It makes no difference to which way the PT Harry is orientated. Double check how far apart the loop is spaced and make sure its parallel. 12 to 14 inch apart. If no joy and running a rc4 decoder, then alter the squelch settings. Speak to Rob at BBK.
I also run a TM2 and the above have all been issues at places where it has not counted.
Mine too is now in the plastic nose in front of servo.
