Hi Andy,

I'm the guy who said that.

Actually I based my observation on the fact that i saw an entry of 
10/x/y as the endmost entry on the TangoGPS status line.
Isn't that supposed to mean that it still has fixes from 10 satellites. 
So I thought it must be a SNR issue and the capacitor fix
is supposed to help on that ... right?

This was all guesswork on my part. If somebody could help with how to 
make observations on GPS performance, I'd be glad to
do testing and provide input.

The kernel update is going on as I type this. So will test again today 
if possible. And don't worry ... will be doing the hardware
fix only after OM finally, after all software fixes, decides it will 
still help / otherwise not.
