Sigtronics SPCC-3 Communication Controllers
INTRODUCTION
The Sigtronics Portable Communications Controller
(SPCC) provides a pilot / observer "mission team"
with the ability to transmit and receive on multiple
transceivers simultaneously and talk to each other
via a voice activated (VOX) intercom. All these fea-
tures, plus its portability, make it ideal for the air-
borne or the ground mission team!
Typical Radio Configurations: Use with your air-
craft radios (permanently installed or hand-held
models) and two additional "FM" transceivers. A
typical "FM" radio transceiver would be: business
band, police, ham, CB, flight phone, hand-held air-
craft, marine, etc. (Some of these are actually AM
radios, however they can be used).
Dual Audio Panel (SPCC-3) capability allows each
headset position to select which radios to transmit

and receive on — independent of the other headset.
Each headset position has dual volume controls, one
for radio reception, and the other for their intercom
volume level.
Voice Activated Intercom feature allows "hands-
free" communication between headsets connected
to the SPCC. Start speaking and the intercom in-
stantly turns on to relay your message clearly to the
other headset. Stop talking and it turns off to reduce
background noise.
Portable design gives flexibility and eliminates ex-
pensive installation costs. Especially useful to small
departments that rent or lease. Or if a scheduled
aircraft is down, the SPCC can be used in an alter-
nate aircraft.
