So according to this award I spent 180+ days hunting WWFF activations... should I be worried? 😁 😅

See what you were up to last year at: https://wwff.co/wwff-marathon-2025-awards/

OpenHamClock (https://openhamclock.com) tracking grayline conditions for KP5/NP3VI Desecheo Island DXpedition.

Finally heard KP5/NP3VI Desecheo Island DXpedition at my station OG7J via grayline propagation on 10m SSB. Had to wait for the right time for a QSO: they use very low TX power (20-30W?).

Running https://webradiocontrol.tech/ for remote and https://openhamclock.com/ to track conditions (an excellent, modern "spin-off" of HamClock).

After maybe a year of procrastination 😅, I finally installed a dew heater in my #allsky camera -> ice and snow are finally gone and the photos are super clear. 👌

Now waiting for aurora!

The heater is from dewcontrol.com, driven by a #RaspberryPi GPIO + an opto-isolated relay. The indi-allsky software cleverly tracks dew point using I²C environmental sensor readings.

The exact heater model is this one: https://www.dewcontrol.com/product/dew-heater-module---all-sky-camera

New year, new laptop! The #HP #ZBook Ultra G1a, based on AMD Strix Halo line of Ryzen AI CPUs, really shines with its 200+ GB/s memory bandwidth - where the Intel Core Ultra 9 mobile CPUs (2ch) only do ~100 GB/s. 128GB of quad-channel LPDDR5x-8533 FTW!

Also, I really like the new Linux Mint 22.3: the Cinnamon desktop looks great and hardware support for this particular ZBook is perfect!

Happy new year 2️⃣ 0️⃣ 2️⃣ 6️⃣ 🎆 ! This year, Web Radio Control remote control software will get some long-awaited updates: a redesigned web user interface (screenshots to follow soon), software update mechanism and plenty of improvements to make setup easier than ever.

We're also working on some significant new features on #Hamlib software with @OH3CUF - check out the @ARDC -funded project plan in GitHub: https://github.com/orgs/Hamlib/projects/1

The yearly cost of radio amateur license in Finland is going to almost double beginning of 2026.

The Finnish Transport and Communications Agency #Traficom increases their basic frequency fee and due to this radio amateur license will cost 35€ per year instead of old 18€ per year.

This cost increase is for every callsign in use so especially clubs running multiple repeaters, APRS and other automatic sites will take a big hit on their budget.

Traficom service fees to increase from 1 January 2026 | Traficom

Service fees charged by the Finnish Transport and Communications Agency Traficom will increase as of 1 January 2026. The increases will apply, for example, to consumer service fees and supervision fees charged to organisations. Fee increases will mainly range from approximately 10 to 20 per cent. Prices will increase in the areas of aviation, maritime, road and rail transport, as well as for domain name and frequency fees.
