I have about a dozen collars now, a mixture of 30's and 40's. I have a newer 30 that I can't figure out. It seemd to work fine but loses radio signal at about 400 yards. This is with a brand new 320 and also my old 220. I have replaced the long antenna, I have changed out the GPS antennae, removed the software and re-updated...just cannot figure it out. I've never had one do this exactly. Anyone else have any experience with this? Suggestions?
Thanks
Troy
