[BC] CALLING ALL AM DAYTIMERS

[PeterH5322]

One example of less than 250 watts, but greater than that RMS which would 
be provided if 250 watts was employed, is KPIG, Piedmont, CA, which 
really was a move: 1) from the North Bay (San Rafael, a few counties 
away, as the car drives) to Oakland, and 2) from Oakland to Piedmont.

The night operation, which is indeed Class B, provides a "first service" 
to Piedmont, the new COL, but still provides service to Oakland and to 
San Francisco, to the extent it is limited by KGA.

(This station is on 1510, but it must protect stations on 1480, 1490, 
1500, 1510, 1520, 1530 and 1540 ... luckily, for it, the stations on 1480 
and 1540 have been deleted.

(It certainly helped that KGA radically changed its operation, diplexing 
with a co-owned station much lower in the band, and in this process 
changing from DA-N using customary radiators to DA-2, using an atrocious 
(for a Class A) 225 degree radiator as part of its array).

Anyway, KPIG has a nighttime RMS of 142.86 from its four tower array (one 
"tower" was added to its rooftop day array, this "tower" being a vertical 
wire suspended from a horizontal wire strung between two real towers).

As the minimum RMS for a Class B is 140.82, this station meets the 
requirements for Class B (a specious claim of "first service" surely 
helped, too), and it is so licensed.

Yet another "conversion" of a half-assed station in a major market by 
Saul Levine.
