Hi guys,I recently quit Sky after over 20 years with them and returned their loaned Sky Q boxes etc. As I had three Sky+HD boxes in loft I connected two of these to the two tv's here and replaced the LNB in the Sky dish with a universal LNB from Screwfix. I now have quite a lot of Freesat stations on both tv's. I see you have Sky Freesat viewing cards for sale to access more Freesat stations. Are these just plug and play type thing,ie,remove card currently in Sky+HD box,replace with your card and all extra functions/Freesat stations just work ? Or do you have to do something else to get your cards to work ? Paul
