新腿9001机求教!
1:驻波情况与发射功率有关吗?当我用小功率发射调校swr cal时,只能看到三角符号出现在1 1.5 2 3一列数字的右下方(也就是3的右下方)旋转swr cal却不能使状态条到达小三角处,当我调大功率发射时状态条往右移了一点,但还是没有到达小三角处,再调大功率,又入往右移,最后功率调到一定程度时,可以看到状态条到达小三角处,再加大功率,状态条会超过小三角处,此时回旋swr cal可以使状态条回到小三角处,这正常吗?
2:当我用上述方法校准驻波比后,在29.6上发射,状态条到达2的右边,(几秒钟,不会烧机吧??)是不是证明我的天线需要调整?当我用较小功率发射时为什么没有驻波比显示?我在26m上用同种方法试验(偷偷的,不要告诉无委)发现驻波比会到达1.5右边,正常吗?
3:我在26m到30m之间一直用最小的步进进行手动找台,为什么没有找到一个台,只是在am方式下在27m到27.4附近听到很多老外在说话,有男的,有女的,还有一个男的在唱歌,(我肯定不是广播节目)是不是外国的电台信号呀?不是不能在台上唱歌吗?
4:我的电源有17伏之高,会不会烧电台?(自制的,没用稳压管,不知一般的7815能不能在大功率下稳压??)
5:怎样知道自已的机器有没有烧坏??
我用不锈钢试做的天线如下图:

1、正常,swr cal和功率要一起调,你可以先将swr打到最大,调功率使cal到小三角处,这时转到swr测量,就是这种状态下的驻波比了。我注意到9001在不同的功率下swr有一定的差别,一般是功率越大驻波比越高。
2、驻波比到2算是勉强,一般来说也不会烧机器,但最好能调到1.5以下。较小功率发射时没有驻波比显示是因为驻波比本身有一个灵敏度的问题。同一根天线在不同的频率驻波比是不一样的。
3、搜索业余电台应在业余频率上寻找,比如fm29.6、usb28.3,象你这样大海捞针~~~~~~~~~~~~~~~。27m是民用频段,有些人也并不是这么守纪律,比如说不能闯红灯的,但不少还是要闯。
4、电压17v太高了,建议你还是做个电源,稳压之后的电压不应高出15v。7815不够电流,可以考虑用几个并起来,但最好还是用大电流的调整管,电流在10a左右。
5、简单的判断,有发射功率应该就没烧。
6、天线最好还是做个地网天线,相关资料请用论坛查询。
