+ reject/spots freq hf/cw
+
+Then you will get everything EXCEPT HF CW spots, If you am interested in IOTA
+and will work it even on CW then you could say:-
+
+ reject/spots freq hf/cw and not info iota
+
+But in that case you might only be interested in iota and say:-
+
+ accept/spots not freq hf/cw or info iota
+
+which is exactly the same. You should choose one or the other until you are
+confortable with the way it works. Yes, you can mix them (actually you can
+have an accept AND a reject on the same line) but don't try this at home
+until you can analyse the results that you get without ringing up the sysop
+for help.
+
+You can arrange your filter lines into logical units, either for your own
+understanding or simply convenience. I have one set frequently:-
+
+ reject/spots 1 freq/cw
+ reject/spots 2 freq 50000/1400000 not (by_zone 14,15,16 or call_zone 14,15,16)
+
+What this does is to ignore all HF CW spots (being a class B I can't read
+any CW and couldn't possibly be interested in HF :-) and also rejects any
+spots on VHF which don't either originate or spot someone in Europe.
+
+This is an exmaple where you would use the line number (1 and 2 in this case),
+if you leave the digit out, the system assumes '1'. Digits '0'-'9' are
+available.
+
+You can leave the word 'and' out if you want, it is implied. You can use any
+number of brackets to make the 'expression' as you want it. There are things
+called precedence rules working here which mean that you will NEED brackets
+in a situation like line 2 because, without it, will assume:-
+
+ (freq 50000/1400000 and by_zone 14,15,16) or call_zone 14,15,16
+
+annoying, but that is the way it is. If you use OR - use brackets. Whilst we
+are here CASE is not important. 'And BY_Zone' is just 'and by_zone'.
+
+If you want to alter your filter you can just redefine one or more
+lines of it or clear out one line. For example:-
+
+ reject/spots 1 freq/ssb
+
+or
+
+ clear/spots 1
+
+To remove the filter in its entirty:-
+
+ clear/spots all
