Las Vegas KLAV-AM files to change to 1240 and relocate their transmitter

F

Frequency1

This Engineering Report has been prepared in support of an application by Lotus Broadcasting
Corp. to relocate the antenna of KLAV(AM) 1230 kHz, Las Vegas, Nevada, and change the
frequency to 1240 kHz. Lotus proposes combined operation with KRLV(AM) 920 kHz and
KENO(AM) 1460 kHz from the transmitter site currently used by KRLV and KENO. Lotus also
has a pending application to relocate KWWN 1100 kHz to the KRLV/KENO site1, resulting in a
total of four stations operating from this site.

The ghost of Alan Roycroft have migrated to Nevada.

(Roycroft was the well known Hawaian and South Pacific engineer who did, I think, all the three and four station combinations in Honolulu where nearly nobody, not even KGMB could afford or find the land for a single station use.)
 
Two filings at a time, and nothing more.
Color me skeptical, but I don't think KKGK is going to make it. There are many other options to feed that translator. It just would not be worth the expense and complexity on top of already sizable project. This is a money/land move, and nothing else. I hope they have the bodies and brains to get it done on schedule and within budget. I hope the Kalmensons can follow through on this project, and not drop the ball like Audacy did.
 
ENGINEERING REPORT APPLICATION for CONSTRUCTION PERMIT to RELOCATE ANTENNA has been filed.

In fact would it be simpler just to do the 940 24 / 7? One less thing to worry about. 50 watts isn't going to make much difference coverage wise and it's AM most likely nobody will notice.

1000 watts maximum, but if an AM station relocates, it often has to dial power down slightly if it's going to a more efficient antenna system or moving somewhere that would create new prohibited overlap with other stations.

IIRC The old class 4s all went to 250 watts at night unless grandfathered lower power or the antenna efficiency was too good for 250 watts. But then the FCC "turned up the interference" an let everyone run daytime power 24 hours a day. I thought everyone ran daytime power 24 / 7. I didn't know there was "nighttime" protection. There are literally 100's of stations running close to 1 KW the class C channels can be "loudest" at night.

In the 1940's thur 1990 a lot of folks in cities with populations under 100,000 made a lot of money with these stations. Just enough nighttime signal for local highschool sports, reasonable power bill, no directional headaches and depending on the distance from a airport no tower lighting.
 
You are correct about there being no interference considerations from one class IV domestic signal to another at night, and if you read the KKGK engineering report, it doesn't address any other signals on 1340.

What it does address, however, is co-channel interference to Mexico on 1340 and adjacent-channel interference to 1330 and 1350 in Mexico and the US. It looks like the issue with KKGK remaining at 1000 watts off a more efficient antenna is that it would put just enough additional skywave toward the 1340 in Mexicali to push it over the 50% RSS limit. Dialing back to 940 watts at night keeps it at 49.7% and avoids the need for Mexican coordination to accept additional interference. (And in the real world, the difference between 940 and 1000 watts in the soup of Vegas electrical noise at night will be imperceptible, of course.)
 
I forget how close to Mexico they are. If it was my station I would file for 940 watts 24 hours. Keep it simple. No clock to worry about. Like you said 50 watts is not going to make a difference.

In my town (Hermosillo), an installation with a combiner or RF Multiplexer for 4 AM frequencies was operating for more than 10 years. Well, it's Mexico, you can't expect more with the regulators, at least today the regulations are much stricter. But the stations were from 1Kw to 10Kw, it was terrible how the installation behaved.
650 khz - 1kw
950 khz - 10kw
1110 khz - 1kw
1250 khz - 5kw

That was the first time I tried snake. Actually rather tasty if done with tomato, red and green peppers and Cholula sauce.

(I can not say I was as pleased with garrobo in El Salvador)
 
Have you ever tried alligator gumbo. It is a wonderful dish if prepared correctly. There is something to be said about eating something that can eat you.

Let me guess... this is off subject.

Anyway, never tried alligator. But that reminds me of one of the early 007 movies where a bad guy was in a swamp compound with gators and there was a sign saying, "TRESPASSORS WILL BE EATEN".
