KEXP Buys KREV

It’s very valuable with our regions crowded bands and the topology to remove multipathing. I’m just applauding KEXP for joining every broadcaster in our region in using the technology. That signal makes the biggest difference you’d ever imagine. I’ve experienced it first hand too often now.
As a former Bay Area resident (and frequent visitor), I'd 100% agree that HD helps reception. Real world example: in most valleys of Marin County, all the San Bruno sticks (and most Sutro ones too) have multipath when listening in analog. But when I listen on my HD car radio, audio is crystal-clear.

I realize many cars and virtually no home radios *have* HD capability, but that's a different topic.
 
Works good for removing multipath, but I would argue that it's not that great in a market with crowded bands. Xperi/Ibiquity pulled an interesting trick with bandwidth measurement to say that HD fits the bandwidth limitations of FCC part 73.317. But in reality it requires 400 KHz of occupied bandwidth on the FM band instead of 200. More here:


How does that mask in the diagram on page 7 show the sidebands down 30 db when the injection level can be as high as -10 db? Simple! You just set your spectrum analyzer to a narrow bandwidth for compliance measurement. Never mind that radios don't behave that way in the real world. But that train left the station long ago, and there are quite a few broadcasters who have lost coverage due to interference as a result of it.

Will it affect KEXP? Not likely. 92.9 is in Ukiah and 92.5 is in Sacramento. That one is in the clear.

I have a question about HD for anyone with actual, practical IBOC expertise.

Let's say I'm in a receiving location that's equidistant between two station pushing HD at the -10 db injection level, and the stations are two channels apart. (For argument's sake, 106.1 in San Francisco and 106.5 Sacramento. Assuming no terrain issues, I should be receiving their analog and HD signals at about the same strength. What happens with those HD sidebands? Assumedly, they arrive at approximately the same strength too, and the 106.3 sidebands should theoretically stomp all over each other. (If there's also a 106.9 running HD - which there is, KFRC - those should clobber each other too on 106.7.)

So do they cancel each other out and make those stations' HD services undecodable/unusable? You'd assume so, but I don't have any expertise beyond a SWAG.
 
Given the size of the transmitter required for their proposed new site, adding HD isn't that large of an expense. It's when you have a Class C that requires 30kW or more TPO where switching to HD gets really expensive.

They don’t step on each other. Instead, 106.3 would have IBOC side bands on the lower half and the upper half. There’s also the other side band.
 
Isn't the issue more about what happens on an analog radio?
I'm well aware of the effect of sidebands on an analog signal. (I don't think anyone -- except listeners -- really cared about the HD sidebands stomping on any analog signal on the first adjacents.) My question was about sidebands "banging" into each other and, effectively, creating "mutual assured destruction" to both stations' HD transmissions. From what @nd2023 wrote, it seems some engineer actually thought the problem through in advance.
 
Radiopaw said:
Will the mid-March swap be a simulcast?
That is the plan.

I think it'll work in SF as well as it's working in Seattle because the competition is similar. What exists in SF is a large group of people who no longer use radio because it doesn't speak to them anymore. KEXP just might speak to them, and bring them back to radio.

That's what's missing from the radio landscape. Everyone is chasing after the target demo. No one seems to be looking to grow the radio pie, and go after people who don't listen.
 
KREN has filed a STA to operate with reduced power and use a different antenna at Mt. Sutro.

Reduced Power Exhibit
On January 2, 2024, the Bankruptcy Estate of Golden State Broadcasting, LLC (“Golden State”), controlled by Michael W. Carmel, Esq., the Chapter 11 Trustee (“Trustee”) appointed by the bankruptcy court, and the licensee of KREV(FM), Alameda, California (Facility ID No. 36029, “KREV”), filed a notification that the minor change authorized by construction permit LMS File No. 0000232003 (the “Permit”) had been constructed in accordance with the Permit, and KREV commenced operation with those facilities under automatic program test authority on Friday, December 29, 2023.1 See LMS File No. 0004234618 (the “PTA Notification”).

Golden State also advised, see PTA Notification at Program Test Authority and Reduced Power Notification Exhibit, that the new facilities are using a temporary nondirectional antenna, mounted at the height authorized by the Permit, which due to issues during retuning for this use is operating at a reduced power, of approximately 300 watts effective radiated power (“ERP”) rather than the 790 watts ERP authorized by the Permit (so at approximately 38% of authorized ERP), as permitted by Section 73.1560(d) of the Commission’s Rules, 47 C.F.R. § 73.1560(d); since Golden State anticipates that this reduced power operation will continue for more than 30 days, Golden State will be filing a request for special temporary authority (“STA”) for the reduced power operation.
Golden State filed for the Permit on December 7, 2023, when the agreement for use of its licensed tower site was terminated effective as of December 31, 2023, and the parties were unable to reach mutually agreeable terms for an extension or a new agreement. After grant of the Permit on December 14, 2023, Golden State moved expeditiously to construct facilities in accordance with the Permit, and was able to complete construction on December 29, 2023; this allowed KREV to not go silent after December 31, 2023. While the new facilities are operating temporarily at a reduced power, the public interest would be served by the reduced power operation by allowing service to continue at a reduced power (rather than the station going silent). A permanent nondirectional antenna has been ordered, which should remedy the issue causing reduced power; the replacement of one nondirectional antenna with another nondirectional antenna is permissive under Section 73.1690(c)(1) of the Commission’s Rules.

Fascinating. I was wondering how this was working, under the terms of the court and the sale. Now I know.
 
So what is the final power operations and height going to be?

Or is this just filing to continue operations as is until their permanent antenna is here?

No doubt the trustee and KEXP are coordinating; it's in the best interest of both parties to do so.

The CP is for 790 watts at 275 meters - maximum height for class A stations at 6 kw is 100 meters, so the power levels have to be reduced accordingly if a higher site is used. This is the CP. What was most recently filed was a reduced power notification due to issues that occurred when the temporary antenna on Sutro was installed. That notification also stated that a request for an STA at reduced power is forthcoming.

But those demos are who advertisers want to reach. Advertisers pay the bills.

Seniors still love radio and would like to be catered to. The problem is; as you already know, those advertisers who might buy radio aren't interested in reaching Seniors.
 
I think what we were talking about in #169 is bringing back those who left when commercial AAA (KFOG) went away.
It will be interesting to see if this really comes to pass, or whether KEXP gains a somewhat different audience.

Before 2017, when KFOG ditched many of the features of its previous format and essentially became "Live 105 Lite"[1], the station had become stodgy. It was beloved by its aging base of listeners. The station's imaging was strong, and it skillfully used earlier forms of social media, giving "Fogheads" a sense of belonging to a community. But it increasingly was stuck in the past. It was becoming like KGO with music[2]. The one thing that managed to stay fresh was "10 @ 10" which, by its very nature, bent the boundaries of the format. Dave Morey, the voice of the station, had long retired, too. The station became too predictable and set in its ways. Cumulus tried to shake it up, but then the need to protect the KNBR money cow arose, and 104.5 became the frequency sacrified for that purpose.

The switch to KNBR-FM did gain some attention, often along the lines of pining for the fjords the way KFOG was, not what it had become in its last couple of years. In that, one could detect that the gray-ponytail crowd was wistful but had already moved on.

It seems to me that KEXP tries to appeal to a younger, more diverse audience. Probably the closest appeal in over-the-air radio in the Bay Area today would be the nightly DJ sets on KALW, but that isn't quite what KEXP does. KFOG also existed within the boundaries of consultancy and research [3]; I suspect KEXP isn't as tightly bound to such things.

Footnotes (because I've been overusing parentheses):

[1] This is not meant to denigrate a valiant effort to modernize the station. But it was trying to become a younger, alternative station while KITS was still around; admittedly Live 105 was in a decline in those days, but still, it was a head-to-head match that might have succeeded 10 years earlier, given enough time. Cumulus didn't have time and the overall context had changed.

[2] KGO also had its audience that loved the station, and would love the station until those listeners took their last breaths. But not enough newer, younger listeners were coming in. KFOG had the same problem. It's notable that Cumulus ended up with a couple of stations in the Bay Area that ended up with demographic dead-ends, i.e., it was a weakened cluster even before over-the-air radio's severe challenges of the last few years.

[3] Lee Abrams came up with the format; it was installed by General Electric. This makes it even more amazing that the station managed for decades to project the image of an independent broadcaster. In many ways, the KFOG imaging was better than the music.

It will be interesting to see what develops. For my part, I'm trying to avoid preconceived notions - if I still lived in the Bay Area, I might actually have given into some of those notions.
