You can set the frequency on the freq_xlating_fir_filter at any time.
Just call set_center_freq.

It's also possible to change the user specified filter taps on the fly
too.  Use set_taps, though it isn't often required.

OH, I see - took a minute to figure out this software ;)   We use:

chan_filter_no9 = gr.freq_xlating_fir_filter_scf  ( stuff )

to build it, then call it in your instance with:

chan_filter_no9.set_center_freq ( new_freq )

Cool!  And I see the code that sets the freq has to be in the
same python module def as the instantiation to access it.
