[Discuss-gnuradio] Problem to set RF filter on DBSRX board

[meco1982]

Hi,
I'm a new user on this forum....
I need some help and I hope someone can save me from the madness %-|%-|
I used on USRP 1 the DBSRX daughterboard with discrete success to acquire
DVB-T signal in 800 MHz band.
Now i want to carry on my work on USRP2 to avoid problem with overrun
but....after hardware changes at daughterboard it works very well to see the
signal but I can't set daughterboard RF filter bandwidth to select a
particular DVB- T channel cause in USRP2 there is no method "set_bw()".
Now...I can modify db_dbsrx.c to add this method that modify registers to
set RF frequency bw like the same ".cc" script for USRP1...but after that? I
have to recompile something after that? how can I recall "my" new method in
a python flow graph if the usrp2 class not contain this new method?

Please help me....and I'm deeply sorry if someone thinks I'm an ignorant
:confused:

Thanks,
Domenico
