SMR Introduces Inexpensive SSB Radio —Literature Available Southern Marine Research, Inc.

NEW PHILADELPHIA DIVISION 30 Write 307 on Reader Service Card The Sea Lab 6511, retailing at $649.95, allows the coastal boater the capabilities of constantly be- ing in communication with the rest of the world. The SMR radio is said to be the least expensive SSB available today. Although the Sea Lab 6511 is priced as low as a quality VHF, there have been no sacrifices in quality or design features. Solid state construction insures years of trouble-free operation and a high degree of reliability, the manufacturer states. An out- put of 65 watts provides commu- nications capabilities over several hundred miles. Three factory- installed crystals (2182 kHz, the international distress frequency, 2638 and 2738, both ship-to-ship channels) are standard in the new SMR radio. The Sea Lab 6511 has the capacity for a total of 11 sim- plex or semi-duplex channels. Backlighting of a plastic panel indicates the channel being used. An indicator light also shows transmission is being made. A tuning clarifier allows the oper- ator to fine-tune the radio for sharp and clear reception. An- other unique design feature of the Sea Lab 6511 is the lack of an antennae coupler. This sim- plifies installation and reduces its cost. The SMR single sideband may be console-mounted or installed overhead. A specially designed snap-off bracket allows the radio to be readily removed. Other fea- tures include an external speaker jack and a front-mounted micro- phone. The Sea Lab 6511 features rugged construction for either commercial or recreational appli- cations. The SMR radio is a com- pact unit that weighs only 13 pounds.

Vessels built with CDS are re- stricted from operating in domes- tic service. Generally, they must operate in foreign commerce. However, the U.S. Supreme Court ruled last February that such ships could be used in domestic service if the CDS was repaid. Seatrain previously repaid $27.2 million in subsidies on another tanker, the Stuyvesant, which is now operating in the Alaskan oil trade. The Stuyvesant was the ship involved in the test case decided by the nation's highest court. Maritime Reporter/Engineering News
