i haven't been able to lock a signal on RTN either in N,Al. i tuned into the transponders 12140 and 12160 and get pretty strong signals there,one at 60 and the other at 75,but absolutely nothing on the RTN transponders,since reading this thread i tweaked my dish a little more though i think it's about tweaked out. i'm doing a blind scan on 4 to see if maybe it hits it somewhere.i get good signals on several transponders so far and have scanned in the channel AMC-9/3F,some transponders jump up to a 95 signal,i would figure that with signal that strong i would get something on the RTN channels.
