is taking time!

L20021218_00121:25:10Taking display record off for a couple of integrations10560EG
to check out the loss of time between reords.
L20021218_00121:28:01Turned display record on again, Menlo Park receiveing feed10530EG

L20021218_00200:33:33Bad trigger on sodium channel only10460EG
L20021219_00001:05:30Ithink there is some signal induced noise in there!10810EG
raising chopper ~2.5km (changing delay from 3394 to 3380)
