If all goes to plan we could have a new 13cm and 3cm transponding geostationary satellite in place next spring. Being fixed in position, Doppler should be no issue. I guess the date is a problem (these often slip) and getting it successfully in the right place and operational is in some doubt. With declining solar conditions, this could be just what we need. Of course, the dish can be fixed.

I picked this up on the Southgate News page.
