you have to remove the shielding cover and replace the 1800 band filters with footprint-compatible 1900 MHz filters. It's possible, but requires good SMD soldering skills and access to the right parts. You can also remove the filters completely. This will hovever significantly degrade receiver performance in the presence of out-of-band interferers. -- - Harald Welte <laforge@gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."

phone with filter rework will work right and i also will be able to sniff traffic on 1900mhz witnh burst_ind.but my issue is how to tell code of app_ccch to sniff 1900 mhz instead of 1800 as they share same arfcn no?? On Tue, Nov 20, 2012 at 10:33 AM, Harald Welte <laforge@gnumonks.org> wrote:

we have a flag called ARFCN_PCS that's defined to 0x8000. So if you want to go to ARFCN PCS 512 you set the arfcn to 0x8000 + 512 = 33280
