Mini Node

The first mini-node has been sold out, a second generation is in development that will be available in Q2 of 2026. This version is similar in most aspects, but adds a wired ethernet connector and power supply, and incorporates modifications that were made to the earlier module. It uses the same power injector as before.

Power Node

Based on the new node development, the next generation node is planned for outdoor use and will include a power amplifier. It will consist of a four board stack, the ethernet adapter, Pi Zero and Radio node, plus a power amplifier.

It can be encased in PVC tubing to keep the cost down, using a 3D printed base to hold the board stack, and tubing which can be obtained from any hardware store. Any compatible antenna can be used, or a coaxial collinear can be fabricated from RG58 coax and is easy to build. A conceptual drawing of the node is below.

The amplifier will increase the power output to +37dBm, and the antenna gain will increase it yet again to +46, or approximately 50W EIRP. Based on the free space formula, this should give it a range of over 25 Km (16 mi).

Watch for future announcements on this site.

Supernode

The supernode will be the next generation of digital platform to breathe new life into aging repeater systems by marrying together analog systems that are Allstar based with up to three new digital modes, one that employs conventional TNCs for mobile or fixed data at enhanced speeds, the IP400 network mode, and a high speed OFDM based mode on 2.39GHz for linking an a secondary p-p network.

The design goals for the OFDM mode is to achieve speeds in excess of 1Mb/s, and distances of up to 30 KM (19 mi) as a minimum.
