    SaveAT&W¯¯

    The above is that under the condition of 340K air rate, you can limit the frequency from 902.400 至 907.500. You can also choose to limit the frequency from 922.800 至 927.600. A channel of 400K is required. At least 51 從渠道 902.400 至 927.600 are required. If the air rate is 230K or below, Only one channel of 280K is needed, which can limit the frequency from 902.400 至 913.500, or the frequency from 916.700 至 927.600. If you need to cancel the restriction, 進入 000.000 at the beginning and end.
