when I first scanned using 1250 steps, it missed CW, CBS, PBS (main) and the Ind. When I did 600 steps, it picked up the rest
I did something similar. About half the local ATSCs were found by using a 1250 step size and then going and re-scanning at 1000 KHz steps and picking up the rest. Funny- if I did a 1000 KHz step size first (before trying 1250), I found nothing.
