Thanks for the reply. If I can find some free time I'm going to get
graphing going. I also take your point on the badformat pattern.
GPS jammer I had not thought of. Of course anything is possible, but I
live in a subdivision in the midwest USA - and I think most of my
neighbors are the "use the ISP's router" and "call Geek Squad" types. I
will keep a lookout for suspicious unmarked vans bristling with antennae
I think I might bite the $70 USD bullet and just get a new one to try out.
Worst case I will have a backup unit.
