hi,

I have chosen the IF frequency to be 8mhz (since I have crystals for
that freq) in my superhet project. So, VFO frequencies should be:

band (mhz) VFO (mhz)
---------------- ---------------
1.8 9.8
3.5 11.5
7.0 15.0
14.0 6.0
21.0 13.0
28.0 20.0

Well..now here is a question: can I use single chebyshev low-pass
filter for all those frequencies? Or maybe it's better to use different
filters with different cut-off frequencies?

thanks!
