I thought I could share this with all of you!! I can still hear that irritating tone of this TV test signal. Broadcasts only started late in the afternoons and if you had nothing to do you could stare at this test pattern and get hypnotized for the rest of your life. We are so spoiled nowadays with technologies like MNet, DSTV and Cable. Back in the days we made Television now we watch it.  Enjoy 😉
