Sparkfun now has a dedicated APRS transmitter!


"

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 APRS <http://www.aprs.org>.

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.

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.

*Note:* 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.
