This is a MMDVM_HS_Dual_Hat hotspot in duplex mode with DMRGateway
and an actual Pi-Star image. In this setup I use DMR+_IPSC2-OE-DMO and
BM_Germany_2622 as master servers. I also use DAPNET and
I’m not the casual ham radio operator that always wanted to operate
his own ham radio station.
I tried CB once but had to travel quite a bit to
reach other stations (trucks on the highway for example). I’ve played with
SDR before and tried a few things with GNUradio and gqrx but I never got
deeper into this kind of things.
