  • E7POTA – Special Callsign for Parks on the Air (POTA)

    The special callsign E7POTA from Bosnia-Herzegovina is now active on the HF bands for the Parks on the Air (POTA) program.

    E7POTA and OE/E7POTA will be active across the HF bands on SSB and FT8/FT4. Keep an eye on the POTA cluster HERE (link opens in new tab) for information. The callsign is also active on Facebook and you can follow them HERE (link opens in new tab).

    An award scheme for the special callsign is also available, awarding diplomas for making QSOs with the station. Details of the award scheme is available on their website HERE.

    I am pleased to have received the Bronze Award so far, and I will continue to work the callsign in their POTA activations.

    E7POTA Bronze Award – M7OJA. Thanks to E7POTA

  • Sunday 9th March 2025

    Despite a minor solar storm causing disruption and poor propagation on HF, I enjoyed operating today. I achieved 200 QSOs on Sunday, including 60 Youngsters on the Air (YOTA) contacts, 11 Parks on the Air (POTA) contacts and a new DXCC (Cocos Keeling Island) on 20m SSB.

  • Youngsters on the Air (YOTA) Contest 2025

    On Sunday 10th March 2025, the first round of the Youngsters on the Air (YOTA) contest took place. The aim of the contest is to provide an opportunity for young people (under age 25) to be the focus of a contest. For 12 hours, amateurs all over the world made contact with each other, with bonus points available for QSOs with under 25s.

    I chose to take part in the “6 hour” category of the contest, and as I am 21, I am classed as a “YOTA” station. In between other things, I put a few CQs out on 20m and 40m and finished the contest with 60 in the log. The oldest operator I spoke to was 82, and the youngest was only 7 years old operating with a youth club in Hungary!

    Log submissions are to be in Cabrillo format and can be submitted HERE (link opens in new tab).

    A few statistics from my log is below:

  • First RSGB FT4 Contest – A disaster story (or not?!)

    Last night, the 24th Feb 2025, I took part in the RSGB FT4 contest for the first time. I was using a 20.5m 49:1 end-fed. As the contest began, my strategy was to start on 20m for any DX contacts before moving on to 40m for as many European DXCCs as possible.

    Within about 5 minutes of the contest starting, I realised I wasn’t going to get far on the 10w I was using to enter into the “10w Restricted” category, so I increased my power to the maximum 25w as permitted by my licence. This meant I was able to achieve more points and countries, but this was a disadvantage as I had to enter in the 100w category.

    My first contacts as the contest began were to the USA, Morocco and the Canary Islands before moving on to 40m. Unfortunately, I do not have access to 80m at my home QTH, meaning I was unable to collect DXCCs from this band.

    On 40m, I was slowly but surely beginning to collect DXCCs, until my computer crashed and I had to restart before JTDX would work again. This set me back around 10 minutes.

    Owing to a couple of last minute DXCCs, I finished with 40 QSOs and 25 DXCCs in the log, which was nowhere near the highest score, but still fun to participate and nice to gain a couple of new countries on FT4.

  • Very Good Weekend on HF

    Due to the activity of Solar Cycle 25 and a high SFI and Sunspot count, the HF bands have been particularly good this weekend.

    I took full advantage of the good conditions this weekend and operated over a variety of modes and bands on HF from Friday to Sunday.

    To summarise my activity:

    Total In The Log (ITL)575 QSOs
    New Countries (DXCCs)9 New (Nigeria, Trinidad and Tobago, Bahrain, Armenia, French Guiana, Thailand, Dominica, St Vincent and the Grenadines, Belize)
    Total Countries (DXCCs)70 ITL This Weekend
    Parks on the Air (POTA) References10 References
    Bunkers on the Air (WWBOTA) References2 References

    A statistical view of my weekend activity is below, showing my overall statistics, a list of worked countries, a map of Europe and a worldwide map.

    General Statistics 21/02/25 – 23/02/25
    Countries (DXCCs) Worked this Weekend
    European Map
    Worldwide Map

    I have been lucky enough to work the DXPedition to Nigeria this weekend and a bonus contact as I am writing this to 4S7SPG, DXPedition to Sri Lanka.

    Always take advantage when the bands are strong, as you never know what DX is possible with a limited setup.

  • Daily Snapshot – 21/02/2025 on HF

    The bands have been remarkably open over the past week or two. In the past few days, there have been many DX opportunities on 10m, 20m and 40m particularly. Please see the snapshot of today’s activities.

    Working Conditions

    Between 5W-25W into an end-fed antenna (49:1, 20.5m wire) positioned over the roof. Transceiver is a Yaesu FT-991a.

  • Good Working Conditions on HF

    This week especially, working conditions on HF have been a lot better than usual. Even with a very modest antenna and low power, DX contacts have been achievable. This has also been helped by a range of DXpeditions at the moment, increased portable activity through schemes such as Flora Fauna (WWFF), Parks on the Air (POTA) and Summits on the Air (SOTA). There have also been several special event stations running recently.

    The most important factor, however, is the fast approaching peak of Solar Cycle 25, giving us improved propagation and many DX opportunities.

    You can see my daily snapshot HERE to see for yourself!

    DXpeditions

    At the moment, there are two major DXpeditions running. The first is V73WW, Marshall Islands. The second is VK9XU, Christmas Island. The links to both of their websites are below:

    V73WW

    VK9XU

    Special Event Stations

    There are a number of special event awards, provided by the Hamaward system. With this system, QSOs are automatically uploaded by the DX station (you do not need to submit your logs or QSL cards). Over the course of the award, you can work each participating callsign once per band, mode and day. This means you can accumulate a number of points per day. At the end of the award, your points are added up, and there is a feature to download digital QSL cards as well as a diploma if you have successfully scored enough points. Participating stations will provide an embedded log search in their QRZ page, and you can check how many points you have accumulated. The awards currently running are as follows:

    PZK-IARU

    This award is celebrating the 95th birthday of the PZK organisation and the 100th of the International Amateur Radio Union (IARU). The 1st round of the contest runs from the 17th Feb 2025 – 3rd Mar 2025.

    Stations worked today

    Pleased to have worked Martinique, Chile and Curacao for the first time, and QSL cards have been/will be requested.

    Map of today’s QSOs on 10m.

    Equipment and working conditions can be found HERE.

    Below is a graph of all contacts on 17/02/2025 by country count:

  • 9X2AW Dxpedition

    Today, 13th February 2025, I worked Harald 9X2AW during his Dxpedition to Rwanda. On 17m FT8, his signal in the North East of England was -19. His aim is to provide an opportunity for stations to get a new country in the log. He was very patient on the air as QSB meant we had to repeat our signal reports several times. However, after around three minutes, I got the final “73” and could breathe a sigh of relief. He is active until 15/Feb/2025 in Rwanda and QSL is via LoTW or direct paper QSL via M0OXO. You can view the OQRS service HERE to request a card (link opens in new tab).
