DMR dPMR NXDN digital voice signal demodulator decoder and amateur digital modes from Icom Alinco and Yaesu

There are fewer and fewer signals that can be received with a traditional analogue receiver. Modern digital transmissions have taken over and are establishing themselves as an alternative to analogue ones. The most enthusiastic listeners have already noticed this for some time. The problem is certainly very felt and until now there were no adequate commercial solutions. AOR today offers a digital voice decoder capable of enhancing the classic analogue receiver. This is the ARD-300 multi-digital voice decoder which connects to the IF of the analogue receiver and decodes communications in digital format. ARD-300 allows you to decode digital communications in DMR format (Digital Mobile Radio MOTOTRBO Motorola), ICOM DSTAR GMSK AMBE, ALINCO GMSK AMBE, YAESU C4FM, DCR, dPMR, NXDN, APCO-25 (phase 1, conventional mode). In short, all amateur, professional and military digital formats currently in use. The large eight-character two-line LCD display and the selection keys on the panel allow quick and simple configuration of all operating modes. It is obviously compatible with all AOR receivers but can be connected to any receiver as long as it has an IF output at 10.7 MHz or 45.05 MHz. It works with the 12 volts supplied by a special adapter supplied. It has a high power internal speaker, 700 mWatt @ 8 ?, which when connected to the audio output of the receiver allows easy listening of both analogue and digital signals. The ideal accessory to "rejuvenate" our analogue radios.
