Description/Nominal Signal Levels
Voltage Doubler Circuit. Nearly doubles the 14.2V supply. This output is then regulated to provide the 15V
steering line voltage for the receiver and exciter. Necessary for possible low input on the
14.2V line.
Flash Programming voltage regulator. A regulator that, when enabled by the software, provides 12V to allow
programming of the Flash device.
Analog 5V regulator. Provides the 5V supply, vcca, for the analog portion of the Station Control Board (see
Audio sheet).
