<p>The HX1 is a low-power amateur radio transmitter set
to a fixed frequency of 144.390 MHz. In North America, this frequency is
used for the Automatic Packet Reporting System, or <a href="http://www.aprs.org">APRS</a>.</p>
<p>APRS is a standard used by amateur-radio operators to broadcast live
sensor data on a shared frequency. This data can be received by anyone
with the proper equipment, and is aggregated on the internet through
gateways run by members of the APRS community. APRS is commonly used to
share real-time data including vehicle location (GPS), weather stations,
high-altitude balloon tracking, remote sensor platforms, disaster
relief coordination, and more. It’s effectively an open-source,
open-data, community-run, free to use, IoT system with potentially
worldwide coverage.</p>
<p>The HX1 is a 5V, low-power (300mW), narrowband (3kHz) VHF FM
transmitter module. With a simple antenna, the range will be around 6
miles. Since this is a “bare” transmitter, the data input must be
properly modulated and formatted. There are several Arduino software
packages that can do this, see the hookup guide for information.</p>
<p><strong>Note:</strong> Because it uses amateur radio frequencies, you
will need an amateur radio license to use the HX1. It’s easy (and fun!)
to get one.</p> </div>
