SEA long recognized as the leader in design and production of high quality
NMEA award winning MF/HF Single Side Band radios introduces the SEA 330. The
SEA 330 is an affordable 30MHz 300W (150W below 4MHz) SSB radio system
comprised of the 3301G Remote Transceiver Unit, 3300 Remote Controls (up to 4)
and SEA 1630 antenna tuner, operating @ 24 VDC. The American designed and
manufactured SEA 330 SSB radio is compliant to FCC and CEPT requirements.
Designed or extended transmit duty at high power levels, its innovative design
makes the 330 a high performance radio system that also incorporates maximum
features into minimum space.
The durable and attractive SEA 330 is pre-programmed with 1,000 stored
channels with capacity for up to 90 user-programmed frequencies. Built-in
features include telex compatibility; voice and telex scan modes, a built-in
distress alarm, Necode ScanStop accessibility, intercom capability between
multiple stations and self-diagnostic troubleshooting.
Utilizing the SEABUSS interconnection system, the SEA 330 has been designed
with ease of operation in mind. Intra-system communication, accessed via
simple control terminal keypad entry, allows all system components to talk
back and forth. The result is instant recall of data and frequency
information, with display annunciators clearly indicating radio status
throughout the process. To learn more about the advanced 330 radio or other
