If I recall well it is a 100 pF 603 capacitor.

 You could always buy an RFX1800 and reprogram it as a RFX900.
 to turn your RFX1800 into a RFX900, you can run the command:
 
./burn-db-eeprom -A --force -t rfx900_mimo_b
 
 This way you don't have to solder anything.

 an RFX1800?

[Discuss-gnuradio] Is it possible to buy a RFX900 without the filter?

2009-04-22 Thread Jhon Lee
Hi,

 I read the
discuss-gnuradio  list and know that I need to bypass the filter with a
capacitor and cut away the filter.  I would like to know if it is possible to 
get a RFX900 which has removed the filter when I order it. I might burn the 
board if I do this by myself. The capacitor is so small and I don't think I 
can  solder the small capacitor on the RFX900. I don't have tools. I don't know 
what the proper way is to cut the trace and solder the capacitor.

Thank you,
Jhon
