Uniden scanners never show the fifth decimal place, so it's perfectly normal to see 770.1562 instead of 770.15625. In fact, you may even see ProScan round it up to 770.1563, nothing to worry about.
Just be advised that you seem to have your squelch fully closed, so you're not going to pick up much of anything except strong local signals. Try turning it down to the threshold, which is normally 2 or 3.
So far these two sites seem to be putting out a very weak signal, so it's the luck of the draw as to whether you'll pick anything up or not. Although Zone 2 is supposed to be Putnam and N Westchester, the signal was actually discovered in the S Westchester area. Perhaps they're just doing some low powered testing in the NYC area.
