Need some more help figuring out why Lady Heather keeps crashing. I think
it may be a flaky Thunderbolt but I only own one. The PC is an i5 Intel
with 8Gb memory and nothing running in background. The log sequence before
crash is first time stamp erros where the log shows within 1 sec the TBolt
jumps from 6 or 7 Sats to zero. Then after a few more timestamp errors, the
date gets corrupted ending with bad RAM, Bad Osc, etc. If I open LH again
(and do nothing to the TBolt) - everything looks good again for about 10-15
minutes and it all repeats again.
This log began with:
# 14:27:28.000 UTC 29 Aug 2017 - interval 1 seconds
#
# tow pps(sec) osc( ppb)
dac(V) temp(C) sats
14:27:28 224866 -8.51365e-008 -0.023564
1.196032 42.660358 8
[similar as line above.....for about 10-15 mins]
After skipping some time stamps it becomes:
# 09:39:47.000 UTC 07 Mar 2019 - interval 1 seconds
Then it goes back to current UTC sometimes with 7 Sats some errors on 0 or 3
Sats:
#! time stamp skipped. t=229340387000.000 last=181406402001.000

ms
Then it goes into 'new receiver mode' and then 'new discipline mode' while
3-7 Sats are visible. This goes on for another few minutes until finally it
shows a series of further corruptions, with minor alarms ending :
#! year error: 60404
