Been trying to figure out why radio is appealing to me. The serotonin bump is nice, yeah, but there has to be more to it.
Ultimately, I can't help but feel that it's a different sort of challenge. No routers to contend with, not nearly as much software to futz with, just throw some metal in the air and go. Probably why QRP operations, particularly mobile, interests me too. Somehow, declaring "Maximum firepower!" Just feels like cheating to me.
Besides, it also circles back to electronics, another interest I'm pushing myself back to.
