Description
The Anytone AT-D878UVII Plus is a handheld portable radio for DMR digital radio (compatible with MOTOTRBO Tier 1 and 2), traditional FM is also supported. In contrast to many other DMR devices, the D878UV offers true VFO operation. Here, a radio operator can set a frequency and transmit parameters as usual, instead of accessing pre-programmed memory channels only. This makes this radio much more suitable for amateur radio than other DMR handhelds. Of course, the Anytone D878UV also comes with memory channels, 4000 to be precise. But you don’t just need to depend on pre-programmed channels. A further difference to other DMR devices is the possibility to change most (not all) parameters on the device. So you don’t have to rely on computer programming for every small change. However, the settings for really all parameters (e. g. the DMR ID) are only possible with a corresponding (free) PC software.
The AT-D878UV is the successor to the immensely popular D868UV. New with this radio is – among other things – the APRS function. The ‘878’ has more internal program memory which enables the manufacturer to incorporate more features in software. For example you can now set all APRS parameters through the menu, there is no need to reprogram the codeplug for such changes. And another new feature is ‘roaming’, i.e. the function where a repeater is selected automatically by checking the reachability of repeaters from a pre-defined repater list.
The further feature set of the AT-D878UVII PLus is very extensive. 4000 different channels can be stored (digital and analog, also mixed operation possible); 10000 talk groups are configurable and the memory holds up to 500,000 contacts. In analog operation, functions such as DTMF, CTCSS and DCS are supported, as well as coding with two-tone and five-tone signals. A tone burst of 1750 Hz is also available. Five buttons of the radio can be assigned individually with functions, so that each user can adjust this radio to his or her personal preferences. The 1.77″ large Colour display can be illuminated to different degrees of brightness and is easy to read even in the sunlight. To save power, the display is switched off after an adjustable period of time.
Another feature to highlight is the option to store multiple DMR IDs. So it would be conceivable to use the device both in a professional company radio environment, later on with another ID in the amateur radio band. Or several family members share one device. The Anytone AT-D878UVII Plus is equipped with a GPS receiver, the position data can be transmitted by radio. The AT-D878UV is a Dualband device for 2 m (VHF) and 70 cm (UHF), on both bands you can work analogue in FM or digital in DMR. In addition, a receiver is also available for the WFM broadcast band. The transmitting power can be set in 4 steps from a minimum of one to 6 watts (VHF) or 7 watts (UHF). The headphone/microphone jack is compatible with Kenwood or Wouxun. The antenna connection is a recessed SMA connector, so you can use Diamond’s optional antennas, for example those which end in “J” in the product designation. The programming cable is included in the scope of delivery, the programming software must be downloaded (for free) from the manufacturer.
