LoRa APRS has taken off in a big way around here over the last year. And I have made several videos on the topic already. As @richonguzman has just released version 3.0 of his excellent iGate / digipeater firmware I had to take a look. The biggest news in this release is the "Ultra Low Power" mode for battery operated digipeaters. So join me as I install and configures this latest version of the firmware and put the low power mode to the test with the "Power Profiler Kit II" from Nordic Semiconductors.
