Hi, ive have just purchased a Baby loop from a SK sale, by the looks of the controller its a few years old as it doenst resemble the pics ive seen of recent loops, on switch on it says LOOP ATU P220109 and then will settle on 30178 1.7 on the screen, presume thats the firmware, just checked the controller internally and there is a sticker on the chip showing Baby 10/2015. now I would presume I initially dont need to actually connect a radio to the ATU for initial setup, ive connected a run of Coax to the loop from the back of the ATU, if I initiate an auto tune, I press the B key, input a freq and then press * it says wait, the red light is on but no green light, then after a while it says no resonance, the loop does not move, if I go into a manual tune mode by pressing 1 for 5 seconds, then input the frequency, hit the * key and then move A or B the actual loop shows the freq and 9.9 the loop will actually move in or out but it never actually changes from 9.9, also ive noticed that using A and B works but using 3 and 6 does nothing, so thats where I am, obviously the motor seems fine as I can manually tune it in and out with A and B but im presuming the 9.9 is the SWR, this never changes.

So now im stumped and wondering what to do next
