KJBS QSL Verification Card, 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.
