Main Reference Frequency Adjustment
Setup the test equipment as shown below.
Set the channel to CH16.
Use the [H/L] key to set the transceiver to “LOW” power.
With the PTT switch pressed, adjust TC1001 so that the Frequency Counter
reading is 156.800 MHz ±100 Hz.
Transmit Power Adjustment
Setup the test equipment as shown below.
Set the channel to CH16.
Use the [H/L] key to set the transceiver to “HI” power.
With the PTT switch pressed, adjust VR1001 so that RF output power is 24 W ±0.3
W.
Release the PTT switch, then set the transceiver to “LOW” power by the [H/L] key.
