I guess, it is the right time to start this topic also on this forum as X band is slowly being discovered by more and more satellite enthusiasts across Europe.
What I have to say is the fact, that this band ain`t easy to get mostly `cause the price of the hardware needed.
Peon has access to the pro grade parts from 01/2014, but he mostly focuses on Ku and C band reception. He takes X band very easy and those pro grade parts in his drawer do not make him excited at all even most of us wouldn`t sleep 1 night to try it. But this is what a real professional does. Keeps calm and improves his gear to be used when time comes. :boxing:
I must say, he is as calm as it gets, but I do know for sure that he will start fishing sooner or later. :fishing:

There are DXers such as Feedsat, s-band, femi or Triker we collaborate and exchange our know-how with, to make this band more clearer and available to others enthusiasts. I hope, that sooner or later somebody from Poland will join us!
But for now, I`d like to show you parts you`ll need to get signals from this band, where military communication and circular polarization is used.
