If you see odd TV and radio signals around El Centro, Calif., they may be coming from experimental licenses from the Naval Air Station.

Hatfield & Dawson, a Seattle-based engineering firm received the licenses WF2XAE and WD22XYJ "to model and transform psychological operation (PSYOP) equipment."

The WF2XAE license allows operation on TV channels 2, 4, 10, 15, 30, and 63, while the WD2XYJ license authorizes operations on 88.3, 89.1, 93.5, and 97.1 MHz in the FM broadcast band.

Another experimental license grant in the FCC list of experimental actions from 3/1/09 to 5/1/09 that might be of interest to readers is WE2XZK, issued to Qualcomm, Inc.

It authorizes operation on 698–710 MHz, 728–740 MHz, 746–757 MHz and 776–787 MHz for developmental testing and demonstration of new R&D technologies in San Diego, Calif.

Not all experimental work is in the VHF, UHF and microwave spectrum. Thales Communications received a new experimental license to operate in the 2 to 30 MHz band for "the test and development of HF technology" at a fixed location in Clarksburg, Md.

Vaisala was granted a license to use the AM broadcast band 560–1600 kHz and 1800–1900 kHz for testing and evaluating "electronic remote sensing system for measuring soil moisture" mobile in Tombstone, Ariz.
