@CityTshwane what an embarrassed. I visited Centurion. I could not find a working street light. More than 50% of the traffic lights are not working. Potholes everywhere I drove. Trees, bushes, grass on all the pavement making it very unsave to drive.
@TheSignalPath I see the Tektronix Diplexer that was used with he 492 and 2755 series Spectrum Analyzers and the harmonic mixers for measurement up to 325GHz if my memory serves me well.
@ForensicsZA Yesterday in peak traffic at an accident scene on the N2 in Cape Town a taxi passing in the yellow lane passed so close to my right the his mirror hit my mirror. All the people faulting the driver with the dash cam in this video will probably be saying that I was wrong.
