       似乎用淘汰的CATV的LNB可以收ku段信号LNB可以将ku段信号频率降至SDR可接收的范围，理论上可以接收🛰️数据🤔网上各种教程都是针对NOAA的，其他的似乎少不知道himawari的信号如何（加密的话就真没办法了

       @bi119aTe5hXk 似乎经过变频之后的频率也在1G以上…

       @bi119aTe5hXk @siyanmao 有没有可能自己搭超外差接收电路（振荡和混频相对不难，SAW可能不太好挑（

       @Soybean @bi119aTe5hXk 都 SDR 了，用软件硬算应该可行吧…

       @siyanmao @bi119aTe5hXk 不对R820T严格意义上是个Tuner反正不支持气象雷达那么高频就是了

       @Soybean @bi119aTe5hXk RTLSDR啊… 那确实不太行。能不能把DVB-S的tuner给挪过去…

       @siyanmao @bi119aTe5hXk 那baseband芯片得支持吧，记得R820T2算是RTL2830U能支持的最好的了不用RTL2830U就得$$$

       @neoatlantis @bi119aTe5hXk @siyanmao RTLSDR应该支持10M左右的中频（和模拟FM收音机差不多），带宽是足够的，但是不知道怎么去控制别的tuner，那个i2c是否够用
