We will all miss her, but thanks to all who were involved in the project. It served us well over the past 9+ years and served as an excellent gateway to linear satellite operations with it's excellent downlink signal. I remember fumbling through my first full-duplex linear satellite QSO just under two years ago on VO-52. That success eventually got me hooked!
Carrying the first Mode B linear transponder launched and activated since AO-13 in 1988, the popularity of VO-52 has led to the launch of Mode B linear transponders on AO-73, EO-79, and UKube-1, so her legacy will continue to live on. 73, Paul, N8HM On Mon, Jul 21, 2014 at 11:07 AM, R Oler <orbit...@hotmail.com> wrote: > What a wonderful asset the satellite has been ....built by good people it > accomplished the goal we should all be part of, of "extending the hobby to > others".
