Re: ARLA/CLUSTER: Primeiro recetor Analógico/Digital AOR DV1 chega à Europa

[Jorge Santos]

Mas convenhamos, $1300 é um bocado por um recetor. Com respeito ao
multimodo, continua a expectativa sobre a Connect Systems e o CS7000,
embora tecnicamente não ache impossível mas por $200 é que não sei, mas o
Jerry garantia um equipamento para DMR/DSTAR e talvez SF por esse preço.
Mas o DMR e o TDMA são algo de complicado para aplicar num equipamento
FDMA, principalmente a separação feita pelo divisor de tempo.

Só a título de informação e para quem não o saiba os repetidores analógicos
precisam de cavidades para separar a frequência de emissão da de receção
isto para evitar a desenbilização do RX, no DMR a frequência é única como
nos demais mas pode haver uma comunicação no TS1 e o TS2 estar em escuta
num outro TG ou numa conversação privada.


Adenda:

TS = Time slot (espaço atribuido em tempo de frequência)
TG = Talk Group (algo similar aos reflectores na rede DSTAR, groupos de
conversação)
