Hytera repeater network is NOT part of DMR-MARC

The Hytera repeater network is NOT part of DMR-MARC, nor will it ever be. That is an independent DMR network with an incompatible IPSC platform. MotoTRBO repeaters are required for all DMR-MARC affiliates.

Digital Voice Standards - MicroHAMS Digital Conference 2015

John Hays from Northwest Digital Radio, does a great job of comparing the major digital voice options we have for Amateur Radio. He covers D-Star, DMR, System Fusion from Yaesu and the only Open Source option: FreeDV. The first three all use the same AMBE vocoder so these systems have a lot in common. Even so, they are not too compatible.

But John has a treat for us. He has developed a controller board that will all the Yaesu DR-1X System Fusion Repeater to upgrade from Dual-Mode to Tri-Mode and run D-Star, System Fusion and traditional Analog FM all in one box. Scrub ahead to 42:16 if you want to dive right into this part of his talk.

DV4mini news (D-STAR and DMR HotSpot)

DV4mini news (D-STAR and DMR HotSpot):

Advance Notice

NEW! Production has started, price and lead time will be announced after

HAM RADIO fair. NEW!

One of the first (or even the first?) D-Star and DMR Hotspots worldwide!

Reservations: If you want to be part of the first production run you can reserve a DV4mini (not binding).
Just send us a note using the contact form of the shop.
We will then reserve the quantity and you will be notified at your email address as soon as an official order can be made.

DV4mini is a tiny but powerful USB stick that can change any PC into a HOTSPOT for the modes D-Star and DMR (C4FM Fusion is being prepared).
It contains a powerful 32-bit micro controller as well as a complete 70cm transceiver and modulator/demodulator for GMSK and 4FSK (including raised cosine) as well as a USB interface.
It does not require its own power supply as it is powered through the USB interface.
Thanks to a power saving voltage transformer even older USB interfaces will suffice.
It will be shipped with a comprehensive but simple to use software package which allows for the linking with DCS reflectors for both D-Star and DMR reflectors.

For Digital Voice enthusiasts: your handheld radio is no longer gathering dust.
This hotspot brings the D-Star or DMR reflector directly into your shack.

For DV Power Users: It is possible to plug several of these sticks into a PC, thus allowing simultaneous operation with several reflectors (even D-Star and DMR mixed).
Well if you so desire you can fully use all your USB sockets with DV4minis and create a DV Center that way.

For home brewers: the DV4mini runs well on single board computers e.g. Raspberry, BananaPi, Odroid etc.
The minimum requirement is a Dual-Core. Such a hotspot would only need a few Watts and be useable in continuous service.
