Hello,

I live near a powerful GSM/UMTS base station operating in the 900MHz, 1.8GHz, 
2.2 GHz bands and I have noticed that I have got problems receiving signals in 
these bands with my USRP (using DBSRX daughterboard).
I guess the problem comes from the fact that the interfering signal from this 
base station comes in the A/D converter in all cases as no (selectable) 
pre-filtering is performed depending on the decimation. This is a well known 
problem from software radio platforms.

Do anybody have any advice how I could easily solve this problem ? 

I am thinking to use the IF output from a scanner but the problem is the 
bandwidth is generally limited.

Are there solution for doing selectable pre-filtering (with possibility to 
switch frequency and bandwidth) ?

Thank you for your help

Mathias
