KP4IP Portable Digital Gateway (MMDVM)

7/19/2018 – This is one of my latest projects made in about an hour. Its is a Digital gateway made with a MMDVM V1.6 modem transceiver, using the Pi-Star software wrote by Andy Taylor (MW0MWZ) I can access multiple digital modes like ( DMR, D-Star, YSF/FCS, P25 and NXDN ) with a single gateway and the internet. 

 

The gateway was made thinking about interoperability, it can be utilized with a voltage range between 9 to 32 VDC or with a micro USB 5V power adapter.
