2024年腓特烈港国际业余无线电爱好者展览会

腓特烈港欧洲国际业余无线电爱好者展览会（HAM RADIO）是欧洲最大的无线电技术及设备展览会，是国际上最大的无线电业余爱好者展览会，该展从1976年开始，一年一届，在腓德烈港举行。来自欧洲各地及世界其它各地的无线电业余爱好者参加，是无线电技术发展驱动器，展期三天，展览的无线电技术，电子产品，互联网络，计算机等相关技术产品。

HAM RADIO展每年有来自30多个国家的近200家企业参展，吸引来自全球近2万名无线电爱好者参加，展会涉及：地面无线电波传输技术及应用、水上无线电波传输技术及应用、空中无线电波传输技术及应用。展期举行各种技术与交流讲座，青年爱好者指导与培训。

无线电爱好者

在无线电领域里，有着一群特殊的群体，被称为“火腿族”，英文HAM。他们不是专门从事无线电工作的，却掌握了一定电子技术学习、制作、使用无线电，以对无线电的学习、应用和掌握从而对其产生的乐趣，实现生活、学习和工作的简单问题。

无线电是近代发展起来的，无线电是指在自由空间传播的电磁波，其频率300GHz 以下。无线电技术是通过无线电波传播信号的技术。无线电技术的原理在于，导体中电流强弱的改变会产生无线电波。利用这一现象，通过调制可将信息加载于无线电波之上。当电波通过空间传播到达收信端，电波引起的电磁场变化又会在导体中产生电流。通过解调将信息从电流变化中提取出来，就达到了信息传递的目的。麦克斯韦于1861年至1865年之间在他递交给英国皇家学会的论文《电磁场的动力理论》中阐明了电磁波传播的理论基础。海因里希·鲁道夫·赫兹在1886年至1888年间首先通过试验验证了麦克斯韦尔的理论。他证明了无线电辐射具有波的所有特性，并发现电磁场方程可以用偏微分方程表达，通常称为波动方程。1906年圣诞前夜，雷吉纳德·菲森登（Reginald Fessenden）在美国麻萨诸塞州采用外差法实现了历史上首次无线电广播。菲森登广播了他自己用小提琴演奏“平安夜”和朗诵《圣经》片段。位于英格兰切尔姆斯福德的马可尼研究中心在1922年开播世界上第一个定期播出的无线电广播娱乐节目。无线电爱好者就是在这些方面发挥推动性的作用，正因为他们的作用，无线电的发展才会逐步推进。

展会报告(Show Reports):

Friedrichshafen – It was that time again over the weekend: Antennas, radio equipment, brand-new transmitter and receiver systems, and a varied accompanying program on STEM (science, technology, engineering, and mathematics) subjects attracted 11,100 visitors to the fairgrounds in Friedrichshafen. Radio fans from 59 countries came together to celebrate their annual international reunion and to use the Ham Radio as a platform for sharing ideas. “The Ham Radio lived up to its reputation as Europe’s largest amateur radio exhibition. In cooperation with the German Amateur Radio Club (DARC) as the perfect partner for the event, we showed that amateur radio plays an important role in society. This year’s slogan ‘We’re all about STEM!’ was brought to full fruition, with many activities focusing on work with young people, something that really brought in the crowds,” say Messe Friedrichshafen Managing Director Klaus Wellmann and Project Manager Petra Rathgeber, who were delighted with the success of the event. A total of 392 participants, including 149 commercial exhibitors and international associations as well as 243 flea market exhibitors, represented the great diversity of the radio world.

You could sense STEM fever in all three halls, Foyer West, and Open-Air Area West. Science was everywhere you looked, from lectures on the basics of computer science and radio technology to the launch of the stratospheric balloon and teacher training. On Friday, some 140 teachers had the chance to acquire the latest knowledge for engaging in practical, hands-on instruction in schools. Another highlight of the exhibition was the experimental balloon launch on Saturday morning. Hundreds of people interested in radio gathered at Open-Air Area West to eagerly await the ascent of the specially designed flying object, which began with a countdown. They then traced its journey in real-time by following along with the transmission in Foyer West.  

Visitors could also check out other radio experiments at the German Amateur Radio Club’s newly designed booth. Children and young people were able to tinker about and make things there under guidance, as well as test their knowledge at the Ham Rally. The return of the technical scavenger hunt featured 25 stations. The young amateur radio fans were able to try their hand at Morse code, assemble technical kits, pass the QSL card quiz, and reach out to astronauts on the International Space Station. Christian Entsfellner, Chairman of the German Amateur Radio Club, was also quite pleased with the success of the Ham Radio: “We are really happy with the way this year’s exhibition went. We especially liked the international flair of the event and the great atmosphere over the last three days. We were also able to perfectly stage the slogan “We’re all about STEM!” with our new booth concept, individual knowledge focal points, and innovation stands. With all of this, we demonstrated that we are very much in sync with the spirit of the times. The importance of amateur radio for society was also illustrated by the signing of the new Amateur Radio Ordinance by Federal Minister for Digital Affairs and Transport Dr. Volker Wissing just in time for the Ham Radio. We are very excited that there will be a new entry-level class in the future, and that remote operation will be simplified.” For the coming year, the German Amateur Radio Club plans to further promote youth work as well as training and continuing education. 

The long-time radio amateurs also experienced a unique radio adventure. In addition to do-it-yourself antenna building, numerous workshops, expedition presentations, and the treasures to be found at the flea market, there were new products and many different exhibitors to discover in Zeppelin Cat Hall A1. Compared to last year, 15 percent more commercial exhibitors and international associations (previous year: 129) participated in Ham Radio 2023.  

In the discussions, many exhibitors had very positive things to say about how this year’s exhibition went. Michael Bürck, Sales Communication at JVC Kenwood Deutschland GmbH, provided the following summary: “We are very satisfied with the exhibition and had many good conversations. We rolled out our new THD75 E handheld radio this year, and the response to the product was very good. Here at the booth, we met visitors who were both international and very savvy. The Ham Radio is one of the three big trade shows for us, so it’s absolutely vital for us to take the opportunity to present ourselves and speak with the public at this venue.” Thorsten Chmielus, Chief Executive Officer of Aaronia AG, was also very satisfied with the exhibition: “Our first Ham Radio participation went really well for us, especially the presentation of our SDR product and our sales activities. We were literally overrun with visitors. The decision to present at the Ham Radio turned out to be extremely worthwhile for us, and we will be coming back every year in the future.” Bonito owner Dennis Walter also expressed great anticipation for Ham Radio 2024. “We were thrilled with Ham Radio 2023. It had a good atmosphere that was both positive and relaxing. The visitors took such an interest in our products that we had sold out of some of them already on Friday. Our new concept with the workshops also worked out perfectly. All of them were fully booked. We’re already looking forward to next year’s exhibition.”  

It wasn’t just the exhibiting companies but also the international associations who were pleased with the Ham Radio as a meeting place for amateur radio. “For the Ham Radio, our focus is on speaking with a lot of members, retaining them, and attracting new members. All the work we do here is to be understood under the heading of ‘fostering international understanding,’ which is what the Ham Radio is all about. Visitors from all five continents are here, making it an international event of the highest order. Contacting people by radio and Skype is always possible, and that was also the case during the coronavirus pandemic, but there really is no substitute for chatting live and in person!” says Prof. Dr. Achim Rogmann, Chairman of the association EUDXF.  

The next Ham Radio will be held again in Friedrichshafen, Germany, from Friday, June 28, to Sunday, June 30, 2024.
