I just got my 722 and still have my older 508's in use. The 508's use channel 3 to feed to other TV's. Have a series of A/B switches I use to switch from 1 508 to other so you can watch either one on any of my 5 TV's.
Now the 722 default coax out on TV 2 is ch 60. I put a splitter to combine ch 3 (from 508) and ch 60 (722 TV2)to same A/B input switch, to be able to switch between both 508's, so any TV can watch either 508 on ch 3 or change to
ch 116 to watch the 722 TV2. Both use UHF remotes (ch 116 is a sister to ch 60). I have a new sony in my daughters room a 4 year old sony in son's room in office newer 22" flat panel Monitor (w/PIP window my PC) the 508's picture is on ch 3 is good (for SD anyway) the 722 ch 116 is just OK, but the older CRT TV 36" sony XBR In basement is snowy and has a hum.
I called dish was told to switch from ch 60 air (default ) to cable ch 73 in system settings. and that 73 is a sister ch 3
has anyone else tried this?

I don't know what others would recommend, but I think it would help to see a diagram if nothing else.

You might have to use some filters in this setup.

Myself, I don't have this type of setup, but I distribute cable tv, modulated security cameras, and tv2 from my vip622 (similar to 722).

I put a lpf600 filter in place to block backfeed into the cable system for the modulated security cams and tv2 output, both of which are on channels over 100. I have no snow or hum or anything, just strong picture to all 4 tvs. I use a splitter/combiner to combine the 3 signals (catv, cams, tv2 from vip622) and then feed the output to another splitter/combiner that feeds the 4 tvs in the house.

Filter sounds like the way to go

I tried to draw freehand looks worse then it is.
how do you determine what filter is needed.

Channel 60 is OTA so you should use Cable channel 73. Just combine both with a regular splitter. On the TV, just change from channel 3 to 73 and viceversa.
