Abstract

Reviews briefly the advantages and disadvantages of tone-in-band SSB in relation to its competitors and describes the receiver developed for VHF. Particular attention is paid both to the `in-lock' performance of the phaselocked loop in the presence of modulation and to the behaviour of the acquisition technique in the fading environment. It is shown both that it is necessary to protect the tone-locked phaselocked loop from neighbouring modulation energy by means of appropriate filtering in the transmitter audio processing and that further protection is required under multipath propagation conditions to prevent the acquisition aid from overriding the modulation interference immunity thus achieved. A solution to the latter problem, called `time hysteresis' is described. Moreover, the techniques are applicable to all three SSB systems
