I've been testing my Manhattan, scanned the hell out of 79w looking for it, I thought the Manhattan was skipping over it. I didn't know it had "skipped town" Looks like KTEL is the only regular service left on 79w.
Depending on what the Manhattan firmware does, it may skip over it anyway. My Openbox always did (both Perry's and KTEL) til a few months ago. It still skips KTEL on its new home at 87W every time, and I have no idea why. It finds other narrow transponders reliably as long as the signal is strong.
