Yeah,
that why this Hobby is so interesting. U can spend lot of time
experimenting with different things, HF, Hardware and lot off old Software.
It's interesting to see how efficient some of the old Software is written.
Also there are lot of different ideas and approaches to the whole AX.25
Stuff.
And u have the chance to implement your own ideas, especially with Linux.
I myself have a few ideas that I want to implement in the future (
Software and Hardware side).
But before that i need a better understanding to all that Stuff.
Do u can more about the security issue ?
