[time-nuts] Upgrading possibilities for more accurate, precise stable mark ii

[John Franke]

Are you positive there are no locations at your apartment that can receive 
GPS.  I live in an apartment and can get suitable signals with hockey puck 
antennas mounted on four-inch square ground planes placed in various 
windows.  The ground planes are horizontal.  I thought about tilting the 
ground planes, but too much thermal ground noise is received.
