Default Television Magazine (1986/87).

Please does anyone have scans of the spectrum analyser project from late 86/
early 87 Television magazine?

The project is to rearrange a mono portable so a vertical TB derived 30V
sawtooth sweeps the tuner varicaps, while the AGC switches the beam current
line by line to indicate the relative position and amplitude of any signals
the UHF tuner finds.

The project was in several installments, starting (I'm fairly sure) late 86.
Unfortunately the relevant issues seem to have become missing from my

You might google "Poor man's spectrum analyzer" - this is a somewhat
similar project, I believe.
