2.5.5 140 MHz End Center Frequency Changes
The 140 MHz end (whether the Input or Output) can have the center frequency adjusted from 110 to 170 MHz.
Note that when the 140 MHz end is the Input, you must be sure that the input bandwidth can properly
pass through the 36 MHz bandwidth filter used in the translation. When the 140 MHz side is the Output it
will cause the 36 MHz bandwidth signal from the 95 MHz input to be centered at the output center frequency
that is selected.
At any time during the modification process, if you have made a mistake and do not wish to save the changes
you have made, do not press the MENU/EXECUTE switch; simply do nothing for approximately 30 seconds,
and the system will return to the normal operating mode or scroll to “R” and push the MENU/EXECUTE
switch and select “NO” in the “SAVE SETTINGS?” window. To change the Frequency Translation:
