NOTE from Scott VA7SNJ regarding happenings at the Coffee Shack on September 8th.
“Rick, Roger and I tested harmonic attenuation of my newly-built QMX transceiver. Roger was his attenuators, Rick with his TinySA. Results good – 2nd harmonic 60 dB down from fundamental!”
On April 25th Scott Prior VA7LMP gave IslandHF a terrific presentation on Meshtastic.
Meshtastic is an open source, off-grid, decentralized, mesh network built to run on affordable, low-power devices.
It’s is a project that enables you to use inexpensive LoRa radios as a long range off-grid communication platform in areas without existing or reliable communications infrastructure. This project is 100% community driven and open source!
