Hi Mychaela,

This is extremely good news!

On my end, I've been able to test the FCDEV3B board you sent me, and
I'm happy to report everything appears to be working fine!
I've recompiled fc-magnetite for fcdev3b in the hybrid configuration
and flashed it. Then I tried enabling the radio and do a network 
egistration, which worked without issues. Then I sent an SMS which
was also successful.

Two very minor issues I ran into while compiling:
- on Ubuntu and I presume Debian, /bin/sh links to dash instead of
bash. The configure scripts expects bash, this is trivial to fix.
- mokosrec2bin has to be in PATH. I found it in freecalypso-reveng
and compiled it into /opt/freecalypso/bin

Now regarding the issue of the VCXO calibration, this is slightly less
easy than I thought since the signal emitted by the DUT is not a pure
signal but GSM bursts. I'll have a look into GNU Radio which has blocks
for GSM provided by gr-gsm.

In any case, it's really great to see FreeCalypso hardware working so
well! You've put a lot a work into it, and it's a great success :-)
