R&D Report 1962-08 : A Band V signal-frequency unit for a V.H.F./U.H.F. field-strength recording receiver. G.J. Phillips, P.T.W. Vance The report describes a signal-frequency unit, for use in Band V (610-960 Mc/s), which forms part of a v.h.f./u.h.f. field-strength recording receiver. Details are given of the mechanical and electrical design of the unit and some problems which arose in its development are discussed. The unit includes two coupled coaxial line resonators for signal-frequency tuning and a crystal-controlled local oscillator, the frequency multiplier of which uses only conventional valves rather than special u.h.f. valve types. Results of performance tests are given which show that the unit meets the requirements of the specification for the complete receiver.
