Bulletins

No Changes to Multipliers in 2025 ARRL November Sweepstakes
In response to the Radio Amateurs of Canada's recent addition of a new Yukon section, the ARRL Contest Advisory Committee is reviewing Canadian Section multipliers for ARRL contests that use Sections as multipliers. While this review is ongoing, the 2024 multiplier list will be used for all Section-based contests for the remainder of 2025. Stations located in Yukon should continue to send "TER" (territories) for the 2025 ARRL November Sweepstakes CW/SSB and ARRL 160-Meter contests.

WRTC 2026 Email Reflector
The World Radiosport Team Championship (WRTC) 2026 committee would like to remind anyone interested in the event (which will be held next July in parallel with the IARU HF World Championship), to subscribe to their email reflector to keep informed of the latest event news.

Technical Topics and Discussion

SkyRoof Version 1.20 Beta Now Available
Alex Shovkoplyas', VE3NEA, latest version of SkyRoof software, which integrates both a software defined receiver (SDR) interface and amateur satellite tracking, is available at ve3nea.github.io/SkyRoof/index.html [ https://ve3nea.github.io/SkyRoof/index.html ] . The program provides detailed information about all amateur satellites, real-time tracking, and pass prediction. The program will work without an SDR or transceiver, but not all functions of the program will be available.
