Re: Radios for 1.2 GHz operation



The SEDSAT-1 satellite had a telecommand reciver in that band. It was
constructed at the University of Alabama at Huntsville. Although the
original designers are no longer be at UAH you may be able to get
information through SEDS (Students for the Exploration and Development of
Space) www.seds.org.
