Instruction Manual of TD-L1630 Chapter 3 3.1.4 Installation of Antenna Set the antenna on the flange welded at the selected position. Adjust its direction so that the connection between N and S element is set in parallel to the keel line. Confirm that BOW mark is on the bow direction. -
Page 24: Description Of Circuit
Instruction Manual of TD-L1630 Chapter 3 3.3 DESCRIPTION OF CIRCUIT 3.3.1 Antenna Circuit The antenna is a H type Adcock antenna, and a sense signal is synthesized with signals from NS and EW elements by special matching circuit. NS and EW signal are modulated by 135.6 Hz and the output signal is fed to the main unit through coaxial cable A. - Page 25 Instruction Manual of TD-L1630 Chapter 3 (3) PCA VCO-1 It has the 1 local oscillator with frequency synthesizer circuit, which generates 80 ~ 139 MHz. U3, U4 and U5 are the programmable counter for MHz setting. U2 is a phase detector and Q1, Q2 and Q3 are low pass filter circuits.

Page 30: Replacement And Re-Adjustment
Instruction Manual of TD-L1630 Chapter 3 3.4.3 Replacement and Re-adjustment (1) Re-adjustment of PCA IF/AF All IF amplifier circuits are tuned at their center frequencies to get the maximum gain. Therefore, shunt resistors for many coils shall not be changed. The following table gives standard level of the IF circuit. -
Page 31: Procedure Of Phase Adjustment
TD-L1630. To avoid this situation, make some 10 cm length of extension cables with connectors beforehand, and make an adjustment with following procedure to a good phase status by adding the extension cable for either vertical cable or loop cable. - Page 32 (4) Arrange a boat equipped with a VHF transmitter at 45 degrees against bow of the ship which installed the TD-L1630, and transmit VHF signal. (Refer to Fig.14) At that time, both ships shall cast an anchor to do not move.
- Page 33 (5) Change the length of extension cable so that the ratio of BM wave form between vertical and loop shall be in the ratio ranging between 1 (V) : 1 (L) and 3 (V) : 1 (L), when TD-L1630 receives transmitting radio wave from 45 degrees of heading.
