**** De door Hamshop aangeboden Hytera apparatuur is bestemd voor de radiozendamateur (hobbyist). De firmware (besturing) is door deze groep hobbyisten zelf geschreven en is kosteloos. Er is voor deze groep geen service ondersteuning. Voor de professionele markt wordt er vaak firmware en software op maat gemaakt en is er professionele service ondersteuning. Hier gelden dan ook andere prijzen voor! Bel of mail ons indien u bedrijfsmatig een digitaal communicatie netwerk wilt opbouwen. ****

Dual mode and automatic change
The RD985 repeater can be operated both in analogue and in digital mode and is completely compatible to the currently used analogue systems. The device can automatically change between digital and analogue mode depending on the type of receiver signal, and thanks to the elimination of manually configuring frequencies and channels both time and money are saved.

100% efficiency
The RD985 offers a constant power (up to 50 watt) and in this way meets the high requirements of all conventional digital radio systems.

Flexible installation options
The repeater RD985 can be installed in a 19-inch equipment rack with an optional installation kit. Alternatively, you can easily install it on a rack, a mounting support or a work table. Thanks to the space intended for an optional duplexer inside the device, the device remains compact.

Efficiency in the high-frequency range
Thanks to the applied TDMA technology, twice as many users can use the same channel as in case of analogue or digital FDMA systems. Due to the restricted frequency resources, this represents an important relief and reduces the expenses for system terminals and frequency licences.

Secure communications
The RD985 repeater includes an expanded digital encryption function which protects your communication against wire tapping

High cooling capacity
Thanks to the heat dissipation the power amplifier can dissipate its heat extraordinarily efficiently. In addition, the integrated fan system supports the stable and efficient operation.

Operation in repeater and/or basic mode
If the repeater is operated on an analogue channel, you can select between repeater mode and basic mode. In basic mode the repeater can be used as a duplex transceiver.

High reliability
Since the repeater was designed according to military standards, it offers high reliability and excellent performance. The test results of independent laboratories showed that the trouble-free service life of the device amounts to up to 100,000 hours, thus meeting the requirements of use in extreme situations.
