Ham Radio Transceivers

Anytone AT-778UV FM Dual Band Transceiver

The Anytone AT-778UV is a popular dual-band FM transceiver known for its affordability and solid features. Operating on VHF (144-148 MHz) and UHF (440-450 MHz) bands, it offers selectable power outputs of 25W, 15W, or 5W. Its bright 180-degree TFT LCD display and intuitive interface enhance usability in various settings. While it delivers good audio quality and a robust build, it lacks a dedicated volume knob and may heat up during extended use. Overall, it's an excellent entry-level choice for amateur radio enthusiasts.

Top Amateur Radio Websites – Issue 2637

This week, we're looking at some interesting developments in the LoRa space, particularly how it's being leveraged for amateur radio applications. We've got a few resources that touch on mesh networking, off-grid text messaging, and the integration of LoRa with APRS. For those experimenting with portable setups or considering resilient communication methods beyond traditional HF, these items offer practical insights. There's also a utility for managing virtual serial ports, something that comes up often when interfacing modern transceivers or microcontrollers with logging software or control applications. It’s a mix of hardware-adjacent firmware projects and mapping tools, all relevant for operators keen on digital modes and self-contained systems.
