天线不好，一直也没有机会上去，寄去了一个swl卡，大致符合3b7c的要求，希望能得到回卡：
these few simple guidelines will help swls provide good quality reports:
- log three consecutive qsos on all bands/modes where possible
- multiple loggings qsos must be listed in date and time (utc) order
- provide honest, accurate reports
- make sure your swl card is written clearly and neatly
- to avoid mistakes, take your time in filling in your qsl card
- make sure that your report shows the correct date and (utc) time
- make sure your report has all the necessary details: date, time (utc), band, mode, report and the callsigns of three stations worked by 3b7c
