> Are there other projects that are more appealing to those who simply want to dabble in electronics? For building electronics, there's the strong ham radio tradition of homebrew and kit assembly of various transmitting/receiving equipment. Also, there are a number of widely used digital modes, such as PSK31, JT9, WSPR, etc.[e.g., 0, 1], several of which are relatively new. They have low data rates but work quite well with narrow bandwidths and low power. And as @PaulHoule mentioned[2], there is also APRS.
