Amateur Astronomy
Manufacturers & Services

Amateur astronomy is one of those hobbies in which I participated avidly for about five years while in the U.S. Air Force and for a couple years after separating. During that time I observed as often as time and atmospheric conditions permitted. While at Robins AFB, in Warner Robins, Georgia, I belonged to the Macon Amateur Astronomy club and spent quite a few Friday evenings operating the museum's/club's 8", 10" and 14" Celestron telescopes both for private observation and for assisting the public after the planetarium show. The club took a couple trips to the Fernbank Science Center in Atlanta and got to look through their 32" reflector, which at the time (circa 1980) was the largest reflecting telescope in the southeast.

Today, of course, private 30" Dobsonians are as affordable as motorcycles. A picture of me and my 8" Newtonian reflector is given below. I ended up selling it after getting married to help pay the mortgage (sold all the R/C stuff, too). Only naked-eye (no longer anywhere near my former 20/15 vision) and my trusty binoculars remain for observing over the past 20 years. Recently, have I begun reacquiring some of my "toys" from yesteryear. I have not purchased another telescope yet, but the good thing is that now the state of the art is orders of magnitude better than where I left off.

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...
