Tracking today between Ballarat and Cape Otway, Garmin 296 lost satellites, 300xl carried on happily. Could get satellites back by putting my open hand behind the aerial, velcroed to the front of the glareshield, when I got sick of that put the mobile phone on its side in the same place and all the satellites were there. Halfway acroos Bass Strait they all came back online without help from the open hand or the mobile phone. Strangest thing I have ever seen, thought the 296 had died but apparently it didn't like the satellite geometry.
