It is available on Google Play - free of charge, no ads. Enjoy! C8K: POSTPONED ---> The original plan was for the C8K DXpedition to Mozam- bique, organised by the Czech DXpedition Group (https://www.cdxp.cz), to take place in January-February 2025. However, it was postponed for the first time to January-February 2026 due to safety concerns [425DXN 1757]. Now, due to overlapping work and personal schedules within the team, it has been rescheduled again, this time to September-October 2026. "This adjust- ment allows the full intended team lineup to participate and helps ensure safe, well-coordinated logistics and the best possible on-air performance", they say. Further information is expected in due course. CONTEST UNIVERSITY 2026 ---> Registration is now open for the 2026 Contest University (CTU), to be held on 14 May at the Hope Hotel in Dayton, Ohio. This is the day before the Dayton Hamvention officially opens. See https://www.contestuniversity.com/ for the details.

S21DX: POSTPONED ---> The DXpedition to Kutubdia Island scheduled for 21-27 December has been postponed to a later date in 2026. This decision was made after careful consideration of several factors, including logistical and op- erational challenges in the region, as well as concerns about adequate re- source availability. The new activation dates will be announced once all necessary arrangements and resources have been confirmed. VP0SG ---> Amateur Radio DXpeditions (ARD) has reached a key milestone in preparing for the March 2027 VP0SG South Georgia DXpedition [425DXN 1777] by signing the vessel contract for the MV "Meredian". This ice-strengthened vessel is ideal for the sub-Antarctic environment and is operated by 60 South Expeditions, who have significant experience in the region. Progress with the Government of South Georgia & the South Sandwich Islands is positive, as they are open to collaborating on plans while the formal permit process will begin in 2026. The operator team is forming, with twelve confirmed operators already and the possibility of two more. Fundraising is now fully underway, inviting support from foundations, clubs and individuals for this unique expedition: https://www.ardxpeditions.com/dxpeditions/vp0sg. USA: 60 METRES---> The Federal Communications Commission (FCC) has allocated 5351.5-5366.5 kHz to the amateur service on a secondary basis, with a per- mitted power of 9.15 watts ERP. The FCC also has authorized US amateurs to continue using four existing channels (centered on 5332, 5348, 5373 and 5405 kHz) on a secondary basis, with a permitted power of 100 watts ERP. The 60- meter allocation is available to amateurs holding a General Class or above license. The maximum permissible signal bandwidth is 2.8 kHz. The new rules will go into effect 30 days after publication in the Federal Register. [Source: ARRL] + SILENT KEY + Bob Whelan, G3PJT passed away on 4 December.
