[. . . ] When it is in the CAL position, the SWR function can be calibrated on the display meter by adjusting the SWR CAL control to move the needle to the calibration mark on the display meter face. -SWR CAL This control is used in conjunction with the S/RF / SWR / CAL switch to calibrate the standing wave ratio circuit to full scale on the display meter in preparation for measuring the standing wave ratio that the antenna is presenting to the transceiver. The standing wave ratio can be checked to insure that maximum power is being radiated for the longest signal range. The antenna must be in good condition, properly adjusted and matched to your transceiver. The SWR function of the display meter lets you easily measure your antenna condition. To operate this function, select a frequency near the middle of the range such as 28. 850 MHz or the one you plan to use most. With the power on, set the S/RF / SWR / CAL switch to the CAL position. Press and hold the microphone Press-To-Talk button and, using the SWR CAL knob, adjust the meter to the CAL position indicated on the display meter. Then, while releasing the microphone button, switch the S/RF / SWR / CAL switch to the SWR position. Again press and hold the microphone Press-To-Talk button and read the SWR indicated. Generally, readings up to 3 are acceptable, but a reading greater than 3 indicates that you are losing radiated power and antenna adjustment may be advisable. 10 English Nothing comes close to a Cobra® 11 Your Mobile Radio Frequency · Your Mobile Radio Frequency · 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. 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 Band A / B / C / D This control selects the desired frequency band. -Frequency Selector This detented control is a 360º multi-position switch used to increase or decrease the operating frequency in 5 or 10 kHz steps within the selected band. +10 kHz / Off 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 the +10 kHz position, faster tuning is available because the operating frequency is increased or decreased by 10 kHz with each click of the frequency selector knob. --- 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. -Dual 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.
