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.
