/**
|
||
* 用于计算和处理SWL消息中的QSO记录。
|
||
* QSO的计算方法：把FT8通联的6个阶段分成3部分：
|
||
* 1.CQ C1 grid
|
||
* 2.C1 C2 grid
|
||
* ---------第一部分---
|
||
* 3.C2 C1 report
|
||
* 4.C1 C2 r-report
|
||
* --------第二部分----
|
||
* 5.C2 C1 RR73(RRR)
|
||
* 6.C1 C2 73
|
||
* --------第三部分----
|
||
* <p>
|
||
* 一个基本的QSO，必须有自己的结束点（第三部分），双方的信号报告（在第二部分判断），网格报告可有可无（第一部分）
|
||
* 以RR73、RRR、73为检查点，符合以上第一、二部分
|
||
* swlQsoList是个双key的HashMap,用于防止重复记录QSO。
|
||
* C1与C2顺序不同，代表不同的呼叫方。体现在station_callsign和call字段上
