What are the advantages and disadvantages of the digital mode ?
The advantages are low-noise and high-quality audio communication (and in commercial or government communications a higher level of security is possible)….in theory. However, for amateur use where there are restrictions such as bandwidth, cost of the radio etc, the technology applied to the EJ-40/43U is rather simple. We admit that the audio from the digital modulation mode in our radio definitely sounds ‘processed’. Due to simplified circuit design, the error-correction rate is not as high as more expensive “cutting-edge” commercial rigs. However, using these boards, you can experience and experiment with the new world of digital audio communications in the amateur bands at a very affordable Alinco price. It is exciting to many to experiment with a new mode. And don’t forget the analog FM audio quality of the DR-135/235/435 series and DJ-596 is superb. The Alinco radios allow you to easily select and use either mode.
