I don't know for sure but I think that one of your TBC's are not working, it should lock on to your signal and sync, I have several of these cards and never used them. I have Kitchen sync's now and it is a no brainer. I see them on E bay a lot and for not much coin.
Also I used to live in a M109 van, had 4 of them on my contact team supporting Armored Cavalry. Brave Rifles. Thank you for your service to our great nation.
