Hi Robin,

the problem with measuring a GPS Signal seems to be the low signal  
level, so (according to my father) I need an amplifier for approx.  
1227 and 1575 MHz - which I don't have and can't build or afford.

Because of that and because I have quite much important stuff to do  
(esp. very hard exams (some for the 2nd time), moving to another flat  
and more) I decided to postpone OpenMoko hardware hacking for a while.

And *even* if I find out *why* GPS does not work for me (e.g. my  
father is simply wrong on the signal level stuff or his HF  
oscilloscopes are far better than he thinks ;-) the problem might be  
very hard to fix - if a fix is possible at all...

So, if you want to use GPS in a short term you'd be better off  
sending-in your Freerunner and getting one with working GPS instead of  
waiting for results I can deliver with in about a month - if I can  
deliver anything at all.

Cheers, Sebastian
