I (DirecTv person) am attempting to help a friend install a 1000.4 dish with EA lnb. The rcvr is an dual tuner HD DVR and is a circle A. Not sure of exact model but is new in the last 2 months. The system was currently being used on only the 110 & 119 sats. 1 rcvr only but using both tuners. 1 coax to the dish. Following the dish install instructions have me a little confused. I am using an in line meter connected to port 2/72 sat. The dish point menu of the rcvr does not even seem to be relative to the EA sats. The 72 signal meter does not seem to work. I have found the 61 sat but on the 72 lnb. Here are my questions.- 1. Will this setup work with one coax . The instructions lead me to believe 3 are needed. Which port if only 1 2. Will the meter work correctly for finding 72 connected in line to the rcvr 3. Check switch shows 61 sat and correct dish but in wrong port 4. Does some type of switch need to be install to use both Sat1 and Sat2 inputs on the rcvr to use both tuners 5. Is a software upgrade required and how Thank You in advance for any help.
