Digital radio is available in many forms for amateur radio operators. This website
deals mainly with digital voice over the internet, using a hotspot, openspot, jumbospot
or other multi-mode digital voice modem (mmdvm). The mmdvm with built in uhf/vhf
transceiver receives the digital radio signal from your digital handheld and sends
it over the internet to a reflector, a digital voice server where it is shared by
others who connect to the same server.
The Raspberry Pi miniature computer (photo right) with open source software such
as pi-star has made it all possible. Pi-star has been developed by Andy Taylor (MW0MWZ)
and his team of contributors and is constantly updated and improved.
To quote the author Andy Taylor, “Pi-Star can be what ever you want it to be,
from a simple single mode hotspot running simplex providing you with access to the
increasing number of Digital Voice networks, up to a public duplex multimode repeater!
The world is at your fingertips, and the choices are yours!”Pi-Star can be downloaded
Pi-star supports D-Star, DMR, C4FM, P25, NXDN, and DMR+.
It is the purpose of this website to assist you in getting off to a good start with
tutorials and resources to find the right equipment. Most of all, try something
new and enjoy amateur radio with a twist. A great alternative for those that live
in restricted zones, and are no longer able to maintain traditional antenna systems.
