Frequency

Three controls and one indicator are used together to set and display the radio frequency on which your mobile radio will receive and transmit signals. In this connection, it is important to understand the frequency bands built into the unit and the way they are displayed on the Dual 7 Segment Display.

The 10 meter frequency range is broken down into four bands on your mobile radio. These are selected using the Band A / B / C / D knob.

Band

Frequency Range — MHz

A

28.000 – 28.495

 

 

 

B

28.500 – 28.995

 

 

 

C

29.000 – 29.495

 

 

 

D

29.500 – 29.700

 

 

 

Within each band, frequencies can be selected in 5 kHz increments, such as 28.005 MHz in Band A or 29.455 MHz in Band C. These are selected using the Frequency Selector knob after the band has been chosen.

- -4Dual 7 Segment Frequency Display

Frequencies are displayed on the Dual 7 Segment Frequency Display using a combination of numerical figures and decimal points. The figures indicate the first two values after the decimal point in the frequency, such as the 00 in 28.005 MHz. The right hand decimal point in the display indicates whether the third value after the decimal point in the frequency is

0 or 5 — if the right hand decimal is visible on the display, the third value is 5; if it is not visible, the third value is 0. The left hand decimal point in the display (between the two figures) indicates whether the two values before the decimal point in the frequency are

28 or 29 — if the left hand decimal is visible on the display, the first two values are 29; if it is not visible, the first two values are 28. Refer to the examples in the following table.

When this switch is in the off position, the operating frequency is increased or

 

decreased by 5 kHz with each click of the frequency selector knob. When it is in

increased or decreased by 10 kHz with each click of the frequency selector knob.
