While this is a moot point I have wondered, in the 1970s why didn't many of the successful AM stations that had FM outlets matriculate their programming to FM, when FM was becoming popular.
For example, why didn't RKO move and continue the legacy of KHJ on 101.1?
In RKO's case, the issue was timing. In Fall 1973, KKDJ-FM made a real run, taking a rocket ship ride from #21 in fall 1972 to #12..but KHJ inched up to #1 from #2 the same book.
On December 1, 1973, KIQQ-FM (K-100) launched but simply split the available FM Top 40 audience..with KKDJ back to #21 and KIQQ tied for 24th.
KHJ slipped to #2 in the rankings but gained half a point over fall '73 (KABC, which had an unusually weak fall '73, came back big time).
KKDJ bailed out of Top 40 just before the fall '75 book to become KIIS-FM and go Adult Contemporary...which allowed KIQQ, with the FM Top 40 field to itself, to bounce into #13 (with roughly the same share KKDJ had two years earlier when it was the lone FM Top 40).
KHJ was still #2, but down almost a full point.
Fall '76 saw some growth in the FM Top 40 audience...KIQQ picked up half a point, while KHJ lost only a tenth and slipped to third, despite a strong showing from KRLA, which flipped back to (automated) Top 40.
Now this (late 1976/early 1977) is where RKO could have made their move. KRTH's oldies format was at a low point (having gone from 11th to 15th to 18th from fall '74 to fall '76).
Still, though...KHJ was #3, KIQQ was #12...there was more than 2 full share points between them. KRLA, on AM, vaulted past KIQQ in only about six months. And the risk of taking KHJ to FM was that history would repeat itself and all they'd do is split the available FM Top 40 audience, with both stations getting about a 1.6 and ranking in the high to mid 20s.
So RKO flipped KRTH to adult contemporary...and did very well. In Fall '77, KRTH zoomed to #10 with a 3.4 (KRLA abandoned Top 40 to fill the oldies void).
Trouble is that KRTH, being a well-programmed A/C, had a lot of appeal for older KHJ listeners. No doubt some time spent listening to KHJ shifted to KRTH.
Meantime, Top 40 had become a 4-way battle in the fall of 1977. KHJ slipped to #8 with a 3.5 (only a tenth ahead of KRTH), KFI's flip to Top 40 boosted it to #11 with a 3.1, KIQQ fell to 17th with a 2.4 and KTNQ (which debuted on December 26, 1976 with The Real Don Steele in afternoons) managed #18 with a 2.1.
Now, KRTH was too successful to mess with, and there was only a 2.4 in FM Top 40, which, even if KHJ could get it all, would be more than a full point lost.
In fall '78, with John Sebastian's AOR-flavored approach, KHJ fell out of the Top 10 and three-tenths of a point behind KRTH to #12, but still beat KFI, KTNQ and KIQQ.
By fall '79, KRTH was clearly the lead dog...almost a 4 share and #8 overall. KHJ had lost the lead in the Top 40 format....KFI was #10, KHJ was tied for 16th, and KIQQ was tied for 22nd (KTNQ had flipped to Spanish earlier that year).
And that...was that. KHJ went country in time for the Fall 1980 book. And by the time KRTH had another weak spell, where RKO might have considered resurrecting KHJ on FM, KWST (with former KHJ GM Tim Sullivan and jocks Bobby Ocean and Chuck Martin) and KIIS-FM (with former KHJ morning man Rick Dees) had already rushed in to fill the gap. And given that KIIS-FM just plain killed KWST (which sounded like latter-day KHJ on FM), there wasn't much reason to believe it would work at that late date.
Would KRTH have done as well in '77 and beyond if Charlie Tuna, Dr. John Leader, Bobby Ocean, Machine Gun Kelly, Don Cox and Shana had been playing the music? Probably. But at the time, it likely would have been seen as a disaster (KHJ had a 5.3 in fall '76...KRTH's "big" fall '77 number was a 3.4...nearly two points less). And, would an Adult Contemporary version of KHJ still be KHJ? Remember, it wasn't until 1982 that a true Top 40 on FM was a big ratings success in L.A.
Of course, the irony is that eventually, KRTH did end up with KHJ's format (the one from 1966)...ending another weak spell in 1992 by hiring Bill Drake to consult their refreshed oldies format with the Johnny Mann jingles, Robert W. Morgan in mornings, The Real Don Steele in afternoons and (briefly) Humble Harve in the evening.
