Jarvis Island N5J DXpedition
August 5, 2024 to August 17, 2024

Dear Fellow DXers,

The Dateline DX Association is pleased to announce it has received permission from the USFWS for a DXpedition to Jarvis Island National Wildlife Reserve this August. Jarvis is ranked nr. 19 on Clublog's global most wanted list. It is number 9 in Europe. Jarvis is ranked higher than Bouvet (16) in Europe. It is 450 miles from Palmyra Atoll and 1500 miles from Hawaii.

A small but experienced team of four consisting of George, AA7JV, Don, N1DG, Tomi, HA7RY and Mike, KN4EEI, will install 6 RIB stations on Jarvis. The at-island team will be augmented by 24 remote operators from Asia, Europe and North America. They will operate on 160 to 6 meters using CW, SSB and FT8 modes. We are permitted 12 days of operation.

This DXpedition will make every effort to work stations from around the world and focus on providing an all time new one by maintaining one station on 20 meters throughout the visit.. The core of the Dateline DX Association is the team of operators from the highly successful Baker Island 2018 and Midway 2009 DXpeditions. Both DXpeditions received the coveted DXpedition of the year awards at Dayton. We have broad experience working from the Pacific and remote and environmentally sensitive areas around the world. It was this experience that earned Dateline the first permission to activate Jarvis since 1990. This will be the third operation from Jarvis.

Any DXpedition to a protected area is expensive and our externally financial need is over $200,000. We have a boat, approved by the US Fish and Wildlife Service, to safely carry us to and from the Reserve and not cause any harm to Jarvis Island or the surrounding reefs. The budget would easily have been over $500,000 had it not been for the use of AA7JV’s vessel, the Magnet. The $200,000 is required for fuel, USFWS permit fees, extra crew for the trip and data services and equipment. Radios are not included in the budget as NCDXF contributed to the design and building of the RIBs.

NCDXF has also kickstarted our fundraising campaign with a hefty grant of $75,000.

Please understand the dates for our DXpedition were not our first choice. Rather, the exact dates of our DXpedition were specified by the U.S. Fish and Wildlife Service. While top band opportunities are limited by the early August dates, 10 and 6 meters should offer ample opportunities to pick up new band counters. Europeans (where Jarvis is number 9) should benefit greatly for ATNO QSOs during the peak months of cycle 25.

There will be extensive science being conducted on Jarvis by 3 biologists from the USFWS. We will be providing free transportation and food for their team.

You can follow our plans on our web site at: http://jarvisisland2024.com, and on Facebook.

We are counting on help from DXers and DX organizations from around the world to help cover our costs. Jarvis has not been activated for 34 years and we anticipate by demonstrating our RIB concept to the USFWS biologists accompanying us to Jarvis we can open the doors to other islands off limits to the ham community.

何これ ？ - Gyp

JTDXのウオーターホールの左端にザラザラノイズが見える、何これ？

ハムが乗ってる？/デコード時のノイズ？
1. バンドチェンジやアンテナを抜いても発生します。
2. フィルターで低域カットするとノイズは抑えられるが周波数の高い方にノイズがシフトします。

データケーブルのコネクターの抜き差しやケーブル交換したが変化なし・・・いろいろ悩んだ末、ウォーターホールの設定「Start 0Hz」→「Start 100Hz」に変更したらノイズはきれいさっぱりとなくなりましたよ

PC(Win 10)が古くなり、「Start 0Hz」設定時にPCの電源ハムが見えているのかもHi

この前のCB0ZシリーズでCB0ZAがLoTWにアップされていました。　他のエンティティも含め、デジタルのエンダーズメントを申請するかどうかは、＄高￥安のせいで迷っている所です。

CQ Zone 2 17m FT8 です。

JTDX で背面が金色だったので Zone 2 かもと QSO やはり当たりでした。

相変らず Low Bands IV ANT + IC-7300 内蔵チューナー ON 50W DF 選びがポイントでした。

日々の暖気でLow Band用の受信アンテナK9AYを工作してみようかと「NanoVNA-H4 ベクトルネットワークアナライザー4インチLCD 10k-1.5GHz」(￥8,353)をポチって見ました。
K9AY工作結果は・・・？
