San Antonio's first FM station KYFM (owned by the Express
Publishing Company) went on the air November 1, 1946.
The transmitter site was located south of what would become US81
and just west of Coliseum Road. The transmitting antenna was mounted on a
self supporting tower at that location. The KYFM Studios were located on the
fifth floor of the Express Building.
San Antonio FM Radio Stations listed in White's Radio Log
(Volume 24 Number 2) for Spring 1947 (April, May, June) are:
In 1948 Radiocraft Magazine reported there were four
FM stations on the air in San Antonio:
Note the KISS and WOAI-FM frequency changes.
KYFM is not listed in White's Radio Log after 1950.
Nothing definitive has been found to indicate what happened to
KYFM. What is known is that The Express Publishing Company bought
KGBS-AM and changed the call letters to KENS during that time frame.
When US81 became IH35 and was widened to 6 lines, from looking at
older maps, the former KYFM tower site is now covered with asphalt.
According to the 2020 FCC Database 102.5 is no longer in use in
the San Antonio area. 101.5 is used for Low Power FM (LPFM). KROM are now the
call letters for 92.9. What is interesting is that KISS are still the call
letters for 99.5
just like it was in 1948.

located near the KONO Transmitting Towers on the right-hand side of the above map?

More Editors Notes: According to Herb Carl (and verified by
Bill Kiley) because there were so few
FM radios in the late 40s and early 50s KONO-FM was just a similcast of KONO-AM.
Additionally KONO-FM had a very small coverage area because the transmitting
antenna was located on a pole on top of the KONO Building on Arden
Grove. The KONO-FM antenna was relocated much higher for much better coveraage
once the channel 12 tower was built behind the KONO Building. Additionally
at that time the call letters were changed to KITY.
