About Me:
Amateur radio operator specializing in emergency services work, seeking a way to loft a repeater for fire fighting support and other emergency services work. How much mass can I squeeze into a UAV? Solar cells on fabric to run electric motor on a lighter-than-air craft, or multi-engine heavier-than-air with larger than ususal fuel capacity?
Please tell us a bit about your UAV interest

"HOWEVER
SMS messages sometimes can take *hours* to arrive. The SMS service of any carrier can be erratic, and I've observed this on ATT, Verizon, Sprint and T-Mobile. I'm not the only one; a quick search found:…"

"Yeah... don't want to lose that signal, so vertical 1/4 wave is likely best bet"
"Many thanks, OM!"
"Genesis Factor: We're on the scene ANYWAY. This is support to firefighters on the ground in the west, and command get decidedly itchy if they don't have close-in support. We use HF with NVIS (Near Vertical Incidence System) to relay back to a…"
"Ah, perhaps, but Noth666, you don't understand the mission... hams are on the scene anyway, so no need for anything long distance. Therefore, we can work within the restrictive rules currently imposed by the FAA."
"aiming at something small cheaper and without a COS to demo proof-of-concept, then we worry about involving The Powers That Be for a COS and a bigger bird. Plenty of opportunities for using a 400' AGL bird in the work we do."

"Varga, no need to apologize for showing milspec gear. We have civilization available to us because rough men and women stand ready to stand between us and those who would do us harm - updating George Orwell."
"http://solarworld.com/SolarMini-Panels%26Motors.htm $96 + frt gets me six of the 4-3.0-100 panels.. three in parallel, then two triplets in series gets me 200ma at 9v in 56 square inches of wing surface, or raw DC voltage suitable for 20% duty cycle…"
"http://www.rcgroups.com/forums/showthread.php?t=451334 shows it's eminently practical to design and this thread http://diydrones.com/forum/topics/705844:Topic:38565?x=1&id=705... emphasizes <400' and within LOS which is just dandy... so now it's…"
"Keeping an amateur repeater under 400' AGL would be dandy for our needs, so AFAIK from what I read here, no need for autonomous operation as there must be a ham in the field logging the radio traffic anyway, but the $30 autopilot DIY kits I read…"
I'm an amateur radio operator (K7AAY) specializing in emergency services work, seeking a way to loft a repeater for fire fighting support and other emergency services work. We get wildfires and the state rado net has big gaps in canyons and the…
