    八重洲 YAESU vx-6r 手台 硬扩频方法

     
    昨天入手一台八重洲 YAESU VX-6R,准备工作时和工人的VERTEX VX-168对讲,闲暇旅游玩机。到手看到能发射的频段为:137MHz-173.9875MHz和420MHz-469.9875MHz两个,看了下面的扩频文章,心痒。顾不得新机,扩了再说,不犯法也心理安慰!
    具体步骤如下:
             不需要开机壳,不要拆下VX-6R后背的6棵螺丝(电池下面有4颗),只需卸下电池,撕下装气压模块的那片塑料片。
        在机器的前部分中部靠下的位置有两排焊点(solder pads),一共13个,左边8个,右边5个。可以看到左边那排焊点2和4是短路状态,把4焊开,2保留不动。修改即告成功。
        再将塑料片按原样粘好(自带胶的)。
        装好电池,正常开机即可全频发射。
        把电池安装好,按住MODE、SET和DWMT这3个键开机,看到屏幕提示按F键复位CPU后再按一下F键。机器重新复位。这时候你会发现在40Mhz到579.950Mhz的段上都可以发射了。
             注意点:扩频后不要在 (88-109MHZ)和(480–550MHZ)段发射,以上频段不可以发射,否则会出现电池保护不开机问题,开关机也没用,只有把电池取下再放上去方可正常。
    扩频后各频段发射实测:
    1-广播波段:                     0.504-1.791MHz       无法发射,显示错误
    2-短波波段:                        1.8-29.995MHz       无法发射,显示错误
    3-50MHz业余波段:         30-87.995MHz        部分无法发射,其中30-75.995MHz可发射,76-87.995MHz死机
    4-调频广播波段:              88-107.995MHz       无法发射,死机
    5-航空波段:                    108-136.975MHz       可以发射
    6-144MHz业余波段:137-173.9875MHz       可以发射
    7-VHF和电视波段:    174-221.9875MHz       可以发射
    8-220MHz业余波段:222-419.9875MHz        可以发射
    9-430MHz业余波段:420-469.9875MHz        可以发射
    A-VHF和电视波段:   470-802.9875MHz        部分可以发射,其中470-488.9875可发射,489-579.9875MHZ死机
                                                                                                                                       580-802.9875显示错误
    B-警用波段:                   803-998.9875MHz      无法发射,显示错误
    死机后将电源充电器插上交流电,插拔一次电源插孔恢复。
