Are you calling me? Please use my call sign if you answer my CQ call!
If you call me for windle-points only in regular terms and never else, safe our both´s time! I don´t join that nonsense.
Sending a "?" to find out who was calling is complete crap! Wait and copy the call-sign! Doing so is actually not just unprof but also rude!
QRP is waste of time. I prefer arm-chair communication if conds permit.
You like FT8? I don´t!

Welcome to Wallis Island DXPedition OC-054, Grid AH-16 put on by the DX Obsessed Group.

Update 27-October-2025

OQRS has been restored. Please follow the instructions in OQRS for online and direct QSLing. Thank you to all who informed us of the QSL services not working properly. See you in the pile ups. Marc FW5K

Update 26-October-2025

We have temporarily disabled clublog OQRS due to a isssue with PayPal As soon as the issue with PayPal is resolved we will update this space and reenable the QSL service.

73 Marc NC7M FW5K

Dates of Operation 19-October-2025 thru 31-October-2025. We land on 18-October, but we will have travelled for nearly 20 hours. We will take a rest period and be up and running soon after. We will represent Wallis and Futuna Islands in the CQWW SSB Contest

Please check our website dxobsessed.org for updates, operating frequncies and daily journal entries. We will be operating 24/7 once we are up and running. Look for us on 6, 10, 12, 15, 18, 20, 30, 40, 60, 80 and 160 meters.

QSL Information - We will upload to ClubLog Daily

Please see ClubLog OQRS. This is the preferred method due to the volume of QSL requests.

NO BUREAU CARDS - It is to expensive due to the sheer volume of QSL request we receive. Thank you for understanding.

Complete LOTW upload after 9 months at the latest.

Modes :

CW, SSB, RTTY, FT8/4

Please check this space and our website for updates.

Please check the website for details and operating frequencies DX Obsessed Group

Thank you, See you in the pile-ups.

Update 21October2025

"All FW5K logs were uploaded to Clublog. Please check all QSOs before attempt working is again and crating dupes. The internet is slow with many interruptions, so not all QSOs are uploading immediately. Please allow 24hrs to update logs and check Clublog. EU is priority to FW5K and we will try to operate on low bands in most convenient time as possible. 73, FW5K team "

September 2025: FYI: Intesersting Video YouTube from 11 Jan. 2024 (US, Dayton OH ) on HAARP (The High Frequency Active Auroral Research Program by Chef Eng. Steve Floyd (W4YHD): Facility in Alaska covers DC to Light, focus on HF 2.6MHz to 10MHz with 180 Cross Broadband Dipole Array, each 10kW TX and 5GW ERP. Low Frequency Modulation can stimulate ionospheric effects down to extremly low frequencies for research.

August 2025: We will hopefully soon publish (submitted to major EMC Symposium EU):
"TEMPEST (UHF RX Spurs) remotely trigger wireless HF-IEMI Attack on a tuned commercial HF-Receiver"
Abstract: A bizarre and complex, malicious shortwave (HF) - Jamming (DQRM, IEMI) attack scenario got TEMPEST/COMSEC/EMSEC analyzed. Our 4 selected commercial Amateur Radio Transceivers (TRX) are all EU CE-RED compliant. These high-class models are 3x K3S Elecraft USA, 1x FTDX101MP YAESU, Japan. Conducted Receiver (RX) Antenna Port-Emissions (ETSI limit -57dBm, 50Ohm) were measured from 150kHz to 1GHz. The actual, most relevant, internally generated HF-VFO/Synthesizer UHF/VHF and HF Spurious RX Ant. Port Emissions (weak signals) are identified in frequency groups and amplitude. A clear correlation of HF-VFO (HF-communication channel) frequency setting and following tracking UHF Spurs, a potential info leakage, is demonstrated. UHF/VHF/HF Signal propagation with path loss estimation, in the nearby HB9CVQ author’s radio installation environment, was experimentally/theoretically checked. The unknown, temporary HF-Jammer location was estimated to be between 50 to 300m, in roughly northern direction. In a commercial/military scenario, however, VFO-setting, by recovery from information leakage, could have much more critical consequences

My comments: Very good and important works mapping Noise in 2D. The next step should be 3 dimensional mapping (drones). Assuming roughly avg. -40dBi (+/- 15dB) antenna gain by house LV installations, there is probably a vertical radiation pattern that matters.

Measuring radiation efficiency of electrically small, automotive-on the move, short-wave antennas,

including lessons learned for restricted space antenna (160/80/40m) optimization.

Dr. Diethard (Andy) Hansen (Ph.D.) HB9CVQ, DK2VQ, AK4IG

Advanced Presentation Slide (63 pages PDF) Download The idea here is to help potential participants to decide/master/profit maximally from this "Crash Course".

The slides serve only as a navigator through the talk, being not comprehensive without listening. In the session we can increasingly elucidate "why" and "how (DIY)". On-site discussions may include very latest research findings.

Structure/Topics:

There are direct implications of this, aside from Military/ Special-Forces/ Government, in mobile HAM RADIO and NGOs. Humanitarian-medical-technical crisis-relief organizations, with mission critical emergency communication needs, possibly in remote disaster areas, may also profit from our practical R&D.

Motivation, Background, R&D Project Goals
State of the Art in HAM RADIO and Commercial +(Mil) ESA (Electrically Small Antennas)
Some Basic underlaying EM-Physics/Theory of ESA (Verticals, Loops)
Methods of Testing Antenna Radiation-Efficiency, go/no-go Metrology.
Need for Professional Simulations (Model: interaction Car, Tires, ESA, Soil, etc.)
Creating 160/80/40m ESA Reference-Antennas, comparing Simulation and Testing
Absolute “Gain” comparison by means of predictable Reference-Antennas (using EM-Simulations)

Resulting Antenna-Efficiency impacting factors (soil on low bands, elevation angle, design etc.) Conclusions, Project Outlook (future R&D topics), open Literature
