Much like KFRC, I think the great KMPC and KNX were crushing KHJ in the ratings.
Probably true, Llew. I can't find hard numbers to back it up (Billboard didn't start publishing full ratings data until the 70s...and Claude Hall didn't start excerpting them in comments in Vox Jox until the late 60s), but the Fall, 1966 Pulse ratings (the earliest I can find) give a clue:
1. KHJ (top 40) 9.0
1. KMPC (mor) 9.0
1. KLAC (talk) 9.0
4. KFI (mor) 7.0
4. KPOL (beautiful) 7.0
4. KRLA (top 40) 7.0
7. KABC (talk) 4.0
7. KFAC (classical) 4.0
7. KFWB (top 40) 4.0
7. KNX (mor) 4.0
7. XETRA (news) 4.0
12. KGFJ (r&b) 3.0
12. KWIZ (all request) 3.0
12. KWKW (Spanish) 3.0
15. KFOX (country) 2.0
15. KGBS (country) 2.0
15. KGIL (mor) 2.0
18. KALI (Spanish) 1.0
18. KBBI-FM (beautiful) 1.0
18. KBIG-AM (beautiful) 1.0
18. KBLA (top 40) 1.0
18. KBMS (beautiful) 1.0
18. KGER (religious) 1.0
18. KHJ-FM (top 40-simulcast) 1.0
18. KUTE-FM (beautiful) 1.0
18. KWIZ-FM (beautiful) 1.0
18. KWOW (country) 1.0
There are two things we know that happened here between early 1965 and this survey: The launch of Boss Radio and Bob Crane's departure from KNX. It's reasonable to assume that KMPC, KRLA and KNX were close to each other or tied at the top, with KFWB maybe a point or two back. Disaster in those days would be placing 10th or worse, since after that, it was pretty much lower-powered stations. That could mean as much as a five point difference in the ratings between KMPC and KHJ or KNX and KHJ. KLAC and KABC probably picked up some numbers from the old KHJ, which was heavy on talk and information. Ballpark guess for fall '64:
1. KRLA
2. KMPC
3. KNX
4. KFI
5. KFWB
6. KPOL
7. KLAC
8. KFAC
9. KABC
10.KHJ
11.XETRA
And some of those might be tied with others. Back then, the numbers were whole numbers, no decimal points, so ties were common.
