RX (MHz)
TX (MHz)
Enter RX and TX frequency in MHz in the appropriate dialog box.
Note: The RF frequencies entered must match the corresponding RF frequency on the
GeminiG3 mobile radios.
Entries must fall within the Min and Max indicated on top of the page (erroneous entries
will be highlighted in red) and must be multiples of corresponding frequency step (6.25
KHz for 700/800 MHz frequency ranges or 5, 6.25, or 10 KHz for UHF frequency ranges).
CalAmp recommends (in North America) offsetting the TX column frequency by +30
MHz for 700 MHz frequency ranges, by -45 MHz for 800 MHz frequency ranges, or by +/-
5MHz for UHF frequency ranges.

E.g.:
Assuming:
Min Rx=851.000 000 MHz
Max Rx=869.000 000 MHz
Offset=-45.000 000 MHz
Min Rx=851.000 000 MHz
Max Rx=869.000 000 MHz
Offset=-45.000 000 MHz
If selection for a channel's RX was:
Rx (MHz)=853.037 500
then its corresponding TX would be computed as:
Tx (MHz)=853.037 500+(-45.000 000)=808.037 500
Note: Exercise caution when entering RF frequencies. Paragon4 base station will reject
any entry with a wrong frequency step and will transmit at the previous correct entry or
return to its default (factory-configured) RF frequency setting.
