Radio facsimile receivers feature push-button station selection and nigh-contrast 12-inch recording.

Raytheon gives you a choice. The

RAYFAX 300 has 8 interchangeable push-button channels with a separate recorder. The RAYFAX 1200 offers 16 interchangeable push-button channels with a built-in recorder that operates unattended with automatic picture start-stop. Both units provide: • Onboard recording of World

Meteorological Organization weather charts, fishery charts, daily news for mariners, etc. • High-quality 12-inch wide reproduction on odorless, dust-free aluminized paper. • Long-life recording system with self- adjusting pens. • Advanced solid-state circuitry. • Simple operation.

The RAYFAX 300 Recorder is available separately for vessels equipped with a suitable wide-band receiver.

Fathometer" Recorder sounds to 1370 fathoms with 6 overlapping ranges.

RADIO FACSIMILE RECEIVER

Two Loran-C's with U.S.C.G. approved accuracy. One also a chronometer. One with options for steering, Lat/Long, and course /speed readouts.

Just turn a selector of the RAYNAV 3000 to "T". The upper readout becomes a chronometer accurate to 2 seconds a month... the lower readout a push-button stop-watch.

Our RAYNAV 6000 has optional plug-in boards for steering a computed course to a selected destination, and for direct

Lat/Long and course/speed readouts.

Both use mini-computers for optimum

Loran-C accuracy. Both offer: • Precise third-cycle matching. • Initial fixes accurate within 500 yards, repeated fixes within 50 feet. • Simultaneous tracking of multiple secondaries for verification of primary fixes. • Turn-on self-testing. • Continuous monitoring of

Loran-C signal quality and strength. • Manual cycle matching for extended groundwave and nighttime skywave coverage. • Provision for remote indicators, plotters, etc.

Designed for large, ocean-going vessels, the R-8220 sounds at 24 kHz with 600 watts of power... provides very precise recordings of underwater topography down to 1370 fathoms. Features include: • 6 over-lapping ranges of 0-110, 100-210, 200-310, 300-400, 0-720, and 650-1370 fathoms. • 7-inch calibrated recording paper. • Fool-proof magnetic keying. • Electronic fix marker. • Automatic time-varied gain to eliminate unwanted echoes near surface.

The R-8220 is completely self-contained except for hull-mounted transducer.

Fathometer" Digital Sounder goes to 500 feet or 240 fathoms with adjustable depth alarm.

A proven navigational sounder, the

DE-740 uses special signal processing to eliminate false bottom readings from schools of fish, thermal gradients, etc. • Large, easy-to-read LED display. • 1.5 to 500-foot and 0.2 to 240-fathom ranges. • 1% sounding accuracy. • Bottom alarm adjustable in 1-foot or 1-fathom increments down to 299 feet or 240 fathoms.

Designed for console or bulkhead mounting, the DE-740 is supplied with a remote equipment cabinet and a hull- mounted transducer.

Tough "specs" assure dependable operation in the harsh marine environment.

Raytheon products are designed and built to the toughest specifications in the industry. In onboard use and in the laboratory they have proven immune to voltage irregularities, temperature extremes in a corrosive salt vapor atmosphere, excessive shock and vibration. Maintenance, if required, is fast and easy. nut* j "t o o
