Transmitter RF power output
(a) Set the power supply for 12.5 VDC and con-
nect to "POWER" connector in the front
panel of the RT-841/PRC-77 with Test Cable
No. 2.
(b) Connect the test equipment in accordance
(c) Energize all test equipment. On the RT-841/
PRC-77, set function switch to the "ON" posi-
tion, and the frequency to 30.05 MHz.
