Just about every aspect at one time or another, from homemade cameras to dark room work. My equipment is all pre-autofocus. Canon AE-1P bodies with many lenses, flashes, filters, gadgets. I get a good shot from time to time. Never did master Morse code for the ham ticket.
Cellular phones make the whole ham thing sort of pointless anyway.
Computers I have been doing this since 1974. I own an original Altair 8800. Designed 'em, programmed 'em in lots of languages, made 'em work, love 'em dearly. Computers have put the bread on my table for many years. I want a two-legged walker.
