The Salvation Army Team Emergency Radio Network (SATERN) is a vital resource for amateur radio operators involved in emergency communications. This network facilitates the coordination of communication during disasters, ensuring that vital information can be relayed effectively. SATERN operates through a series of nets that connect operators across various regions, allowing for real-time updates and support during emergencies. Participation in SATERN not only enhances your skills as an amateur radio operator but also contributes to community resilience. Operators are trained to handle emergency traffic and provide assistance to those in need. By joining SATERN, you become part of a dedicated team that prioritizes safety and communication in times of crisis. The network encourages regular participation in drills and training sessions to ensure readiness when real emergencies arise.

The Covey Hill Amateur Radio Club operates a 146.685 MHz analog repeater with an 88.5 Hz PL tone, alongside several digital repeaters. The resource details specific frequencies and modes for D-STAR (145.590 MHz, 1266.300 MHz voice, 1297.675 MHz data on 23 cm), DMR-Marc (448.525 MHz), DMR-Brandmeister (441.750 MHz), Yaesu Fusion (449.725 MHz), and P-25 Digital (147.315 MHz). It also lists Echolink node 595040 (VE2REX-R) as an access point for the club's network. A recent update, dated June 19, 2024, announces the VE2REX analog repeater and Echolink are fully functional again, after resolving issues including a conflicting 100.0 Hz tone, software repairs for Allstar and Echolink, a suspected defective USB port on the Mini PC, and a faulty exciter in the Motorola Quantar repeater. Guy, VE2VMT, was instrumental in troubleshooting these problems. The club, established in 1994, provides a calendar, news, links, and membership information, with Linda Cullen, VE2NJK, serving as president and VA2DBJ as webmaster.

This is a very small vertical 160m antenna that fits in the loft of even my small house. It was built as a way of getting a signal out on 160m for local AM contacts, but the local noise level was far too high to allow it to be used at night for this purpose. However, on WSPR it did a pretty good job with WSPR spots from a very long way across Europe being received when running 2.5W out.
