I am looking to borrow a FreeFlight 1101 GPS from anyone that isn't 
using theirs right now.  This will help me troubleshoot an intermittent 
problem I have had for some time now.

The 1101 feeds into my 2 screen Chelton.  Since day 1, the "GPS failure" 
alarm has come up quite often in flight.  It usually goes away pretty 
quickly.  About 70 hours ago the GPS antenna was replaced, as we found 
out that the 26 dB gain antenna in the plane was the incorrect antenna, 
and so a 40 dB antenna was installed.   The unit operated flawlessly for 
the next 50 hours, and I thought the problem was solved.  The problem 
has come back.  I have checked connections, replaced some connectors, 
and still the problem remains.  Any help on this would be appreciated.

The second question I have is regarding the GPS in the Pinpoint 
GADAHRS.  Would it be worthwhile to connect this GPS in the secondary 
position?  If the WAAS FreeFlight GPS fails in flight, will the Chelton 
seamlessly go to the other GPS?

Puzzled in SC,
