Jeff GeerlingAfter you get into ham radio, you stop looking at touristy things and start looking at the antennas on top!

@geerlingguy Same with working with network gear as a hobby (and a job) and staring at access points, network racks, switches, wireless bridges, etc. when out and about and the attempt to identify them ^^'

Gaëtan PerraultSince being deeply involved in my own housing build, I definitely feel this way about most buildings I visit now. 😀
Network and security gear, power runs, pipes and ventilation, antenna and satellites, the works. I especially like seeing this in tourist friendly buildings. They're often historic in some way, so a lot of this gets retrofitted, making the process more interesting.
Joe Pasqua@geerlingguy Jeff, how long can one expect to have to learn/study before being ready to take the technician exam? I want to do it at some point, but don't know how big the investment of time will be.
K5KGT@bitsplusatoms Technician's exam doesn't take much time to study for. It's pretty common sense questions. There are a few guides online that make it easy. You can do it with a couple of evening sessions. Schedule your testing (or find out when it's available) and you can knock it out quickly. General is not much harder, but will take some actual study.
@bitsplusatoms I spent maybe 4-6 hours studying with the ARRL book. Though I also had some basic understanding of a lot of the principles.
