No problem.  When you install the filter you set the "cut in" frequency with

the utility.  Keep in mind the actual width of the filter vs the "named" 
frequency, there IS a diffference.  There is documentation somewhere or you 
can measure it, or I can look it up in my notes.  I usually set my filters 
to "cut in" a bit above their actual width.  For instance, the 250 filters 
are really 365 (if I remember correctly, and this is probably the one that 
is the fartherest off. So I set it to cut in at 400 (good to know the freqs 
because the 400 is about 435 so you DO NOT need both the 250 and the 400, 
they are virtually the same).  As you narrow the bandwidth via the front 
panel the radio automatically switches to the next filter as you reach your 
specified cut in frequency (and the filter currrently in use it displayed on

the front panel).  You don't have to remember anything or turn it on 
manually, it is all automatic.

I have the 2.7, 1.8 (set to 2.0 cut in), the 500 (set to come on at 550 I 
think), and the 250 set to come in at 400.  I will be buying the 1000 next 
so I have a bit wider receive when scanning for RTTY or CW, then narrow the 
bandwidth if needed to work them.
