2024-08-28 11:12:30 UTC，使用G90在21.074MHz遇到了正在用FT8模式CQ的联合国维也纳国际中心电台4U1A，随即通联。完成了信号报告和RR73的步骤，但后续未完成73，只好手动确认。不知道对方会不会确认通联然后上传LoTW呢？

科普一下，4U1A的DXCC识别为奥地利，DXCC识别为UN的是4U1UN [upl-image-preview url=https://storage.hamcq.cn/2024-08-28/1724866310-261534-image.png] 还有，如果你跳过TX1那么对方发73才会触发记录动作，如果你没跳过TX1，那么是对方先触发记录动作。

看对面有没有收到你发送的rr73了，有的台收到rr73后不会回复73而是继续下一个通联

4U1A常见，比较容易通，4U1UN一般般天线连收到都难

这个台好捅，QSL卡3美刀，貌似不传lotw。我9号捅了他，现在还没传。

一个多月之后，4U1A在LoTW上确认了。

@"Ken"#p35417 挺好的我这有个整整一年才确认的，笑死

The FT8 communication was established with the 4U1A located in Vienna, Austria, under the auspices of the United Nations.

2024-08-28 11:12:30 UTC, using G90 on 21.074 MHz, I encountered the United Nations Vienna International Centre radio station, 4U1A, which was operating in CQ mode under FT8. I then established contact. I completed the signal report and RR73 steps, but did not complete the subsequent 73, so I had to manually confirm. I'm wondering if they will also confirm the contact and upload to LoTW?

Check if any of the stations you're communicating with have received your RR73 message. If a station receives the RR73, it will not reply with "73" but continue to the next communication.

科普一下，4U1A的DXCC识别为奥地利，DXCC识别为UN的是4U1UN

还有，如果你跳过TX1那么对方发73才会触发记录动作，如果你没跳过TX1，那么是对方先触发记录动作。

4U1A is common and relatively easy to connect, while 4U1UN is generally difficult to connect.

This station is very difficult to contact. The QSL card costs $3, and it seems that I haven't been able to send a confirmation through LotW. I contacted him on the 9th, but I still haven't received confirmation.

Ken

After several weeks, 4U1A was confirmed on LoTW.

Ken Very good
I just found out, after a whole year, and I'm dying of laughter!
