In the electromechanical antenna switching systems employed before solid state antenna switching systems were introduced, the blending was a by-product of the way the motorized switches worked.

The warhead section, just aft of the guidance section, contains the proximity fused warhead, safety-and-arming device, fuzing circuits and antennas, link antenna switching circuits, auxiliary electronics, inertial sensor assembly, and signal data converter.

Radiotelegraphers who aspire to the fluency of Morse code QSK operation must ensure that their radio equipment includes the hardware capability for radio frequency antenna switching that operates rapidly enough to allow listening between signals at the appropriate Morse code sending speeds with appropriate lifetimes and reliability.

Instead of using the telegraph key to directly control antenna switching, semi break-in radio transceiver equipment typically uses the telegraph key to control T / R switches indirectly, but still automatically, by passing the telegraph key information ( usually in the form of a keyed audio tone ) through a radio transceiver's " Voice-operated switch or VOX " circuitry.

Blueberry took WFAU off the air on July 1, 2013 to facilitate repairs to its antenna switching system; shortly afterward, the station was purchased for $ 16, 200 by Blue Jey Broadcasting, owned by Bob Bittner, who assumed control on September 27, 2013 and returned the station to the air on October 16 with an adult standards / oldies format similar to Bittner's other stations, WJTO in Bath and WJIB in Cambridge, Massachusetts.
