Apelco Announces New Marine Radiotelephone

A new high-performance VHF/ FM synthesized marine radiotelephone with capability for 56 transmitting and 99 receiving frequencies is now available from Apelco Marine Electronics, Manchester, N.H.

The 25-watt AF-40MA covers the entire VHF worldwide marine band, with no need for adding or changing channel crystals. Its precisely calibrated synthesized design ensures "pinpoint" tuning on all domestic and international marine frequencies.

A two-channel scanning circuit enables the AF-40MA to automatically monitor the distress and calling frequency (Channel 16), and a second channel of the operator's choice. Indicator lights —red for Channel 16 and green for the selected channel—signal the presence of radio traffic for quick-glance recognition by the operator. A quick-select Channel 16 switch enables instant use of the emergency channel.

Other design improvements include circuits to reject interference from busy in-harbor radio services of TV, taxi, police and fire; and modular plug-in cir- cuitry for servicing ease.

The AF-40MA also offers such standard features as an adjustable quick-release mounting yoke for bulkhead, overhead or counter- top installations; a radio frequency indicator light to show when RF power is being transmitted to the antenna; large readable controls on a dimmable back-lit panel; component protection from reverse polarity and antenna open and short circuits, and a selectable one-watt output mode for harbor use. The AF- 40MA meets all applicable FCC regulations, including party boat requirements for low-voltage operation.

Additional i n f o r m a t i o n and specifications are available from John Millard, Apelco Marine Electronics, 676 Island Pond Road, Manchester, N.H. 03103.
