迎接“希望号”近日尝试接收ariss但抄收不到信号，请教各位如何能抄到信号？
今天16：00左右iss在北京上空飞过，这个几分钟里我试了以下频点都没有信号
dnlink: 145.800* nfm voice+packet+aprs
dnlink: 145.800* nfm repeater
dnlink: 145.825 nfm (testing)
dnlink: 143.625 nfm (vhf-1 voice)
dnlink: 143.635 nfm (old military voice)
dnlink: 130.167 nfm (vhf-2 voice)
dnlink: 247.000 am (evas)
dnlink: 463.000 tv-1
dnlink: 436.000 tv
dnlink: 400.100 esa global
在此请教有经验的朋友，如何能抄收到iss和其它卫星的信号，谢谢！
