Yes, I was just checking - grounding both ends of a shield is a common mistake many people, that don't know better, make. I think you've hit the nail on the head - FAST obviously has a new Tune Version 005, for firmware 2.38, that fixes the problems. Odd they don't let everyone know on their downloads page. Unfortunately, sending the unit back for a Tune Version 005 update would be an expensive undertaking for VettenDK. I believe he is in Denmark. FAST needs to put this new Tune Version 005 on the downloads page - and make sure it is listed properly where everyone can have easy access to it. Good to hear your system is finally working better - and about the update.
