Fresno / Central Valley KJOP Lemoore

R

RF101

RadioDiscussions archived some great dialog about AM radio in the Central Valley. Apparently there were several signals between Fresno and Bakersfield that no longer exist.

A Google Earth street view of the KJOP transmitter site really does suggest a true "radio shack".
The station runs just 250 watts daytime then jumps to 1000 watts nighttime. Is that low 250 watts because of the Bakersfield station on an adjacent graveyard channel? There are not too many graveyard stations still running just 250 watts. KJOP is one of them.
 
KLAM 1450 Corvdova, AK runs only 250 Watts.. thats all it needs....they joke.,. "We have trouble being heard 10 miles away but can be heard in finland". i hear them nightly 300 miles away.

Though, theyre not limited to 1kw.. KLAM, if it wanted could go to 5kw or 10kw.,

oh, so in Alaska the 'graveyard' channels are not restricted to 1kw? Can you give examples of 5 or 10kw on a graveyard channel? Is it the same in Hawaii?

1240 KEWE in HI is 5KW

No stations in Alaska have taken advantage of this rule
 
KCLU-AM 13~Forty operates with 740 watts, day and night. More than enough power for the eight people in that toney town who listen to Ancient Modulation. Probably can't get 1kw due to its proximity to el Pacifico.

How would that work? Other graveyards are right on the waters edge and get full 1kw. I would think it must be short-spaced with someone else, but maybe wasn't when the local channels were limited to 250w.

Could be short spaced...could be first/second channel adjacent issues. Back in the day, many of the graveyards ran 1kw day, and 250 watts at night. Later they were allowed to bump up to 1kw at night, provided they accepted interference from similar stations on the same frequency.

I remember the late 50s into '60,'61 when they were 250/250 then about 62 they got to bump the day power to 1kw. So.. I would think there must've been some short spacing problems then.
 
Here's a weird one for you:

KOBO 1450 Yuba City, CA, it's 160 watts daytime, and 500 watts at night. I have no idea why they run at such low power during the day?
 
KOBO filed this week to change power to 166 watts Day 820 watts Night ND-U

This application makes two minor “housekeeping” changes to the licensed daytime operation of KOBO. KOBO operates from one of the two towers of the KUBA antenna array. The coordinates on the current KOBO license are those of the center of the KUBA array, this application uses the coordinates of the southwest tower of the KUBA array, the tower used by KOBO. The current license lists the KOBO antenna height as 56.4 meters and 108.6 degrees, which are inconsistent. The KUBA license also lists the tower height as 56.4 meters, so this application uses that height, which is 98.2 degrees at 1450 kHz. The daytime power of KOBO
is increased from 160 to 166 watts to maintain, as closely as possible, the currently licensed daytime RMS.

Nighttime
KOBO is a class C station which was originally licensed as a 100 watt operation. Its power was increased to 500 watts as a result of the general power increase for class C (then class IV) stations. In 1989 we prepared an application, BP890424, requesting that the nighttime power be increased to 1 kW. That application was granted and the station licensed with those facilities.
