Regular uploading of your log during the month is encouraged – registration and at least one upload must be made by 15 March and once per week is preferred – as this helps to drive the Challenge and provides a spectator sport for all to see.

LF Challenge 2025 Results
The 2025 LF Challenge was well supported again this year with 75 members taking part. During the month there was plenty of DX to chase with DXpeditions from VU4AX, VK9XU, VK9CU plus various other DX including Antarctica, Galapagos Islands, East Kiribati and Rodriguez Island.
This year a total of 18,768 QSOs were made with 191 DXCCs recorded. MGM modes made up 46% of the QSOs with 31% CW and 23% SSB.

Lionel, G5LP once again topped the CW table in this year with 76 DXCC worked, but having won the trophy last year is not eligible under the 3 year rule. So the PENALLT TROPHY for 2025 goes to Paul, MM0ZBH who came second with 64 DXCC. Audrey, 5B4AMX was third with 53 DXCC.
The TINDLE CUP for most DXCC worked using SSB this year also saw the 3 year rule apply. John, GM0OPS was the overall winner with 76 DXCC but having won the trophy in 2024 means this year it goes to William, N6RV who finished in second place with 64 DXCC. Stephen G7BXU came in a close third with 63 DXCC.
The CLUBLOG TROPHY for the MGM section was won by Norman, 5B4AIF with 141 DXCC worked and second place goes to Chris, G4FZN with 122 and third place was Audrey, 5B4AMX with 100 DXCC.
A very close 160m section this year saw Andrew, M0NKR as the overall winner with 51 DXCC and just two behind in second place was Andrew, G8GNI who worked 49 DXCC. Third was Audrey, 5B4AMX with 47.
The 80m section this year was won by Audrey, 5B4AMX with 78 DXCC; John, GM0OPS was second with 76 DXCC and in third place was Norman, 5B4AIF with 73 DXCC.
This year’s 40m section winner was Norman, 5B4AIF with 142 DXCC. Second place goes to Chris, G4FZN with 121 DXCC and in third place was Lionel, G5LP who worked 113 DXCC.

LF Challenge 2024 Results
This year’s LF Challenge again saw a decline in the number of DXCCs worked pretty much across all sections apart from Phone which was up four on the 2023 LF Challenge. Solar conditions affecting the lower bands would be one of the reasons for this, that said this year was still well supported with 75 of our members taking part and working plenty of DX, including FW, H40, KH2, KH0 plus many more.
The PENALLT TROPHY for most DXCC using CW was won by Lionel, G5LP with 76 DXCC, followed by Paul, G4PVM with 69 DXCC and third place goes to Chris, G4FJW with 57 DXCC.
The TINDLE CUP for most DXCC using Phone was won this year by John, GM0OPS with 80 DXCC and in close second place was William, N6RV with 78 DXCC and Norman, 5B4AIF was third with 73 DXCC.
The CLUB LOG TROPHY for most DXCC using MGM goes to Brian, G3VGZ with 133 DXCC. Just one behind was Norman, 5B4AIF with 132 DXCC and again only one behind was Andrew, G8GNI with 131 DXCC. It was extremely close at the top!
The 160M section this year saw joint winners, Norman, 5B4AIF and Brian, G3VGZ both on 49 DXCC, in second was Stewart, G3YSX with 35 and third Tim, M0BEW with 22.
The 80M section goes to Brian, G3VGZ who worked 76 DXCC and joint second was Norman, 5B4AIF and Lionel, G5LP with 73 DXCC and third John, GM0OPS with 66 DXCC.
The 40m section was won by Norman, 5B4AIF with 142 DXCC. Brian, G3VGZ was second with 130 and Andrew, G8GNI was third with 128 DXCC.

A total of 22,223 QSOs were made during the LF Challenge, 9991 of them was using MGM, 5776 on CW and 6456 on SSB.

Although MGM came out with the higher percentage of QSOs, the above chart interestingly shows it was not quite the dominant mode on the LF Challenge as it was in the HF Challenge from September last year.
Many Congratulations to all the winners, some really close scores in a couple of the sections which kept the competition very much alive to the final day. The LF Challenge really does require commitment with late nights, early mornings and even sleepless nights!
Many thanks to Michael, G7VJR as always for allowing us to run our awards programme on Club Log.

Also the change in the solar cycles would have an adverse affect on the conditions for the lower frequencies.
Congratulations to all winners. Thanks to all who rose to the challenge even with the difficult conditions and sleepless nights.

CDXC LF Challenge 2022 Results
The Penallt Trophy and Salver for Traditional SSB/CW modes in 2022 is awarded to John GM0OPS.
The Tindle Cup and Salver for MGM modes in for 2022 is awarded to Gordon G3PXT
The 2022 largest number of DXCC’s of 155 was achieved by Savvas SV2AEL in MGM modes but Is not eligible for a Trophy as he has won this in the past three years.
The number of DXCC’s during the 2022 LF Challenge was lower than the previous years but still well supported by members. As expected in these changing times the traditional modes were particularly reduced. The lifting of COVID restrictions in 2022 returned freedoms of movement which has affected the results as many members returned to work. Also the point in the solar cycle has an adverse effect on the conditions for LF.
As defined in the rules “All logs must be uploaded by 23:59 on 5th April”. Any upload after that date is not taken into account when deciding the results.
Congratulations to all winners. Thanks to all who rose to the challenge even with the difficult conditions and sleepless nights.
