Bill, I havn't been plugging in ALON/ALAT, sorry I can't help there. My predictions of best time to listen are based upon when stations have successfully received data, ... its retrospective not prospective. Looks like MA 9 to 32, ... I'd say start at MA0 and keep going until MA32, and capture what you can.
