Station Role

The RadioShack 22-510 regulated switching power supply functions as a highly reliable power source on the W8USR operating deck. Sourced out of station storage to fulfill active console service, it is dedicated exclusively to providing clean, regulated 13.8V DC voltage rails to run the AnyTone AT-D578UVIII Plus tri-band mobile radio under full transmit loads.

History with Radio W8USR

Originally kept in our equipment storage arrays as a flexible bench backup unit, the RadioShack 22-510 switching supply was brought back out to the desktop console to power our new tri-band digital mobile rig. It has functioned perfectly, maintaining stable rails and delivering dependable, noise-free current to support the station's expanded digital operations.
