KOGO 600 No Longer Just 5,000 Watts

G

Gregg.

Did anyone discuss this? There's another thread talking about layoffs at KOGO. I checked the Wikipedia page and see KOGO has upgraded daytime power to 9,000 watts and nighttime power to 10,000 watts. It uses a 3-tower directional antenna day and night.

Did this power increase happen recently? KOGO actually goes up in power at night but only by 1,000 watts. Compare that to co-owned 760 KGB. Talk about going up, not down, in nighttime power. That station is 5,000 watts by day but 50,000 watts at night!

For the record, here is the information for both stations on @Michi's site:

KOGO



KGB



If I remember correctly, KGB's 50kW is pointed directly in to the Pacific Ocean. I can tell you that it is very difficult to hear this one at night in Phoenix.

As for KOGO, I have no idea when the upgrade took place. I wonder if the upward power shift occurred after the closing of the 600 kHz stations in Independence and Redding, CA; and the nighttime power limitations placed on KVNA, the 600 kHz station licensed to Flagstaff, AZ.

Nope. 760 has to protect KGU, Honolulu to the west and WJR, Detroit to the east. Those are the only three stations with any meaningful nighttime power on 760 in the U.S.

As a result, KFMB's night pattern is pointed directly north. They come in up here in the Sacramento area fairly strong and the signal goes much further than that. Fifty years ago, when the noise floor was much lower, I'd listen to them in Ukiah---560 air miles away. They came in like a local at night.

KOGO's power increase came with a move to the 760 site four years ago:

KOGO transmitter damaged?

Saturday afternoon, KOGO went off the air. The stream was OK. They returned about 7 pm but I noticed the signal strength had dropped. When I got to my office this morning, I turned on the radio and the signal is definately down-approaching the noise floor. Anybody notice this?

While I like your response, it does leave a question due to the recent changing of frequency of a license.



KEJY used to be on 790 kHz; now it's on 760 kHz and, if the link above is correct, is operating nondirectionally at night with almost 350 watts. Given the statements about KGB's signal, does KEJY's frequency switch put a curve in the San Diego station's night time coverage.

KEJY filed for the frequency move nine years ago, and the FCC granted the license to cover two years ago. If 760 in San Diego needed to make accommodations for that, it would have been done already.

If so, it still can't point west, because it has to protect KGU, Honolulu. My guess would be either no change or (and I'm not an engineer), more of a null to the northwest to avoid interference with KEJY.

@fybush would be the guy to speak knowledgably about this type of thing.

I heard KGB 760 4 times in alaska with a good enough signal to log it. I probably heard it a few times out side of that, knowing what I consider loggable.

I never hard KOGO good enough to log it, but im pretty sure i heard them a time or two well enough "to know it was them"

Here's some audio

That is an impressive piece of audio. Back when KFMB was a fairly groundbreaking AC (1973-1978), I would have put up with that signal in the car between Bishop and Reno.

The Best "San Diego area " signal was XEPRS.. before they lost a tower.
I can't find the audio I sent it for a reception report but heres another

XEPRS-AM 1090 Tijuana, BC, Mex Fri Dec 31, 2021 928pm AK Time.mp3

drive.google.com drive.google.com
And what I sent in for my report was even way better than that one.
It would pound in like this, nghtly.. all alone.. 2800 miles away or so.
Until it lost a tower then Seattle and it would mix.

Just to restate why 760 KGB (originally KFMB) is 5,000 watts by day and 50,000 watts at night. In the daytime, it once had to protect 740 KBRT, now licensed to Costa Mesa near LA but originally on Catalina Island off the California Coast. The FCC thought a 5,000 watt non-directional station in San Diego was far enough away from Catalina Island to exist 20 kHz away on the dial.

The good news for KFMB is that KBRT was originally a daytimer, since it had to protect 740 KCBS San Francisco, one of the oldest stations in broadcasting. So when KBRT went off the air at sunset, KFMB could let loose with 50,000 watts. But it has to protect the Class I-A station on 760 kHz, WJR Detroit, and Hawaii's oldest radio station, 760 KGU, which signed on in 1922. San Diego and Detroit are 2300 miles apart, so KFMB had to null its signal away from the Northeast. San Diego and Honolulu are 2600 miles apart, so again, KFMB's signal has to avoid going too far West.
