The Sonar 2307 is a five channel 2 meter hand-held transceiver with a minimum 1.6W output. Weighing only 1 1/2 pounds without the snap-in rechargeable battery option, the unit can run for 8 to 14 hours on a battery charge. Standby current drain is only 10 mA.
The 2307 also has FCC type acceptance for use in non-amateur services.
Circuitry includes ceramic and crystal band-pass filters and transmitter protection against antenna mismatch. The unit uses all electronic switching (no relays) and military grade components and PC boards throughout.
There are connections for optional external antenna, earphone and battery charger.
