RETEVIS Launches High-Power Portable Repeater, Transforming Off-Grid Communication

RETEVIS derives from REdefine TElecommunications VIsion Signpost, a global leader in reliable two-way radio communication solutions, has unveiled its latest innovation: the portable repeater system designed to redefine longer range with reliability in off-grid environments. Combining industrial-grade durability with plug-and-play simplicity, this repeater aims to eliminate dead zones for family-guardian/outdoor, key-worker/business, and radio amateurs. Since RETEVIS RT97 became a popular portable repeater with its low-power version in 2018, RETEVIS has released the newly updated waterproof RETEVIS portable repeater - Retevis RT97L 25-Watt LCD High Power repeater.

ARRL Establishes Virtual NTS Traffic Net

To reach hams in areas not serviced by a National Traffic System (NTS) net on local repeaters, the ARRL has created the Virtual NTS Training Net (VNTN). Like a traditional traffic net, the virtual version will accept check-ins and radiograms over Zoom. VNTN currently meets on Wednesdays at 7:00 PM Eastern time.

Mesh Network for 70cm A Project in Canada

An ambitious project in Canada hopes to develop a mesh network to link repeaters and accommodate several digital modes. Hoping to combine the best features of such digital networks as HamWAN, AREDN and New Packet Radio, developers in Canada are starting development of a mesh network that will operate on the 70cm band.

“The first step is to get a simple chat and beaconing application running to experiment with the technology. From there we can layer on other features and frame types, and then consider moving into the repeater world.”

— Zero Retries, Martin Alcock, VE6VH

Writing in the newsletter, Zero Retries, Martin Alcock, VE6VH, said the project is being designed to link repeaters using RF and will include digital voice modes, data transfers, messaging and a data networking layer. The project is called IP400, short for Intelligent Protocol 400. It has the support of the Alberta Digital Radio Communications Society and is looking for contributors familiar with the C and C++ languages. Free open source code is being used for the development. IP400 is intended to operate on amateur frequencies between 420 and 450 MHz. Martin said that unlike conventional analogue links, a digital mesh platform will be capable of carrying compressed digital video as well as compressed audio and telemetry.
