All engineers should be aware by now that the Federal Emergency Management Agency (FEMA) has scheduled the 2017 national EAS test for Wednesday, Sept. 27 at 11:20 p.m. PDT. This test will be originated and distributed via IPAWS only; the same manner as the 2016 National Test. The test will be sent with the event code NPT for National Periodic Test. All stations are expected to receive the NPT message from IPAWS or off-air and then to relay the NPT message on-air using their normal studio EAS equipment. The message will be sent with both English and Spanish language text and audio.

East County Magazine reporter Miriam Raftery says that an August 5th weekend thunderstorm caused KNSJ Descanso at 89.1 MHz to go off-the-air until repairs estimated at over $2,000 can be made.
The transmitter and antenna sit atop Monument Peak in the Laguna Mountains, giving the station a strong signal over San Diego and into Imperial County, “but the high elevation also leaves the transmitter vulnerable to extreme weather.”

KSVG, Mettler, CA, is licensed for 1.7 kW ERP (H&V) @ -309 M HAAT on 89.7 MHz with a highly directional Scala antenna. Their theoretical coverage pattern falls far short of reaching any part of Bakersfield. So, the licensee may have thought, “Why not just move the TX to Bakersfield and not tell anybody?” Check this out:
Enjoy your summer. See you in September!

In case you missed it, the FCC last week dismissed KFMB-AM San Diego’s FCC application to decrease its nighttime power to 10 kW.
KFMB-AM went from 5 kW to 50 kW nighttime power on 760 kHz in 1992 when state highway 52 was built between its towers and the station could leverage the Caltrans displacement funds to up its power. They tightened their peanut shaped antenna pattern with the third tower in order to continue to protect co-channel WJR Detroit. The lower daytime power is a rare case in the U.S. , but with KBRT Avalon short spaced at 740 kHz, KFMB wasn’t allowed to increase its daytime power past 5 kW. In most U.S. locations, stations either lower power at night or change to a directional pattern to protect the signals of stations that came before them.
