Is APRS analog or digital?
Could you please clarify for me whether the APRS system is an analog or digital technology? I'm trying to understand the fundamental nature of its signal transmission and how it differs from other communication protocols. Understanding this distinction will help me grasp the capabilities and limitations of APRS in comparison to other technologies. Could you elaborate on the characteristics that define APRS as either analog or digital?
