If you ever asked if you need an Unun or a Balun this article is for you. The right question should be do I need a feed line choke or an impedance transformer whose output is configured as balanced or as unbalanced. An impedance transformer can be configured as a voltage transformer or as a current transformer.

CATSync V1.30 integrates OpenWebRX support, expanding its capability to synchronize a local amateur radio transceiver's CAT control with a broader range of public WebSDR receivers. The software facilitates real-time frequency tracking, allowing the operator to adjust their physical rig's VFO and observe the connected WebSDR instantly follow the tuned frequency. This functionality is crucial for remote listening, signal comparison, and verifying propagation conditions across different geographic locations using a familiar hardware interface. The application supports both the classical WebSDR interface and KiwiSDR platforms, providing a consistent control experience across various online SDR deployments. It bridges the gap between local station operation and the vast network of globally distributed software-defined radios, offering a practical tool for DXers and contesters. CATSync is designed for Windows and Linux environments, with Android compatibility noted, making it accessible to a wide user base seeking to leverage WebSDR resources with their existing station setup.

The Barrow Amateur Radio Emergency Service Club (BARES) serves as a local hub for amateur radio operators in Barrow County, Georgia, focusing on community engagement and emergency preparedness. Established in 2007, the club provides a platform for hams to connect, share knowledge, and participate in various radio activities. Members often engage in public service events, offering communications support, and conduct regular meetings to discuss technical topics and operational procedures. BARES emphasizes the importance of emergency communications, with members frequently training for and participating in simulated emergency tests (SETs) and real-world disaster response scenarios. The club maintains a focus on local area coverage, ensuring reliable communication infrastructure is available when traditional systems fail. Their activities often involve operating on _VHF_ and _UHF_ bands for local nets and _HF_ for longer-distance emergency coordination. Key activities include field day operations, technical workshops, and supporting local events with radio communications.
