Alinco RS-D7

Alinco Inc. released digital repeaters ALINCO RS-D7. They are designed to work in Analog and Digital radio networks. They provide the construction of digital radio communication networks of the DMR TierII and TierIII standard and are compatible with other well-known brands.

RS-D7 repeater is designed to organize communication between subscribers working in a dual-frequency simplex. IP-connection allows relays in different areas to transmit data, voice and packets over a TCP / IP network.

The repeater can be used as a radio extender both when operating at the same frequency, and when receiving and transmitting is carried out at any different frequencies within the operating range of the repeater (136-174 MHz).

Alinco RS-D7 digital repeaters, like analogue ones, are designed to increase the coverage area of ​​the radio signal of subscriber and base radio stations. But digital repeaters have several advantages over analog. A significant advantage of this Alinco RS-D7 repeater is the ability to program it both using a computer and manually, which is not of little importance if you need to quickly change some parameters of the repeater, for example, frequency. In the price / quality ratio, the repeater surpasses its counterparts.

The Alinco RS-D7 repeater works according to the following principle: at the same time it receives a signal on one radio frequency, amplifies it and transfers it to another. Thus, the Alinco RS D7 repeater works both as a transmitter and as a receiver.

Subscriber radio stations for working with a repeater are programmed in half-duplex mode, also called a dual-frequency simplex.

When you press the tangent, the radio transmits at frequency 1, and when depressed, it switches to receive mode at frequency 2. In contrast to the repeater, in the radio station in the dual-frequency simplex mode, reception and transmission are not carried out simultaneously, but sequentially (with the tangent pressed).

Thus, frequency 1 is receiving for the repeater and transmitting for the subscriber station, and frequency 2, on the contrary, is transmitting for the repeater and receiving for the subscriber’s walkie-talkie.
