I've seen that. There's a whole family of cheap DIY project modules that run Linux and emulates a PC. I've got some designs that exploit the USB engine on the PIC uControllers as modern incarnations of the rudimentary communications line. This stuff is advancing so rapidly that one is a little intimidated about carving a new idea into hardware . . . the damned thing is in danger of being obsolete before you get to build anything! Fortunately, just as a hammer will still drive a nail, ingredients that went into past recipes for success in the electronic arts still function as well today as they used to . . . and there's no shame in being skilled at driving nails. I had an uncle who was 6'4", weighed about 230 and hated finish work. He liked to frame houses. Drove nails with a rigging axe . . . one tap to start, two taps to set. His left thumb and forefinger looked like victims of the inquisition. I've often wondered how he would prefer to assemble lumber if he were alive today . . .

Yeah, the transformer with a big and little windings is the giveaway. REALLY neat technology for improving line and load regulation of substantial loads (100 to a couple thousand watts). Use to have one in my darkroom to stabilize the enlarger lamps. But not nearly accurate enough to maintain optimal SVLA charging levels. See: http://tinyurl.com/ckforvu Here's the dropping kit in action: https://www.youtube.com/watch?feature=player_embedded&v=05lRvTY6rXA That's unfortunate. "Chargers" that run that hot haven't been seen for lots of years. Used to have oen that featured 1000w of lamps to set the charging current (about 10A) for a 6v battery out of my '41 Pontiac. For now we're using this: http://www.geniuschargers.com/G7200/specs Those should be just fine Bob . . . ________________________________ Message 6 _____________________________________ Time: 02:28:52 PM PST US Subject: AeroElectric-List: icom i200 squelch From: bob noffs here's the update on my noise problem. i pulled the radio and got at the circuit board adj. for squelch. turned the plastic screw from 12 oclock to 9 oclock. that totally eliminated the awos broadcast unless i pulled the volume knob to cancel squelch. turned the screw bach to 11 oclock and that seemed to fix my problem. no more noise at higher rpm. thanks for the help. bob noffs ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message aeroelectric-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/AeroElectric-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/aeroelectric-list Browse Digests http://www.matronics.com/digest/aeroelectric-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
