setup problem

setup a blade 7000 combo , a 1.1m dish and a technomate motor , now the dish had no scale on it , my lat is 53 so it states in the motor book to set the elavation at 37 which i did , got a good beep from my satfinder and have installed 28.2 e 26e 19.2 e 16e and 13e , all work fine good pic quality and dish will move to whatever of those sats i pick , my problem is that i cannot pickup 7e 4.8 e or 1w , any ideas why , all help much appreciated.

you have to find thor 1 west that sets all the other sats mate other wise a waste of time , if you get as strong signal on thor 1 west all the other sats will just drop in.
