Advancing Digital Radio

   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 here:

  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.    73, K8YPH, Tom
