Description

DVMEGA Raspberry PI Single band radio is a radio module that fits without a modem or node adapter directly on the Raspberry PI. The combination RPI and RPI DVMEGA radio is a complete D-Star compatible hotspot with an output power of 10mW. 


The DVMEGA RPI radio comes with firmware and is ready for use. There is one radio available, it is configured to operate in the UHF band.


The DVMEGA-UHF transceiver board utilizes the chip ADF7021. This IC constitutes a complete transceiver for digital data with GMSK modulation. The control of the transceiver chip is handled with a local ATMEGA 328 on the same board. The result is a flexible digital transceiver component with low power for the frequency range from 430 to 450 MHz. The DVMEGA-UHF board handles the radio side and the modulation/demodulation part, the Raspberry Pi is used for the protocol handling of DMR (and future digital modes).


The software for the Raspberry Pi is available in a Yahoo group where G4KLX offers programs like ircDDBGateway and the PCRepeaterController. With these programs and the above mentioned hardware it becomes very easy to construct a local low-power hotspot for digital modes. The benefit is, that due to flexible construction and software, future developments can be made available as well.

描述

DVMEGA Raspberry PI單頻無線電是一種無線模塊,無需調製解調器或節點適配器即可直接安裝在Raspberry PI上。組合RPI和RPI DVMEGA收音機是一個完整的D-Star兼容熱點,輸出功率為10mW。

 

DVMEGA RPI收音機帶有固件,可以使用。有一個無線電可用,它被配置為在UHF頻帶中操作。

 

DVMEGA-UHF收發器板採用芯片ADF7021。該IC構成了具有GMSK調製的數字數據的完整收發器。收發器芯片的控制由同一板上的本地ATMEGA 328來處理。結果是一個靈活的數字收發器組件,在430至450 MHz的頻率範圍內具有低功耗。 DVMEGA-UHF板處理無線電側和調製解調部分,Raspberry Pi用於DMR的協議處理(以及未來的數字模式)。

 

Raspberry Pi的軟件可以在Yahoo組中獲得,其中G4KLX提供諸如ircDDBGateway和PCRepeaterController之類的程序。利用這些程序和上述硬件,構建數字模式的本地低功耗熱點變得非常容易。好處是,由於靈活的構造和軟件,未來的發展也可以提供。
