Projects for Radio Amat. & SWLs (UBP37G)

R189.54

Short wave radio is a fascinating hobby and one that is pursued in a number of ways. One of the main attractions for many short wave enthusiasts is tinkering with different aerials and gadgets in order to get the highest possible performance from their installation. This book describes a number of electronic circuits, most of which are quite simple, which can be used to enhance the performance of most short wave radio systems. Even those who are not interested in building receivers and transmitters are often keen to experiment with home built aerials, and to construct some accessories for their ready-made equipment.

The designs are mainly to aid short wave reception, so they are mostly for both licensed radio amateurs and short wave listeners. The circuits include an aerial tuning unit, audio filters (notch and a highperformance bandpass types), a volume expander, add-on BFO, simple active aerial, a CW./RTTY decoder and other useful projects.

Where appropriate there are details of how to set up and use the equipment, plus notes on any unusual aspects of construction. No precise constructional details are provided, as some experience of electronic construction is assumed. Some of the projects are very simple, and should be within the capabilities of practically anyone who has previously built one or two simple projects, and providing the experience to progress to the more complex circuits.

The circuits covered include:-
- An aerial tuning unit.
- A simple active aerial.
- An add-on b.f.o. for portable sets.
- A wavetrap to combat signals on spurious responses.
- An audio notch filter.
- A parametric equaliser.
- C.W. and S.S.B. audio filters.
- Simple noise limiters.
- A speech processor.
- A volume expander.
