今天
先和小叔听一段录音

就是下面这个玩意儿
发出的声音信号
它
干扰了
火腿在10米段的
通联
这鬼声音
火腿通联时能忍受？
所以
这群葡萄牙火腿
怒了
开始了自发寻找
害虫的行动
看完这篇文章
有小叔担心的事
还有个小调查

llegal GPS sea buoys on 10 meters Band ( 28 MHz )
非法10米段（28 MHz ) GPS浮标
A group of Portuguese amateur radio enthusiasts are spending their own vacation time trying to identify the location of a series of GPS buoy clusters that are transmitting, illegally and for years, on the 10 meter band.
一群葡萄牙业余无线电爱好者利用假期时间试图识别多年来在十米段非法发射的一系列的GPS浮标集群的位置。
“So far, we have had some success in determining the location of the few that we can receive when propagation allows. The data suggests that these clusters are located in the Atlantic, alongside the coasts of Africa and Europe but it´s possible that they are present elsewhere”, indicates Paulo Teixeira, CT2IWW.
Paulo Teixeira,CT2IWW表示：“到目前为止，我们已经成功确认少量浮标的正确位置，我们可以接收时传播。收集到的数据表明，这些浮标集群位于大西洋、沿着非洲和欧洲的海岸分布，但它们可能分散在各处”。
According to Paulo´s description, these transmissions consist of three second long F1B bursts(RTTY) at 51bd, 300 kHz shift. Individual transmissions are 10 seconds apart with the whole process repeating every five minutes. Frequencies are between 28000kHz and 28120kHz, at 5 kHz intervals.
根据Paulo描述，这些传输包括三秒时长的F1B破裂声(RTTY)51 bd，300 kHz转换。单个浮标传输10秒间隔，每五分钟重复整个程序。传输频率在28000 kHz和28000 kHz之间，5 kHz间隔。
“So far we detected them on 28010, 28025, 28035, 28050, 28065, 28075 and 28101 khz but we believe that other frequency ranges are possible”, advances the team´s spokesman.
该小组的发言人表示，迄今为止，他们在28010, 28025, 28035, 28050, 28065, 28075和28101 khz 检测到信号，但是他们认为在其他的频率范围也可能监测到GPS浮标的信号。
The group requests the assistance of the amateur community, particularly of those amateurs along the Atlantic, to look out for these transmissions and record them, since they are having a tough time getting more samples, due to lack of propagation.
这个团队需要业余无线电社群的协助，特别是沿大西洋的业余无线电爱好者，帮他们寻找这些传输信号并记录它们，因为由于缺乏传播条件，很难得到更多的样本。
“More recordings are needed in order to get greater consistency of the decoded data and, possibly, work on an automated or semi-automated decoding solution”, detailed Paulo, CT2IWW.
Paulo，CT2IWW详细的解释说：“为了使解码数据具有更高的一致性，我们需要更多的录音，可能工作在自动或半自动解码方案。”
According to the group, it´s important that the recordings indicate the date, start time UTC, frequency and mode, preferably in USB. Audio center frequency between MARK and SPACE should be kept as close as possible to 1500Hz to achieve grater consistency (eg. 28025kHz should tuned at 28023.5kHz USB). Recordings should be, at least, 10 to 20 minutes long.
根据该团队介绍，记录日期、开始时间UTC、频率和模式是非常重要的，最好是在USB模式。MARK 和SPACE 之间的中心频率应保持尽可能接近1500 hz以实现更好的一致性。28025kHz 应该调整28023.5 khz USB)。录音时长应该至少10到20分钟。
Results can be emailed directly to CT2IWW (email info on QRZ.COM) or, preferably, as a link to a cloud upload like Dropbox, Mega, etc.
可以将录音可以直接电邮给CT2IWW(QRZ.COM)或者上传到类似Dropbox, Mega等云端。

Search is On for GPS Buoys Intruding on 10 Meters
在10米段的GPS浮标搜寻还在继续
Radio amateurs in Portugal have intensified the search for GPS buoys that are illegally operating and intruding on 10 meters. A recent International Amateur Radio Union Region 1 Monitoring System (IARUMS-R1) report indicated that one such buoy was operating 24/7 on 28.100 MHz, using F1B mode (RTTY), 51 baud, 270 Hz shift. IARUMS-R1 also has posted a lengthy and growing list of intruding driftnet fisheries buoys, transmitting CW in various parts of 10 meters. A group of Portuguese radio amateurs has volunteered to identify the location of GPS buoy clusters that have been transmitting “for years” on 10 meters, an exclusive Amateur Radio allocation.
葡萄牙业余无线电爱好者正在抓紧寻找非法操作入侵10米段的GPS浮标。最近的一次国际业余无线电爱好者联盟1地区监测系统(IARUMS-R1)报告显示其中一个浮标在24/7 28.100 MHz操作，使用F1B模式(RTTY)，51波特，270 Hz转换。IARUMS-R1还发布了一个冗长的和越来越多的在10米段发射CW信号的入侵者——漂浮渔业浮标。一群葡萄牙业余无线电爱好者自愿识别多年来一直在10米段传播的GPS浮标集群的位置，这些浮标的发射独立于业余无线电分配。
Meanwhile, Jose Francisco de Almeida, CT4AN, reported that agents from Portugal’s telecoms regulator ANACOM and maritime police inspected 30 fishing, maritime tourism, and passenger vessels in Madeira, Douro, and Cascais, for illegal radio gear. According to IARUMS-R1, the two agencies have undertaken several enforcement actions in commercial fishing ports and marinas. Violations detected included the use of inadequate equipment or radio equipment operating outside the maritime mobile service bands. Twelve ANACOM and 14 maritime police took part in the operations, which were reported to have resulted in a decrease in offenses.
同时，Jose Francisco de Almeida, CT4AN的报告指出，葡萄牙电信监管机构ANACOM和海事警察搜查了马德拉、杜罗河和Cascais上的30艘渔船、海上旅游船和客运船舶上安装的非法无线电装置。根据IARUMS-R1，这两个机构已经在商业捕鱼港口和码头进行多次执法行动。违规搜查包括电台设备配备不足或配备的无线电设备在海上移动服务频段之外的超范围使用。12个ANACOM工作人员和14名海上警察参与了行动，该行动将减少海上渔业电台违法行为。

不过话说回来
小叔认为
打浮标
别打到潜艇释放的通信浮标
那就妈妈咪呀了！
看昨天的推送
↓↓↓
【无线电史话】苏联提出的在中国建立长波电台被拒，请问长波电台存在的意义是什么呢？
因为潜艇除了长波通信也会释放浮标来对外通信啊！
此浮标非彼浮标啊！
