From the folks that brought us the ircDDB network, we hear from Hans-Jürgen Barthen, DL5DI, that there is now a gateway between D-STAR (DCS Gateways) and Hytera DMR Repeaters using the AMBEServer with either the DV3000 or ThumbDV™. This gateway is in use at a handful of DMR repeaters in Germany and Austria with systems soon to be implemented in Sweden and Switzerland. You can download executables for the gateway and combine with the AMBEServer to create your own gateway. The software does D-STAR callsign to DMR radio ID mapping and transports audio between networks using the Hytera API.

Although not light in weight, the solid construction becomes an advantage when erection is required off a vehicle on a hard surface, when picketing and guying is not possible.

Al meer dan 5 jaar geleden heb ik al eens een paar goedkope traps gemaakt en er een klein stukje over op mijn website gezet, met de ontwikkelingen dat de Novice amateurs (binnenkort) op HF mogen leek het me eens een leuk idee om het netjes uit te werken.
