I got a new Craftsman reciever and remote, and hooked it up to the ol' Stanley. You have to disable the old reciever for the new one to work right. I cut the old antennae, and now I have about a 10' range with the new remote, and it only works half the time. But I don't see what would be the "tuning slug" on the Stanley board. What else can I disconnect, or what else can I do? Thanks!!
