[time-nuts] From GPS World - Lightsquared has been given the goahead

[paul swed]

True enough there will be three systems heck many channels also.
But that reality actually means my magical HP 3801 may not work or could

So how do we hack those new receivers for time-nuts purposes for $29?
Regards
Paul
