Why I have no radio contact?

[MarKu]

Hello I have a question, because of the satellite system I used to have several working satellites around Kerbin with an RA-100 relay antenna. Then I let it crash and put it back into a better orbit. Now I have no connection at all to any object (space stations, rovers and probes) in space with an antenna even though this worked. Antennas are extended.  Did anyone have a solution?

Thanks in advance

Really stupid question:  do the satellites have power?
