Mike,
Ok, the fact that you are seeing those ghosts on 44 analogue, means that those hills are doing a little multipath job on the signals from Sutro. The fact that you are receiving a 60 signal on ch 30 is great testimony to the ability of the digital filters in the STB to function in the presence of multipath. 60 is a marginal signal, though, and there is a need to increase your signal to noise ratio at the STB. As you are currently configured, with no pre amplification, you are degrading the input S/N at the antenna by 12 dB due to the 10 dB NF of the STB and the 2 dB loss in the cable. This is leaving you in and around the threshold for the lower frequency channels and well below for the higher frequency.
We can improve things considerably by using a good preamp. A CM7775, with it's noise figure of 2, will increase your S/N by 10 dB, placing you well above threshold.So get that and mount it close to the antenna.
BTW, as an aside, if you want to play with tweaking the antenna pointing, you want to error only in the eastward direction, slightly, not westward. Take a compass and measure the bearing, taking care to remember that the compass will measure 15 degrees too low(here in CA). Should point towards 317 degrees, not less. You don't need to do this if you install the preamp. All for now.
Regards,
John Stephens
