Manufacturer: SEA Inc.  A unit of Datamarine International
Description:
The SEA 222 is a compact, all solid-state, 150-Watt PEP, HF SSB
transceiver for the marine and HF radio service.
The SEA 222 covers the 2 to 23 MHz frequency range with channel
restrictions which are determined only by the rules
regarding
the
appropriate radio service. That is, the SEA 222 is equipped with a
"mask" which limits the transmitter operation to legally assigned
channels for the desired service. The frequency "mask" contains ALL
normally assigned (ITU) Marine channels and has space available for any
additional channels which might be desired.
The SEA 222 is fully synthesized with 100 Hz resolution and the
channel frequencies are controlled by a precision crystal housed in a
temperature stabilized holder. The transceiver is designed to operate from a 13.6 Volt, negative ground power system and is controlled by a
front panel mounted 4x4 keypad. The control computer operating system makes use of an "operator friendly" controller program in conjunction with the eight character alphanumeric VF (vacuum fluorescent) display.
