You should get mid 90's on 61.5 tp 29.
Peaking the dish is not difficult, especially a single satellite dish. Have someone watch the screen (Menu,6,1,1) and read the signal strengths to you, or if you can hear the tone go by the pitch (higher is better).
Loosen the 2 bolts that hold the dish to the pole - not too much, just enough to be able to turn the dish. You might even try just warping the dish by holding the right and left edges and gently twisting it from side to side - this will give you some idea of whether to go left or right. Find the highest tone you can by adjusting the azimuth (compass orientation of whole dish unit) then retighten those two bolts.
Next note the setting of elevation and loosen the bolts on either side of the elevation adjustment. Now gently move the dish up and down to get the highest tone on the receiver. It took me about 5 minutes to peak my 61.5 the other night. Signal went from mid 70's to over 100 on some TP's. Tighten up those bolts.
You might repeat the proceedure one more time just for best of the best.
There is NO skew setting needed for one lnb, if the dish has one it should be on 90 degrees.
