and at about 2/3 Jaycar prices too.</p>
<p>I believe that 915Mhz is recommended in Aus.</p>

Not quite sure why we're talking about LoRa in the Australian <b>APRS</b> list,
but anyway...

<div>... and probably something similar available from Jaycar,
I guess?</div>

<div>We've been using LoRa modules in the Project Horus
'flight termination' payload (which also has GPS tracking)
for a few years now. We run them on the 434 MHz ISM band at
25mW, for command & control of the cutdown mechanism
(nichrome wire). We have a whole ecosystem of software based
around communicating with the cutdown payload and
transferring data around the chase car's network.</div>

<div>Quite a few libraries around to talk to the LoRa ICs
(usually a Semtech SX127x series chip). </div>

<div>Unfortunately the LoRa modulation scheme is patented, so
use of it on the amateur radio band is a bit contentious. At
the very least, there's a reverse engineered gnuradio library
available: <a
