Be cautious with the “Swing Arm Magnifiers” (or even visor magnifiers)! I build a lot of proto-types, so I am not only soldering, but also doing a board layout (as well as possible) at the same time (on the fly). This makes for a lot of concentration and ‘focus’ (HiHi)! As my eyesight gets poorer (and older -- life begins at 40 my ass!) I find that the instantaneous puff of rosin smoke at each solder pad connection makes my eyes instantaneously re-focus. This repeated and magnified change of eye focus can give you some awful and whopping head aches! I have best mitigated this problem by controlling the speed and direction of a ventilating fan. This way, I’m not breathing lead and solder fumes, and I can minimize the puff of smoke eye focus problem! 73! de John PS For the chap in Fresno -- visit M2 Antennas! You can get some good VHF beams and other hardware, when you get your transverters!
