Thought I had read I could use a 1k4 dish with port 2 of a 1k2 hooked to the input port of the 1k4 to get the 61.5/72/77/110 sats, but when I run my check switch it fails to show the 110 on one Rx it shows a 1k2 for port 4 but only says conn, on the other two rx's it just shows port 4 as nc. can this be done as is or will a dpp44 be needed, or just get a d500 with a dp single pointed at 110?
