Touch professional version of the short-wave automatic sky tuning induction control

OGS-3 series FAQ question set

I have both 817 and 891 radio in hand. Can both of them be used?
817 or other radio with output power less than 5W, you can press the left arrow key for about one second to enter the system menu, enter the "Min PWR" menu, then press the left and right keys to change the value to 1-3, you can set it to QRP mode. After setting, press the long middle key for about one second to exit the system menu and return to the main interface.
891 or other high-power radio output greater than 10W can long press the left key for one second to enter the menu, set the tuning power value of 5-10, both for QRO high-power mode.

Second, the sky tuning standing wave can be tuned to below 1.5, why does it show low efficiency?
☞: Theoretically, the efficiency should be above 70% to have good transmitting efficiency. The default feeder is 50-7 lines, the total length of the feeder is 16 meters, if the feeder quality is poor or too long to cause unsatisfactory tuning results, you can press the long left button for one second to enter the menu, quickly short press the middle key, transfer to Loss ind, set to ON. Then quickly press the middle key once, the screen shows "losses xx", short press the left and right keys to change the feeder compensation, long press the middle key to exit.

Third, the screen will go off after a period of time, how to change to always display ?
☞: built-in battery version default ten seconds no RF signal input automatically off screen power saving, you can long press the left button for one second to enter the main menu. Short press the middle key to jump to "Serdel", short press the left and right keys to change the value, the digital value represents the seconds, the number 0 means turn off the screen automatically.

Fourth, the sky tuning has been tuned, but again it will be automatically tuned, keep this cycle, can not be used normally.
☞: This is the current antenna feed system has exceeded the technical indicators of the working capacity of the antenna itself, the antenna original standing wave is larger than 4, or the antenna original wave is lower than 1.5, the antenna itself has been self-resonant. Or for example, in 160m band, the current antenna transmitting oscillator is only 5m, or the current transmitting oscillator length is 40m, but want to adjust to 10m wave use. In this condition can only relax the tuning gate value. To change the factory default tuning standing wave value of 1.5 to larger. Long press the left button to enter the menu, short press the middle button to jump to "Min SWR xx", press the left and right button to set the value of 1.8-2.0.

V. What is the difference between the Pro version and the Standard version?
☞: In addition to the above functions, the Professional version can adjust all the internal parameters of Sky Tuner in factory mode.
1. calibrate the power, the antenna end of the series connected to the power meter and dummy load, in the main interface to the left to enter the bypass mode, the screen - symbol disappears, at this time, the sky tune will not be tuned, only display power and standing wave. Toggle to the left to enter the menu, then toggle down to enter the "POW CAL" menu, radio transmission, record the power meter indicates the power and the value of the power displayed by the antenna, toggle the left and right keys to enter the difference between the numbers, positive and negative digital values represent the difference in power power power. So that the sky tuning power display value and power table display consistent. 2.

2. standing wave effect. Antenna end of the string on the power standing wave table and dummy load, enter the "SWR CAL", radio transmission, record the power standing wave table to display the number, dial the left and right keys to adjust the input power standing wave table and the sky tuning display standing wave difference value, until the exact same.
