ARDC Launches 44Net Connect

ARDC has launched 44Net Connect, a new portal designed to make it easier for ham radio operators to gain access to and experiment with subnets of the 44.0.0.0/8 IP address space. Through the portal, hams can apply for VPN access to 44Net, which comes with a dedicated 44Net IP address. Tunnel services are provided through WireGuard with options to add IP networks and autonomous system numbers. Proof of a ham radio license is required.

International Reply Coupons (IRCs) to End

Although International Reply Coupons, or IRCs, are still being used by some DX-chasing hams in their requests for QSL cards, that option is set to end by this time next year. Countries belonging to the Universal Postal Union have voted to discontinue their use effective 31 December 2026. The vote was taken in September at the 28th Universal Postal Congress held in Dubai. There are a number of IRCs already in circulation that bear the expiration date of 31 December 2025, and they are expected to be honoured for another year.

In an era marked by a migration toward confirmations on digital platforms and in digital QSOs, the move brings an already disappearing amateur radio practice to its conclusion. A statement from the Universal Postal Union said the sunset of the IRC, first put into practice in 1907, was “a natural progression within the broader transformation of international postal services in alignment with the digital practices and modern outlook of their customers.”

New Satellite Tracking Application Released

Bob McGwier, N4HY, has announced the release of a new satellite tracking application entitled Visible Ephemeris.

Visible Ephemeris is a modern, spiritual successor to Quiktrak (1986), re-engineered for the Raspberry Pi 5 and modern silicon. It is capable of propagating 13,000+ satellites in real-time with sub-second updates while maintaining <5% CPU utilisation. Visible Ephemeris is high performance physics-based program using Kelso/Villado SGP4 to track satellites (all in the Celestrak TLE). It uses McGwier’s implementation of Pedro Escobal AOS/LOS search, but rewritten for altitude and not Eccentric Anomaly. The code is designed for and intended for the Raspberry Pi and displays graphics components using Web UI.

It features a Hybrid Decoupled Architecture where the UI, Orbital Mechanics, and Network Services run on independent threads, ensuring the interface never freezes—even during heavy calculation loads.

Visible Ephemeris has been released under the MIT license and further details can be found at https://github.com/n4hy/VisibleEphemerisCPP.git
