DV4mini Hotspot for the 70 cm band and can use it with a D-STAR or DMR or C4FM * transceivers – The DV4mini is a very small but also very capable USB Stick that can expand any PC into a Hotspot for the D-STAR and DMR modes (C4FM * Fusion is in development) – (trial beta ver. 18.8 or later uncheck “C4FM Gateway” only DN & VW mode) – Please read official data and the User manual! (link below)

DV4mini allows linking with DCS, XRF and REF refectors for D-STAR as well s DMR refectors (trial beta ver. 18.8 or later unckeck C4FM Gateway!). With the DV4mini it has become possible to create a hotspot with minimal resources and thus get access to the (Digital Voice) DV network.[Note] Refector is a server connected to the Internet or Ham Net and is linked to a number of digital Ham Radio repeaters. If one of these repeaters is active it will send the voice data stream to the refector- (Xrefectors are the second generation of D-STAR reflectors… etc) – (DCS (Digital Call Server) is the most modern D-STAR refector system and in worldwide use, each as 26 rooms) – (DMR refectors consist of several regional servers, ach other via a superordinate network one Hytera & one Motorola) (System Fusion supports WIRES-X internet linking – .. node station requires external optional HRI-200 !)

The DV4mini is a great UHF digital hotspot. It’s support D-Star, DMR and C4FM* !! Very promising technology in process.
The DV4mini will be connected thru the USB interface with a PC or a single board computer (es: Raspberry PI 2 Mod. B also a keyboard, mouse and HDMI display) and the required software will be installed: V.1.4 DV4mini Controll Panel.
Frequency 420-450MHz – Modulation types: D-Star GMSK (Gaussian 2FSK) – DMR PLUS 4FSK Raised Cosine – C4FM Fusion DN & VW 4FSK, in process* – Power output: 0.03 mW to 10 mW. – RX -120dBm – Read more to the official web-page.

I believe not now, it’s available for Windows, Linux and Raspian ! (Raspberry Pi 2) – For those interested in digital communications, like D-Star, DMR and C4FM there’s a new dongle who will be coming out soon (… they are saying it will be available for international shipping next week).

    Yes we did talk. Once I got 1.64 correctly downloaded and installed I have had no further problems. It seems that while downloading the file windows wants to make it in HTML file, there in lies the problem. Had to manually change it to the correct extension then everything worked fine after that. I hope that you're really enjoying your DV4mini and are making lots of contacts with it. I know I have really enjoyed mine and have showed it off at our Saturday morning coffee twice. Our group started out with 4 Hams at coffee on a Saturday morning and now we have 15 to 20+ attending. Out of this group was born the "Bakersfield Digital Repeater Group". Time to start getting ready for this.


Thanks for your comments, Comments may take a day to show up
