'DAYTIMERS' (incl. WJTO-730) GET NEW EXTENDED NIGHTTIME POWERS

J

JIBGUY

The FCC has just released new pre-sunrise powers and new post-sunset powers for all lowly AM daytimers! - For some stations, its an improvement, and for others it's worse.

WJIB-740 (Cambridge MA) now get 40 watts for pre-sunrise (previously 5 watts at pre-sunrise); and for post sunset, WJIB-740 gets to stay on with full 250 watts until two hours after sunset; which in summer is 10:30 PM.

WJTO-730 in Bath, MAINE gets a reduction of pre-sunrise power from 84 watts to an average of 15 watts, BUT gets to stay on 2 hours past sunset with 500 watts! ('daytime' power is 1,000 watts).
 
Is this just for stations on Canadian clears (like 730 & 740)? Or is it a wholesale extension to all-or-most AMs with daytime designation--including "regional" channels (or whatever they're called now)?
 
The new PSSA & PSRA authority is for all AM-daytimers, no matter what channel they're on. But its not for any full-time AM stations. A daytimer is defined as one who has overnight power of 249 watts or less. - "Most Daytimers" have PSRA & PSSA authority (pre sunrise and post-sunset authority), but 24-hour stations with 249w or less at night, don't. Therefore those 24-hour stations are not affected by this. What some of them DO have is "Critical hours" power levels, which in a way is similar in theory to daytimers PSSA and PSRA, in the fact that suchis an intermedia power-level between full daytime power and lower nighttime power level.
 
Bob, can you point me to anywhere this might be explained on the FCC website or something?

One of our readers reported that a local daytimer has been on later as of late, and this would explain it.
