4.1 向 APRS-IS 直接推送消息

1. 连接服务器

$ nc 66.109.111.25 14580
# aprsc 2.0.0-gf5e3f21

2. 登陆

直接向 APRS 网络推送消息，需要身份验证，需要业余无线电呼号和 passcode。passcode 的申请，请写一个申请 email 给 pete@ae5pl.net

$ nc 66.109.111.25 14580
# aprsc 2.0.0-gf5e3f21
user YOUR_CALL_SIGNE pass YOUR_PASSCODE -1 ver "manual login".net

成功后会看到服务器返回：

 # logresp YOUR_CALL_SIGNE verified, server FIFTH

3. 推送消息

YOUR_CALL_SIGNE>APDR12,TCPIP*,qAC,T2CSNGRAD::EMAIL     :aprs-go@gmail.com testing via aprs{1

很快你就能在推送消息的服务器监控页里： http://66.109.111.25:14501 看到有你呼号的那一行的 'Packets Rx' 列，记数加了一个

可以在这个地址直接查看：http://aprs.fi/?c=raw&call=YOUR_CALL_SIGNE 刚刚推送的消息
