Superbox Khz code no longer receiving

[Palerider]

Hi, I'm in an n*l area in Kildare using a Super Box, Doing an automatic scan will not reveal any channels however a manual scan takes almost all in for saving, the problem is that a number of channels were coming in on 394750 khz ( eg S*y drama , Ni*k Toons, S*y family ) , would anybody on this forum know which Khz these channelsare now coming through on to allow me manually scan and save..?

Much obliged in advance.
