Hello!

I'm running GNURadio/OpenBTS with Ubuntu Linux and an external clock
with 64MHz.
Now I want to use an external oscillator with 10MHz.

Is it possible to run the USRP and the daughterboards (RFX1800) with
this frequency?
I read the article about Clocking
http://www.gnuradio.org/trac/wiki/UsrpFAQ/Clocking

The OpenBTS application has similar lines:
self.refclk_divisor = 16
return 64e6/self.refclk_divisor

I changed it to

self.refclk_divisor = 2.5
return 10e6/self.refclk_divisor

Is this modification correct?
Are there any other things I have to mind?
