speed data transmissions.

The first is a radio/telex station that handles FEC or SITOR mes- sages in the ARQ mode; several of these stations have been installed and are in operation.

The second is a computer radio network station which permits com- puter-to-computer transmissions over Hull's HF/SSB radio link- said to be ideal for business commu- nications between boat and shore.

Either station's transmit power may be boosted by using Hull's soon-to- be-released 1 kw linear amplifier.

M500D meets all communications needs. Specially constructed with extensive moisture protection sys- tem, the IC-M500D is water-resis- tant, providing high reliability in moisture and saltwater air environ- ments.

The IC-M500D features: exten- sive new water-tight design; excel- lent receiver sensitivity and per- formance; six scanning systems in- cluding dual watch and tri-watch; 48 memory channels in three 16-chan- nel banks; 5-watt audio output, 10 watts with optional external speak- er; 30-watt two-way hailer/intercom system; manual 30-watt foghorn (300Hz tone); optional plug-in scrambler; full duplex system stan- dard on IC-M500D; all U.S. and international channels, plus expan- sion channels; and waterproof mi- crophone/waterproof gold-plated connectors.

The IC-M500D also receives po- lice, fire and land mobile frequen- cies. Additionally, the FCC-type ac- cepted IC-M500 is backed by a one- year warrantly and lifetime service policy.

The latest products from Kelvin

Hughes, Ltd. of England, a subsid- iary of Smiths Industries, pic, are the new generation Concept radar systems, HR 2000 and HR 3000.

Concept radar systems from Kel- vin Hughes provide a unique and flexible approach to ergonomic bridge layout. The Concept HR se- ries has been developed to achieve total radar system integration in either existing vessels or bridge de- signs for the 1990s.

The high resolution monitor, key- board and processor of the Concept

HR radar can be situated remotely in any configuration—either bulk- head, deck console, deck head or desk-mounted, or can form one fully integrated unit in which the moni- tor angles can be adjusted to suit operator preference. Additional re- mote monochrome or color monitors can also be included in the Concept package.

Concept HR systems offer rela- tive motion, true motion, and ARPA facilities, combined with E-Plot II, an enhanced version of the unique

Kelvin Hughes electronic plotting program. Identical positioning of keyboard controls for these features throughout the range assists opera- tional confidence and familiarity.

On the Concept HR system, all ship data and status can be ideally zoned for instant assimilation.
