Serviceman's Log
11 August 2008
Occasionally, when I am allowed out by myself, I wander off to the auctions for the day. I always enjoy the experience but I have learnt that what you might gain is at the expense of a day's lost wages and if you do buy something, it's often a pig in a poke with no guarantees.

11 August 2008
This new amplifier module supersedes both the Plastic Power module described in the April 1996 issue and the Ultra-LD module presented in the March 2000 issue. It produces high power at very low distortion. In fact, as far as we are aware, it is the lowest distortion class-AB amplifier that has ever been published.

Planet Jupiter Receiver
06 August 2008
How would you like to try some basic radio astronomy - listening to the bursts of noise originating from the planet Jupiter, or from the Sun? You don't need a lot of fancy equipment to do this, just the simple shortwave receiver described here. ItÂ’s hooked up to a basic dipole antenna (which we describe as well) and to the sound card in your PC, so that you can print out "chart recordings" of the noise signals.
