VHF AM Air Band Transceiver

MSA-2095 is a transceiver for land-board-land communications in the range of frequencies 108 ÷ 156 MHz in modality AM (avionic band).
MSA-2095 has been designed and realized using only electronic components in solid state and elaborated criterions of modularity.
Adopting a technology based on microprocessor, the use of the transceiver (user-friendly approach) becomes extremely simple and its control is furnished of a self-diagnosis system on its operating conditions (Built In Test Equipment - BITE).
