DISCONTINUATION OF THE IRC ---> Since its introduction in 1907, the International Reply Coupon (IRC) has been a universal tool for sending international mail, used by people around the globe - including amateur radio operators, to cover the return postage of their coveted QSL cards. However, during the 28th Universal Postal Congress in Dubai (September 2025), member countries of the Universal Postal Union (UPU) voted to discon-
tinue the IRC, effective 31 December 2026.
The UPU describes this decision as "a natural progression within the broader transformation of international postal services, in alignment with the digital practices and modern outlook of their customers". Current 'Abidjan' IRCs already in circulation bearing the expiry date 31 December 2025 will now be valid for an additional year. It should be noted, however, that many countries have stopped selling or accepting IRCs for several years now.
RAEM CONTEST ---> This year's RAEM Contest (https://raem.srr.ru/) will be held on 28 December, from 00.00 UTC until 11.59 UTC, on 80, 40, 20, 15 and 10 metres CW. Organized by the Russian Amateur Radio Union (SRR), the annual event memorializes Ernst T. Krenkel (1903-1971), the legendary Arctic explorer and radioman (callsign RAEM) on various polar stations and on the first drifting ice station North Pole-1.
TZ4AM ---> "QRV on all bands 40m to 6m so far at high power", says Jeff. "Solar system is behaving nicely and power cuts occur less often, so I will be operating at higher power when called for. Mostly CW and some SSB". Operrations are expected to continue until February 2026. However, Mali is currently experiencing a severe, multifaceted crisis. If the situation deteriorates further, Jeff will evacuate.
YOTA CONTEST 2025 ---> The third session of this year's YOTA Contest, organized by the IARU R1 Youth Working Group in cooperation with the Hungarian Amateur Radio Society (MRASZ), will take place on 29 December (10:00-22:00 UTC) on the five classic bands CW and SSB. Everyone can work everyone. The complete rules can be found on https://yotacontest.mrasz.org.
