But ... exactly
what date in 1941? I ask because on August 11, 1941, K45LA first went on the air at 44.5
mc and is today's KRTH at 101.1 Mhz ... KALW's own page on the subject says they were licensed in March but they say September 1 was the first day of "regular broadcasts". Having the license does not make you first if someone else got on the air before you finished constructing the facilities.
And
this article in
Broadcasting from January 20, 1941 indicates that K45LA had gotten their grant. No mention of any other CPs issued in California.
Call me skeptical, but ...
The CP for KALW was granted 8/14/1940 according to the station's FCC history cards;
Broadcasting magazine the following week had that date as 8/15/1940. That
Broadcasting page also answered another question that I had upthread. There were reserved channels for non-commercial, educational stations: five channels, 42.1 to 42.9 MHz. (footnote 1) KALW was granted 1,000 watts on 42.1 MHz.
The history cards state the following grant and/or application dates (grant dates unless otherwise noted):
2/27/1941 - amend CP for new transmitter
3/12/1941
application date - license to cover
3/27/1941 - extend CP to 5/14/1941
5/14/1941 - extend CP to 8/14/1941
9/18/1941 - license to cover
granted
Broadcasting had a list of FM station permits and statuses in its August 18, 1941 issue. There were 53 of them. For KALW, it listed: "KALW, Board of Education of the San Francisco Unified School District, 42.1 mc, 1,000 watts,
now on the air". (footnote 2)
In that same list, K45LA is indicates as having "special commercial authorization". I didn't dig further to see what that was about.
There's not much in the way of contemporary local attestation of KALW that I could find. It was situated within the SFUSD's Samuel Gompers Trade School, which offered numerous free classes for a variety of manual skills and may have been used later in 1941 for defense-related radio training. The trade school was at the center of controversy in 1941 after its principal had been demoted and a grand jury report questioned the effectiveness of the training programs at the school. Ironically considering its name, at least one union local also lodged protests against the school's offerings of machinists' training. I found a few Bay Area newspaper articles that indicated KALW had a chief engineer by July 1941, K. L. Dragoo, who was teaching defense-oriented radio classes in Palo Alto as well.
So where does that leave us? I've often said that it can be impossible to determine who was the "first" with something or another related to radio. That may be the case here.
Lacking contemporary attestation, I have to fall back on speculation: the district felt it was ready to go in March 1941 when it filed for the license to cover. It took the Commission six months to make the grant.
Broadcasting reported the station on the air in August, a month before the grant. The station may have been on the air from time to time while awaiting the final grant. When you look at FCC history cards for educational stations, they often requested SSAs to stay silent during vacation or summer periods. The SFUSD's Gompers trade school, however, appeared to running at full tilt in the summer of 1941 with defense-oriented classes. (footnote 3) KALW may have waited to inaugurate a regular schedule until it felt it was on firm legal ground with an actual license rather than a CP, but may have had periodic broadcasts for some reason or another. Without better contemporary accounts, that's the best I can do.
Related? K45LA was a Don Lee operation. A splashy
Los Angeles Times article from August 10, 1941 promoted that station's inaugural broadcast the next day. I think you can definitely say that FM had more of a presence and mindshare in Los Angeles than in San Francisco. As it turns out, Don Lee also had plans for Oakland. The
Oakland Post-Enquirer of April 30, 1941 had an article about those plans. Don Lee had obtained an option on 2½ acres of land at Marlborough Terrace and Grizzly Peak Boulevard in the Oakland hills. (footnote 4) The plans called for a 50,000 watt station costing $50,000 with a possible TV transmitter to go on the site later. It appears that there was no further action taken by Don Lee.
But: that site is in use today, by KPFA!
Footnotes:
(1) Except when quoting, I adopt the modern practice of saying MHz rather than megacycles. Technically, "megacycles" really should have been expressed as "megacycles per second" or "mc/s", and that's what saying "mega-Hertz" does.
(2) It's possible
Broadcasting got ahead of itself. It's hard to say.
(3) Keep in mind this was
before Pearl Harbor, but people were clearly seeing that there was going to be some kind of war.
(4) The article misidentified the location that Don Lee had optioned as Berkeley. Nope, it's Oakland. I used to do road biking right through that intersection.
