http://www.gnuradio.org/trac/wiki/OpenBTS/DesktopTestingKit said that
the ISM band filter on the RFX900 will need to be removed, as described
in the wiki link. However, I don’t find any information about how to
remove the ISM band filter in theÂ wiki link. I read the
discuss-gnuradioÂ list and know that I need to bypass the filter with a
capacitor and cut away the filter. Does it meanÂ I need to remove the
filter FIL1 and put a 100pf capacitor on C204? Sorry for this basic
question. I am new in this field.
