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. Band A B C D Frequency Range -- MHz 28. 000 ­ 28. 495 28. 500 ­ 28. 995 29. 000 ­ 29. 495 29. 500 ­ 29. 700 Frequency Frequency Display Receive and transmit frequencies are shown directly by the 6 digit numeric display in 100 Hz increments. -- Frequencies are also displayed on the Dual 7 Segment 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. Frequency Display Frequency 28. 000 28. 005 29. 000 29. 005 28. 350 28. 455 29. 250 29. 635 28/29 MHz 0/5 kHz Channel Display Within each band, frequencies can be selected in 5 kHz or 10 kHz increments, such as 28. 005 MHz in Band A or 29. 455 MHz in Band C.

When the button is in the in position, faster tuning is available because the operating frequency is increased or decreased by 10 kHz with each click of the frequency selector knob. 12 English Nothing comes close to a Cobra® 13 Your Mobile Radio Indicators and Microphone · Your Mobile Radio Operating to Receive and Transmit · Indicators Analog Meter The meter needle swings proportionally to the strength of the incoming signal or RF output power in receive or transmit modes. When used to tune the antenna or monitor the quality of the coaxial cable and RF electrical connections, the needle swings proportionally to the ratio of standing wave voltage and RF output. If there is any degradation in these, due to humidity, salt, spray, vibration or corrosion, the SWR meter reading will rise, thereby indicating that a problem exists.
