I'm curious about a couple things Gabbert has been credited for in radio lore. Perhaps your status as the world's greatest living radio historian can confirm or deny:
1. That his KPEN was either the first, or one of the first FM stations to recognize the future potential of FM and go STEREO in the mid 50s.
2. That he was the first in the nation to market his station with other than call letters when he received the call letter change from KPEN to KIOI, and called the station K-101. The story has it that after granting the new calls, the FCC objected to the handle "K-101," but could not do anything as long as he abided by the required top of the hour legal station ID. Before that time, stations would sometimes make words out of their call letters, (for example: K-Bay, K-Jaz, and there was "Kadio Radio" -KDEO - in San Diego), but otherwise stuck with call letters. If true, this alone gives James a coveted place in radio history, since he would get credit for sending us down the path to the "Wolfs" and "MOViNs," that we're inundated with today.
Llew, first of all, I'm not even in the top 500 of radio historians, living, dead or somewhere in between.
I put together the text that appears on the front page of the Broadcast Legends website (
www.BroadcastLegends.com) about Gabbert which notes that KPEN was reputedly the first station west of the Mississippi to convert to multiplex stereo, which it did in 1961.
According to one website, Major Armstrong and John Bose developed the multiplex system in 1954, sets started to appear in 1961, and the standards for FM multiplex were approved in 1962, which, if anything, would qualify Gabbert at the very least as an early adopter.
A cursory glance through my notes shows that a few other San Francisco FM stations didn't go stereo until a bit later. For example, KAFE 98.1 (later KABL-FM, now KISQ) went in late 1962, as did KMPX 106.9 (now KFRC). KOIT 93.3 (now KRZZ; not the current KOIT) didn't go stereo until 1967.
As to call letters, I can't think of any station that used a straight dial position reference as K-101 did at that time. (It was also serendipitous that Gabbert bought KSAY/1010 here and made it KIQI -- K-101 AM; there are very few markets where such a thing would be possible.)
Someone here once posted that Gabbert got around the FCC requirement by having the "K-101" ID sent through the right stereo channel and the legal "KIOI" through the left channel simultaneously (or vice versa). I'm sure I've got a recording of it done that way somewhere in the archives...
