DVmega CAST is a desktop unit with an integrated mini-computer and a chip for the AMBE + 2 ™ vocoder. This way you get a stand-alone device to participate in the D-Star, DMR and C4FM networks, without using a radio, without a big PC. This is very useful to remain reachable even beyond the range of a DV repeater's radio. Optionally, the DVmega CAST can be equipped with an HF module (VHF or VHF / UHF Dualband). This turns the network client into a complete digital voice hotspot.
IP RADIO DMR / D-STAR / C4FM MULTIMODE
The DVMEGA cast is based on a single Raspberry Pi Nano board computer. AME + 2 Vocoder is on its own card and is controlled by the computer, using the well-known "Pi-Star" Hotspot software. The network connection can be made via cable (Ethernet) or via WLAN. A touch display shows the operating status and allows control of the Pi-Star DV hotspot. An additional knob is provided for convenient and fast operation. Configuration is performed via the web interface of the Pi-Star software.
A microphone socket is available on the front panel. Here the developer has provided a Yaesu compatible mic connector, for example for MH-48A6J, where DTMF keys can also be used. Furthermore, a 3 W audio amplifier is integrated, the front speaker offers good fidelity of the decoded NF. Alternatively, you can also connect headphones.
A special feature of DVMEGA Cast is the ability to register the device with the developer. In addition to an e-mail address and the serial number of the device, no personal data is recorded. By registering the update procedure of the Pi-Star software used is much simpler, the operator receives the information in time, as soon as a new version is available. However, the operation is also possible without registration. In addition to version control, no other data is transmitted to the manufacturer.
Optionally, a DVMEGA Raspberry HF module, either the 70 cm mono-band module or the VHF / UHF dual-band module, can be integrated into the housing. Therefore, the "CAST" becomes a real hotspot through which, for example, it is possible to access the respective network - DMR, D-Star or C4FM with a portable radio. The housing already provides corresponding cutouts, a commercially available ribbon cable is required for installation. The DVMEGA Cast requires a supply voltage of 12 V, approx. 1A per operation. A power supply is not included in the supply.
