3Y0J: FINAL PRESS RELEASE (13 APRIL) ---> "With this Final Press Release the
team want to express gratitude to all our sponsors that generously supported
our Bouvetoya adventure. Without the upfront support this trip would simply
not be possible.
We announce today that we have decided to refund $50,000 of the donations to
the DX community.
One month before we departed Falkland Island, we informed the DX community
we had financed our budget. We have continued to receive a great amount of
financial support up until now. This way we can reduce the $25,000 operator
fee, and at the same time we are able to refund the DX community.
We have decided to refund our Lead Sponsor NCDXF with $40,000. Initially
NCDXF supported the team with their largest grant ever $100,000. It is with
pleasure we can give back as much as 40% of the donation to them.
We will distribute the rest of the refund among our major club sponsors who
all stepped up and donated generously to this DXpedition.
We will refund the following clubs and organizations with apprx. 10% of
their donation: GDXF $3,000, INDEXA $1,000, ARRL Colvin Award $500, NIDXA
$500, FEDXP $500, TCDXA $500, SEDXC $500, LADX group $300, Clipperton $300,
South Carolina $300, Chiltern DX Club $300, IOTA $300, Delta DXA $300. Thank
FO/AA7JV ---> On 10 April Northern California DX Foundation Directors suc-
cessfully concluded their 11-day ground-breaking experiment from Tikehau
Atoll in the Tuamutu Islands, French Polynesia, with a remotely operated
DXpedition. While FO is not rare for DXCC, Tikehau (OC-066) was needed by
72% of the active IOTA chasers.
George, AA7JV and Mike, KN4EEI Mike, arrived at Tikehau on the morning of
28 March and deployed two RIBs (Radio In a Box) in a matter of hours. In
addition to their CW and SSB QSOs done locally (from the ship), a total of
over 11,000 FT8 QSOs were completed remotely. The remote operators were
N1DG, AA7A, K6MM, K6GFJ and ND2T. The station was accessible 24/7 using home
computers and desktop sharing software. No specialized hardware or software
was required. The operators were working from their homes in shifts, just
like on a regular DXpedition, without the cost and hassle of traveling.
This operation did not use any unattended operation (as required by ARRL
DXCC rules). All callsigns were selected by the operators for a QSO.
The remotely operated stations were connected to the Internet via a Star-
link satellite connection. Operating mode was FT8 and FT8 F/H. The radios
were Flex 6700 radios housed in the NCDXF sponsored RIB stations that were
put ashore by AA7JV and KN4EEI. Operating power was 100 watts and each sta-
tion had its own vertical antenna. AC power was provided by Honda EU2100
generators running in the ECO mode. The stations were on the island unat-
tended, with remote supervision and control from the catamaran "Magnet",
which was anchored a mile off-shore.
The NCDXF RIB is a complete, fully wired station in a weather-tight box.
The RIB integrated a Flex 6700 SDR radio, an amplifier, power supplies and a
comprehensive Raspberry Pi based control system developed by KD4Z. The RIBs
were designed to eliminate the need for camping and to make DXpedition set-
up faster (hours, instead of days). For more information on the RIBs see the
NCDXF Winter newsletter at https://www.ncdxf.org/pages/newsletter.html.
In this Remote DXpedition experiment a dual-radio version of the RIB was
used, which contains two complete 100 W stations in a single box.
A RIB will be shown at the NCDXF booth at the International DX Convention
in Visalia (22 April), and plans are also being made to allow convention
goers to operate the RIB Friday evening.
In development and testing since early 2022, the NCDXF Remote RIB technol-
ogy is aimed at future DXpeditions. It is intended to enable remote opera-
tors to participate in DXpeditions without the expense and lengthy travel
usually involved. Kevin Rowett, K6TD, President of NCDXF commented: "remote
DX operation will bring the opportunity to participate in DXpeditions and
share the excitement of handling the pile-ups to a wide range of radio
amateurs. It will also allow future DXpeditions to have a smaller number of
on-site operators, reducing the expenses and footprint of future DXpedi-
tions". Ken, WZ0L wrote us: "Now that's the way to activate an island".
The NCDXF mission is to make DX happen. The NCDXF has been aware for some
time that financing is not the only obstacle faced by would be DXpedi-
tioners. The NCDXF has sponsored the development of the RIB technology to
lower the threshold of obtaining landing permits to ecologically sensitive
Later in 2023 the "Magnet" hopes to visit other DX locations, including an
entity or two in the top 20 most wanted. We trust this just concluded oper-
ation is one of the final steps in demonstrating to the permitting services
that limited intrusion to the island is possible and Amateur Radio can be
made eco friendly.

INTERNATIONAL MARCONI DAY ---> Organized by the Cornish Radio Amateur Club,
the International Marconi Day (IMD) is a 24-hour amateur radio event held
annually to celebrate the birth of Guglielmo Marconi (25 April 1874). It is

contacts with historic Marconi sites using HF communications techniques.
This year's event will be held on 22 April, from 00.00 UTC to 23.59 UTC.
Details, including information on the Award Certificates and the listing of
