I have a couple Eggfinders and one of them recently developed a problem getting a GPS fix. It synchs OK but then remains in Waiting for fix indefinitely (OK it was there for 90 minutes trying...). The 1S LED does flash at 1 second intervals after a few minutes. Where should I start looking to debug? It's sister synchs and gets fix in a couple minutes. It used to work fine so I reckon it got jarred on landing or some hanger-rash-like damage. If there is a good prior post, I apologize for not finding it. The search didn't seem to turn up much.
