    <p>O DV4mini basta-se na comunicação, é composto por um AVR que
      controla os sinais recebidos e um ADF7021, para emissão/recepção.
      Todo o componente necessário à comunicação está portanto no dongle
      que recebe a informação, via série, e o stream a ser transmitido
      ou recebido.</p>
    <p>O software necessário serve tão somente para as pequenas coisas
      (grandes neste caso) informar o DV4mini de quais as frequências
      selecionadas, fazer o bridging entre a internet e o dispositivo e
      funcionalidades próprias das redes, como o sejam a captura
      (ligação) a reflectores.</p>
    <p>Sucintamente e sem alargar muito a questão técnica é este o
      funcionamento do DV4mini.</p>
    <p>Por curiosidade; a DVMega radio usa o mesmo ADF7021 no seu andar
      final, a diferença é não usar o AVR e sim as portas GPIO da
      Raspberry para comunicar com um PIC afim de receber e enviar o
      dito trem de pacotes, a restante utilização que no DV4 está no AVR
      nesta última está no software utilizado para a comunicação
      MMDVMHost para DMR e ircDDBGateway para DSTAR.<br>
