are there some precise instruction on how to remove the ISM-band filter
on RFX900 boards?
Or someone can provide a description including hardware items and
For example, it's just a matter of un-soldiering the ISM-band filter
chip or it need to be replaced with something?
I am absolutely not an expert in electronics and i am trying to setup

You actually don't need to remove it.
1) Cut the traces to and from the ISM. Make sur to cut them right as

2) Solder a 10 - 100 pF cap in the empty slot parallel to the ISM filter.
