The initial input stage was based on an existing TV 'turret tuner' design,[vi] with manual selection across 14 bands spanning 110–250 MHz. How do you pick the right TV signal meter? [4] The first three were described in The Post Office Electrical Engineers' Journal. [3], As this was the horizontal deflection, the magnetic field lines were almost vertical. [6], A new detection system was required and this would rely on detecting leakage signals from the local oscillator used in superheterodyne radio receiver circuits. Poor signal / snowy picture / distorted sound. On the border between two network areas, a TV of this period might, at most, be receiving four channels. They also had an automatic gearbox, to ease the task of driving slowly down urban streets.[7]. The van contained a team of three people, "including a radio expert and a local Post Office official" and was equipped with a number of aerials that could be adjusted to pinpoint a signal being given off by a television at a specific address.
