Check if the agc part of your box is able to handle a frequency shift of 250 khz.
Simply use a valid frequency and change it about 250 khz and do a scan.
In some areas such different frequencies are in use.
If agc is working you need only one frequency. For the special areas agc must kick in.
Some special areas:
7 Kings NTL/EX C&W, 41050 666750 6952
Ealing - London N1L ,41069 642750 6952 NEW 14.11.2006
Hanwell 2 - W.London NTL/C&W, 41047 562750 6887
Oxford 1 NTL, 00020 578250 6887
Oxford 2 NTL, 00020 818250 6887
Stafford NTL, 00015 826250 6887
so does this mean if you are in one of the affected areas that end in 000 or 750 scanning for channels wont be possible?
as the new zapit wont handle these steps in frequencies?
sorry if im sounding numb but i have read this thread a few times now and still come to that conclusion.
