https://www.youtube.com/watch?v=k8NUZQ8LOsgThe DV4mobile is another member of the successful family of DV4 products.
It operates in the 2 meter band, at 222 MHz and the 70cm band.
All modes are supported: C4FM, D-Star, DMRplus, dPMR, P25 (NXDN later via software update) Voice over LTE and of course, FM!
C4FM both narrow and wide band modes
D-Star (DCS,CCS,REF,XRF,XLX)
DMRplus (TS1 all / TS2 Reflectors or talkgroups)
dPMR(All Systems and codecs transparent mode)
P25(Phase 1 Only and all NAC transparent mode)
FM with PL and DCS tones and RDS for call sign transmission in the background
DV4LTE is a new voice over LTE mode that connects the radio to the reflector using an LTE connection.
The LTE modem connects to the CCS7 reflector system supplying codeplugs in the cloud, there is no need to program codeplugs any more. Any changes in the network, be it on the reflector, repeater or user side are instantly updated. Private settings such as local channels can be maintained on the web.
After a reset or with a new radio all settings are downloaded after entry of the CCS7 number.
When no repeaters are in range, the radio can revert to LTE (DV4LTE) for reflector connection (i.e. between metropolitan areas)
The GPS module provides location data for APRS and automatic display of repeaters in range. When a repeater is selected, frequency and mode is already in the radio, no programming!
Simplex repeater mode
The DV4mobile can also be used as a dual band, dual mode simplex repeater.
For example you can use it as a D-Star repeater on 2m and simultaneously as a DMR repeater on 70cm while conducting FM QSO on 222 MHz (USA version only)
The extreme temperature range from -40C to +85C ensures functionality even under the most extreme conditions
