I'm wondering if I'm having some of the same solder problems that I keep posting a few days again. I don't know much about this type of stuff but every now and then my tracker2 will go into HT mode without the HT jumper in place and will stop tx on my mobile radio and I'm wondering if some the solder points that sticking out are touching each other. I'm thinking of sending mine back but with me working on the road hauling fuel I will have to take time off of work to get to the post office. K7CDL Ron Swart
