VHF Automatic Digital Direction Finders Announced By Simrad

Simrad, Inc. of Armonk, N.Y., has introduced a new generation of VHF automatic digital direction finders. Computer-controlled, these instruments utilize a unique microprocessor in place of motors of moving parts. Even when signal conditions are erratic, the Simrad/Taiyo Models TD-L1510 and TD-L1520 are said to lock on a radio bearing and hold it steady.

Both provide a direct bearing reading as well as a digital readout.

Direct bearings are indicated by 36 LEDs in 10-degree steps. Digital readouts are in onedegree increments. The digital display shows the bearing, the channel selected, and gives a reading of the signal strength on a level meter as a measure of distance.

Channels on the TD-L1510 include VHF, U.S. weather, and international fishing frequencies.

The TD-L1520 adds 121.5 mHz and the ability to scan eight channels. Both operate with Simrad /Taiyo's uniquely designed Adcock antenna for extremely accurate definition and sensitive performance. The units are a compact 5-5/16 inches high, 12 inches wide, and 11 inches deep.
