122 GHzで新しい世界距離記録を獲得 ≪New
World Distance Record Claimed on 122 GHz≫
ARRL
02/21/2020
A new world distance record of 139 kilometers
(86.2 miles) is being claimed by radio amateurs
in northern California. This tops the record
of 114 kilometers set in 2005 by WA1ZMS and
W4WWQ, according to the Distance
Records on the ARRL
website.
The February 17, 2020, contact was between
Mike Lavelle, K6ML, on Mount Vaca (CM88WJ75ON)
at 835 meters (2,739.5 feet) above sea level,
and Oliver Barrett, KB6BA (at 1225 UTC), and
Jim Moss, N9JIM (at 1250 UTC), both on Mount
Umunhum (CM97BD18VJ) at 1,016 meters (3333.3
feet) above sea level.
Lavell reports the dew point was -11 °C, the
air temperature was 15 °C, the path loss was
about 225 dB, and atmospheric loss was approximately
0.35 dB/kilometer.
“CW was used, 122 GHz signals were very weak
(7 dB above the noise in 22 Hz; -13 in 2500
Hz equivalent) with [fading] down to the noise
floor,” Lavelle told ARRL. “Dishes were aligned
on 24 GHz (71 dB above the noise) prior to
[moving] to 122 GHz; we heard signals right
away on 122 GHz.” The stations employed 60-centimeter
satellite TV dishes and ran “somewhat less
than half a milliwatt” on 122 GHz, Lavelle
said.

World Amateur Radio Day ≪Date：April
18, 2020 Time： All Day≫
International
Amateur Radio Union
Every April 18, radio amateurs worldwide take
to the airwaves in celebration of World Amateur
Radio Day. It was on this day in 1925 that
the International Amateur Radio Union was
formed in Paris.
Amateur Radio experimenters were the first
to discover that the short wave spectrum???far
from being a wasteland???could support worldwide
propagation. In the rush to use these shorter
wavelengths, Amateur Radio was “in grave danger
of being pushed aside,” the IARU’s history
has noted. Amateur Radio pioneers met in Paris
in 1925 and created the IARU to support Amateur
Radio worldwide.
Just two years later, at the International
Radiotelegraph Conference, Amateur Radio gained
the allocations still recognized today???160,
80, 40, 20, and 10 meters. Since its founding,
the IARU has worked tirelessly to defend and
expand the frequency allocations for Amateur
Radio. Thanks to the support of enlightened
administrations in every part of the globe,
radio amateurs are now able to experiment
and communicate in frequency bands strategically
located throughout the radio spectrum. From
the 25 countries that formed the IARU in 1925,
the IARU has grown to include 160 member-societies
in three regions. IARU Region 1 includes Europe,
Africa, the Middle East, and Northern Asia.
Region 2 covers the Americas, and Region 3
is comprised of Australia, New Zealand, the
Pacific island nations, and most of Asia.
The International Telecommunication Union
(ITU) has recognized the IARU as representing
the interests of Amateur Radio.
Today, Amateur Radio is more popular than
ever, with more than 3,000,000 licensed operators!
World Amateur Radio Day is the day when IARU
Member-Societies can show our capabilities
to the public and enjoy global friendship
with other Amateurs worldwide. We have provided
a poster for World Amateur Radio Day. Any
club may download it and use it to promote
WARD in their area. The poster comes in two
sizes: 61cm x 91cm and a small (A4) flyer.
今日、アマチュア無線はこれまで以上に人気があり、3,000,000以上のライセンスを受けたオペレーターがいます！
世界アマチュア無線の日は、IARUメンバー協会が一般に私たちの能力を示し、世界中の他のアマチュアとのグローバルな友情を楽しむことができる日です。
世界アマチュア無線デーのポスターを提供しました。どのクラブでもそれをダウンロードし、それを使用して自分の地域でWARDを宣伝できます。ポスターには、61cm
x 91cm と 小さな（A4）チラシの 2つのサイズがあります 。
グループは 、TwitterおよびFacebookでハッシュタグ#WorldAmateurRadioDayを使用して、ソーシャルメディアでのWARDアクティビティ
を促進する必要があります。IARUは、このページにすべてのWARDアクティビティをリストします。WARDアクティビティをリストするには
、K1ZZのIARU 秘書 David Sumnerにメールを送信してください。 4月18日は、アマチュアラジオのすべてが、私たちが教えるのに役立つ科学、私たちが提供できるコミュニティサービス、そして私たちが持っている楽しさを祝い、世界に伝える日です。
世界アマチュア無線の日である楽しさと教育に参加することを願っています！2020年のテーマは「社会へのアマチュア無線の貢献を祝う。」されます
EchoLinkの世界会議とIRLP 9251は、午前12時4月19日まで午前12時から土曜日4月18日に世界アマチュア無線の日を祝うの助けになるだろう番目。特別なイベントコールサインはW7Wになります。チェックインできることを願っています。ー

sites can be accessed directly from the IARU
home page. All of the updated pages are organized
to broadly mirror the structure of the International
Telecommunication Union (ITU)
and its related regional telecommunication
organizations. The IARU regions are Region
1 ? Europe, Africa, the Middle East, and Northern
Asia; IARU Region 2 ? The Americas, and IARU
Region 3 ? Asia-Pacific. The Region 2 web
