RADIO FREQUENCY

Figure 24

 - Radio Frequency tab

Select the Radio Frequency tab to set the operating frequency.  

The tab displays the radio type and TX and RX frequency. 

For convenience, the frequency is set by three drop-down lists containing valid channel
frequencies within the radio bandwidth.  The readout is in MHz.  You do not need a password
in order to set this parameter.  The frequency does not change until you write the data to the
unit using 

Link > Write Parameters

 from the menu bar.
