To follow up on Big 121's post:
The KOGO AM-FM simulcast was broken on Fri. 11/16/12 @ 7pm when the FM side went all-Christmas.
The ho-ho-hos (not the snacks, silly-though they're gone, too! ;D) ended on the FM on Wed. 12/26/12 @ 9:57am with 95~7 KissFM starting.
The December '12 PPM period was from Thu. 11/8-Wed. 12/5 and Holiday '12 was from Thu. 12/6-Wed. 1/2.
For December '12, the simulcast lasted 8 days 19 hours; they were split for 19 days 5 hours.
For Holiday '12, the FM was "Holiday" for 20 days 10 hours and "Rhythmic Oldies" for 7 days 14 hours.
Thus, the numbers seen on the Arbitron reports for the following months should be seen as follows:
Station Format Owner Aug 12 Sep 12 Oct 12 Nov 12 Dec 12 Hol 12
KOGO-FM R&B Oldies Clear Channel 2.8 2.8 3.0 3.7 1.7 3.6
KOGO-AM Talk Clear Channel -- -- -- -- 2.6 2.6
Aug 12 = AM-FM simulcast Talk = 2.8
Sep 12 = AM-FM simulcast Talk = 2.8
Oct 12 = AM-FM simulcast Talk = 3.0
Nov 12 = AM-FM simulcast Talk = 3.7 (Election coverage)
Dec 12 = partial simulcast (8+ days) - AM Talk (28 days) = 2.6
FM Talk (8+days)/Holiday (19+ days) = 1.7 (unsure if 1.7 applies to all 28 days)
Hol 12 = no simulcast/combining - AM Talk = 2.6;
FM Holiday (20+ days)/Rhythmic Oldies (7+ days) = 3.6
