asro 220 and dc30 issues

[walkerblacktan]

Hey everyone. I recently baught a used 220 from double u and I baught 2 dc30s from a guy on here. At first everything was working good, but yesterday I started issues. First, my pups were about 30yds away and they were right next to eachother, but after minute the handheld was saying that one dog was to my left. Which wasnt right cus I could see both dogs. Then the pups took off and that same collar said 495 yds while the other said 140. But they were right next to eachother? Thanks

i have a dc 30 collar that i bought used doing the same exact thing i tried updating ,but that didnt work so i took it apart to clean and check connections on antenna and gps antenna connection when i noticed that the little brass tabs on the gps antenna plug in had been snapped by the previous owner.they are very easily broken if not lined up perfectly when pushed into place with the rubber boot it is hard to do without breaking them for me..i had done the same thing myself on a different collar one time.not saying this is your problem ,but it could be.
