I want to buy a back-up flight recorder. 63 invalid fixes on a long

year but now I am having problems on about 1 out of 4 flights. The
pattern of invalid fixes is- 4, 2, 30, 0,63, 23,21,49, 8, 10)

Sorry maybe I'm missing the obvious but I'm not following that you mean
by pattern and what the numbers mean. I am not sure it's going to help
but if you want people to try to see something in that could you provide
a link to the IGC files on OLC or somewhere else.

Does the antenna have a good sky view? Have you tried a different
external antenna (if it is using one)?

I'm not sure if you need an full IGC flight recorder or whether a
PDA/PNA with separate GPS would be enough for your needs. But first
choice on my list now for a stand-alone IGC recorder would be an LX Nav
Nano. Actually the Volkslogger would be the backup...to the nano.
