I did the tower signal test in the US many years ago - and passed. Taken at two points on the airport 1000 yards and 1500 yards. Seemed easy enough, but I cannot pass any JAA test, so unrestricted FAA medical and restricted CAA medical.I think someone from Oz posted in this thread once about a tower signal test and said it was only taken at 200 metres. Take time to read the whole thread and see what he had to say.Good luck mate.
