They need more that a coordinated frequency. They need a launch vehicle. They need a track record. They need a launch site.
Googling Neptune 30, Tubesat, Spaceport Tonga and anything else on their web site reminds me of a circular reference in Excel. Colour me suspicious. -----Original Message----- From: amsat-bb-boun...@amsat.org [mailto:amsat-bb-boun...@amsat.org] On Behalf Of W4ART Arthur Feller Sent: August 5, 2009 8:27 PM To: Mark Spencer Cc: amsat-bb@amsat.org; Mark Thompson Subject: [amsat-bb] Re: Fwd: Launch your own satellite for only eight grand Please, take a look the world Table of Frequency Allocations. An extract applying to the amateur-satellite service is included as an Annex in: http://www.iaru.org/satellite/sat-freq-coord.html . (The paper is worth reading, too!!) A more complete overview of the radio regulations is available online thanks to the good folks at the International Radio Club in Geneva: 4U1ITU. See: http://life.itu.int/radioclub/rr/frr.htm . Happy reading. Planning and using radio frequencies to maximize use and minimize interference is a very complex subject that has been developing for more than a century. There's a lot of substance to know. All I am suggesting is that the TubeSat folks and their prospective customers may need to do some good frequency planning before getting to deeply involved. I hope this helps. 73, art.....
