刚刚11:41-11:45bjt
iss通过南京上空145.825 抄收到3次packet的信号，信号59.
感觉好像是间隔2分钟一次。

是的，不错的信号。

iss的bbs也开始工作了

08:53-08:57 bjt 145.825收来自国际空间站的信号，信号59.
确认为每次packet的信号间隔为2分钟。
在仰角为3度的时候依然能清楚的抄收到信号。

下次经过南京的上空为10:25-10:34，几乎过顶。将覆盖中国大部分地区。

这一次过顶啥也没听到，关了？

bg6agb和我也是，刚才啥都没听到

空间站不是800下来吗?怎变了825?825是usb还是fm?

昨这一次，我在户外用c150和本身的橡胶天线听到一声。
从 http://www.issfanclub.com/ 网站上看，aprs digi仍开着有packet信号下来。

以下是空间站的频率和模式信息，是fm模式。
目前aprs digi模式开着，145.825每隔两分钟发送一次数据包信号。我们目前在用的2m设备几乎都能收到。
