Page 5: Theory Of Operation
TR-50 Theory of Operation Theory of Operation I. Power Control The control board draws a general 13.8V dc power supply, which is converted through U1, a 3-terminal regulator, to 8.0V dc for the receiver and transmitter. Fig. 1 Power Supply Block Diagram II. - Page 6 TR-50 Theory of Operation V. AF Amplification The receive audio is routed to another AF amplifier NJM386M, which is convenient for the users to monitor the activities of current channel. VI. Definition for control ports The definition of all the pins goes as follows: 1 .
