in ultralight communication systems, this two-channel intercom has been
specifically designed for two-place aircraft use. It integrates directly
with the ULTRA-COM system to provide air-to-air and air-to-ground
Our proprietary circuit combines four separate IC chips to
produce loud, clear, distortion-free transmission at any volume setting.
The intercom has separate volume controls which may be adjusted by either
pilot or passenger to meet individual hearing levels. The system also
includes a unique side-tone circuit that allows the user to hear his own
voice to assure proper operation. No other ultralight intercom has this
This system can be used as an intercom only or a complete
communication package with the addition of a transceiver of the users
choice and a matching interface cable with a push-to-talk switch.
(Interface cables are available for most popular transceivers).
The output of the intercom is .3 watts and the audio
pressure to the speakers is 116 dB. It is powered by a 9-volt alkaline
transistor battery which can provide up to 20 hours of operation. The
standard transistor battery was chosen because of its long life,
availability, light-weight and its gradual power reduction which provides
adequate warning of impending power failure. In a matter of minutes, the
battery can be changed, and you will be flying again.
An optional voltage
regulator can be installed which will allow the use of a 12-volt power
source to eliminate changing batteries.
