DV4home V2
The DV4home V2 is another member of the successful family of DV4 products. As usual it supports all digital modes, while simplifying and extending the supported functions. While it acts as a “home” for the DV4mini it can be easily used mobile or portable as well. It is a stand-alone unit that does not need a PC to operate. (DV4mini not included)
(Automatic updates of firmware via Internet)
DV4home V2
The DV4home V2 has 2 AMBE3000 chips, a microphone connector to the unit. There is a built-in speaker and the microphone is included.
These components allow these additional functions:
- Direct Internet transceive mode without a DV4mini by using the microphone and the speaker. This is an economical alternative if no local wireless signal is needed. In this mode the DV4home supports D-Star, DMR, NXDN, and C4FM.
- Dual mode support: even without a DV4mini inserted the unit can be simultaneously connected to a D-Star and a DMR reflector, using 2 separate speakers to play the respective audio streams.
- Conference mode requires a DV4mini inserted into the unit and allows to use the built-in microphone/speaker connectors and the RF connection through the DV4mini to a DMR or D-Star radio. This mode works in D-Star and DMR.
- DMR/D-Star Bridge mode allows to interconnect DMR and D-Star reflector rooms using the licensed DVSI AMBE chips. This mode bears the risk of creating loops in the network, therefore a free license key is required which also helps that the installations can be supported by the network administrators to assure a flawless integration.
