likely due to the more mountainous terrain. It's almost like the places directly in line with the towers (basically a mile or so on either side of the 101 corridor) have the best reception, perhaps because most of that distance is basically valley floor with mountains on either side.

Yes, as to Santa Rosa. But 740 protects the entire Canadian border and the signal to the north is not totally gone, but very restricted and does not theoretically have a 10 mV/m over the wine country at night.

Yes, it "reaches" but it is not at a level that generates solid listening. Average folks won't listen to a station that has noise, static or fades out when driving under a power line.
 
If I remember correctly, KCBS had to protect a 740 in Toronto… CBL
It protects the whole Canadian border. That includes CBL and CBX in Edmonton... and even Newfoundland. Whether Canadian stations are operating or not, the international protection is still in effect.
 
And sort of by definition, if you have a powerful station that has to have one deep null, as 740 must toward Canada, you want to put it as far toward the null direction as possible so the deep null stays outside the market (in this case, up to Santa Rosa and beyond) and all your power is directed back into the market.

KCBS has been fairly lucky in that the site it chose in 1949-50 has remained at the edge of the market and there hasn't been significant sprawl into its null. Plenty of lesser class B stations (all our 5 kW DA-N signals in Rochester!) from the 1940s have been outgrown by market sprawl.

As for religious FMs returning to secular, it's not just 106.9 in SF - that happened to Family's big FMs in Sacramento, San Diego, Philly, Annapolis/DC and NYC/Newark, too. And the old KFSG-FM in LA.

That wasn't clear, but I'm not going to litigate it.

Thus spake @davideduardo :
Whatever your criteria for usable signals may be, neither 560 nor 610 cover the entire MSA adequately. Even 740 is deficient to the north...

Would it include Mendocino County?

The Neilsen map shows the MSA ending at the Sonoma/Mendocino county line (San Francisco MSA in red).

If you're on Highway 101, the line is just north of Cloverdale. That's 60 miles from 740's Novato transmitter site and David's assertion makes a lot more sense, especially on night pattern.

Arguing about the coverage of a station that this thread isn't about.

That's what happens when someone mentions their shock that "one of the five best signals in the market" hasn't found a buyer. The other four stations are gonna get mentioned.

Then David raised the issue about KCBS' coverage, I misunderstood the northern MSA boundary by 30 miles and here we are.

Oh, yeah, and there's the whole 610 thing, too.

From 7 p.m. to 10? I wouldn't think a lot of people would be listening to talk radio in that time slot. Most Giant games start between 6:45 - 7:05. Warriors' games are 2.5 hours long. Does that mean 95.7 The Game is also drawing away listeners from KSFO? :unsure:

It ends at Sonoma County to the north. For the "spectators" who are not familiar with ratings technology, Nielsen almost always measure full counties. They do not measure just cities, though.

There are a couple of exceptions where a county is split due to adjacency to other markets. The most southwestern county of CT splits with part in the NYC market, and part in the Bridgeport market...

In the Southwest, Riverside County has part in the Riverside-San Bernardino market, part in the Palm Springs market and the rest in no rated market. That is because that county is as big as some entire states in the Northeast!

So far this season, 27 Giants games have had first pitch times of 6:45 or later. Even if you include the seven games that started at 6:40, that's 34 games.

40 have been day games (start times before 5:00 p.m.). Of those, 38 have been before 4:00 p.m. and 34 have had first pitch prior to 3:00 p.m. In fact, today's game hosting Philadelphia began at 12:45.

Most Warriors games this past season were, in fact, night games. Only 18 of the 83 regular season games had tipoffs before 5:00 p.m. Pacific.




I hate to be that guy, @Street Novelist , but this is twice in a row where using the same device you use to make "from memory" posts could be used to look up the facts first and save us both some time.

You took that completely out of context. The majority of home games start at 7:05-7:15, now 6:45 since Manfred wants games ending earlier. Of course road games outside of the pacific time zone start earlier. Do you know why that is? And yes, Michael, today's home game started at 12:45. I hate to be that guy, but without using a search engine to give you the answer, can you tell me why it was an afternoon game?
