Thanks, we are using an arduino with a trackuino shield. Total out put 300mW but we have a very good twin lead j-pole antenna built by your truly. Upping the power could be good, but at that altitude the difference is minimal, also more power means more weight which is our enemy (our current set up weights 200g)
I am working on a near-space balloon project for school and this will be our fourth launch. We have collected data, tried going really high (99,011 feet) and now we are going for distance.We are planning on launching from the San Francisco Bay Area and going east, if all goes well it should end up going of the east coast by the second night. Once the balloon gets about 200 miles of the coast we will lose contact with it until it gets to Europe or Africa, if it gets there.
The idea came up of using a satellite repeater but that would possible mean we can't use regular ground based repeaters. The idea we have is to time our launch so there is a satellite over head of at least part of the way over the Atlantic and we can get an update. The two proposed ideas to do this are having two radios (which means more weight ) or switching channels at a certain time or place (complex).
Does anyone know of any good inexpensive 2 meter magmount mobile antennas at HRO?
