At the 2016 Dayton Hamvention this week, we got to see the DV4mobile – the upcoming tri-band, all-mode digital radio that was announced by Wireless Holdings, maker of the DV4mini digital adapter. The radio was on display at the Wireless Holdings booth and we got to talk with Kurt, OE1KBC and Torsten, DG1HT to learn more about this impressive little mobile.

To recap, the radio will operate on the 2m (144 – 148 MHz), 1.25m (222 – 225 MHz) and 70cm (430 – 450 MHz) bands and will initially supporting DMR, D-STAR and C4FM (System Fusion) digital voice modes when it is released in Q4 2016. With subsequent software updates 2017, the radio will also support P25, dPMR, NXDN and NEXEDGE. Since the radio is essentially a Software Defined Radio (SDR), it can easily be programmed to support any new digital voice modes that hams might want to use.

The idea creating a multi-band, all-mode digital mobile radio was initially conceived by Kurt and Torsen in early 2015 and the first prototypes of the radio were received in March 2016. Both Kurt, who is the administrator for the DMR+ network in Austria and Torsen, an Assistance Professor in the area of Artificial Intelligence at the University of Hamburg in Germany, collaborated on the initial design of the radio, known then as “NEW RADIO”, however it was Wireless Holdings that took the step of having the radio manufactured and ultimately made available to the ham community. DV4mobile is the brainchild of this combined effort and will undoubtedly become the next big “must have” radio for digitally driven operators within the ham radio community.

Of the many impressive features proposed for the DV4mobile, one of the more intriguing features of this radio is its support for LTE. Coined as “DV4LTE”, it will enable the radio to operate as a network connected device anywhere in the world using the T-Mobile global LTE network. With the help of DV4LTE, the DV4mobile will be able to support:

  • the ability to download repeater information for DMR and DMR+ repeaters worldwide based upon the GPS location of the radio
  • remote programming capability via a web interface where all configuration changes or software updates will be pushed to the radio from the cloud via LTE. It will also support similar functionality using WiFi (2.4 and 5.0 GHz) or via Ethernet via the RJ-45 connector should an LTE network not be available
  • Remote control operation using an iPhone and Android app (also supported by Bluetooth and WiFi for local operation)
  • SMS, both sending and receiving
  • the ability to send and receive Facebook Messenger messages and Twitter tweets
  • EchoLink operation using FM operation

When users purchase the radio, it will include DV4LTE service for one year. Pricing for DV4LTE service thereafter was still being worked on by Wireless Holdings, however they felt that it would be a very affordable price that most hams would find quite reasonable. Also, users will not need to purchase a SIM card to use DV4LTE, as the LTE card inside of the DV4mobile will employ a virtual SIM card.
