That's interesting information; I'll see if I can figure out how to make
sense of it...

Hrm. TeleMetrum v1.0 units had some extra RF sensitivity due to a
missing capacitor as described here:

Have you been trying to fire igniters via USB? Or just over the RF link?
If it's over USB, then RF can't be involved as there won't be any
transmissions from either end.
Does the TeleMetrum reset when you try? It would beep out the startup
sequence again if it were.
If it's only over RF, then you might send some pictures of the
installation as we may be able to suggest ways to reduce the RF problem.

I'd definitely agree with this plan; fly nothing that you aren't sure about.
