Nano HD History Channel?

[squirtNcider]

I have 129 working with all channels working great except History channel. It says no signal and when I go into the menu, it shows 98 signal and 88 quality but wont lock in. I have got 'no signal' sometimes on other channels but I just go into the menu and let the TP sit for a sec and Ciel locks in and all is good.
Is there just a prob with TP42 which has the History Channel or is there something I can do?

I am having the same problem as well with discovery channel. Have scanned the tp a few times and no luck

Im at my neighbor's house watching both channels without a glitch ;)
Dunno what yall configurations are and if anyone is using a power inserter which is recommended.. gl
That is if you are running the DPP 1000.2

Not running the 100.2, just a diseq and reg oval dish with 3lnbs. History seems to be the only channel that I notice had worked once in a while but not at all lately. With my setup, should I possibly get the power inserter anyways?

I found a power inserter and now I have the channel back.....Didn't improve the Quality, still 87% but the channel now works if anyone else is having the same prob as me.
Thanks above for the info on the power inserter.
