2.3.4 Offset Frequency Set (continued)
(1)
Set jumper J27 on the memory set board to Rx position.
(2) Key PTT and set the transmitted frequency (without modulation) by rotating C16* to the
desired Tx frequency. *(Revised from C37 in Rev. B document).
(3) Set jumper J27 to Tx position. Key PTT and without modulation set the transmitted
frequency by rotating trim capacitor, C37 to the desired Rx frequency.
(4) Set jumper J27 to the Rx position, key the PTT and without modulation, verify that the
transmitted frequency is the desired Tx frequency. If not, repeat steps 2, 3 and 4.
For the Tx frequency to be lower than the Rx frequency proceed as follows:
Set jumper J27 to the Rx position. Key the PTT and without modulation set the transmitted
frequency, rotating trim capacitor C16 to the desired Rx frequency. Release PTT.
Set Jumper J27 to the Tx position. Key the PTT and without modulation set the transmitted
frequency by rotating trim capacitor C37 to the desired transmit frequency. Release PTT.
Set jumper J27 to the Rx position. Key the PTT and without modulation, verify that the
transmitted frequency is the desired receive frequency. If not repeat steps 1, 2, and 3. If it is,
release the PTT and set jumper J15 to the Tx position, thus completing the frequency tuning.
