KJBS Radio, San Francisco
August 1, 1940
This QSL card
from Radio Station KJBS verifies a reception report sent in by an
unidentified listener. Collecting these verification post cards or similar
letters — known as a "QSL" in the hobby's parlance — were highly valued by listeners intent
on "hauling in" distant stations.
As noted on
the QSL card, KJBS operated on 1070 kilocycles (or 280.2
meters) with 500 watts at
this time, and broadcast during specified hours only — 10 p.m. until
local sunset on the following day — to protect the night-time signal of
50,000-watt WTAM/Cleveland, which shared the same frequency.
KJBS became today's KFAX, which broadcasts fulltime with
50,000 watts on 1100 kHz. from its transmitter plant in Hayward.
ORIGINAL SIZE: 4 inches x 6 inches.
