Well tonight marks the end of era!
The analogue TV transmissions from Winter Hill will begin to switchover to Digital. Tonight BBC2 will be switched over to the digital transmission system. It seems that Manchester is the first area in the country for the national switchover.
For 20 years I worked on analogue televisions, from the old Thorn 1500's Black and White TV's, Decca 2230's, Kortings, Philips G8's and loads of others.
I still know how analogue TV works!
Here are some memorable words and figures that I can still recall from my head...
PAL (Phase Alternating Line), Luminance Delay Line, Chrominance Delay Line, (B-Y) (R-Y), RGB, Subcarrier Oscillator, 4.43361875Mhz, 625 lines, 15.675Khz (line Frequency), 50Hz (Frame Frequency), Static and Dynamic Convergence, Sync Pulse, Colour Burst, Varicap Diode Tuner, Boost Capacitor, Scan Coils, CRT (Cathode Ray Tube), Line Output Transformer, 25Kv (on the final anode), PC86, PC88, AC138, AC139, NTSC (Never Twice the Same Colour), SECAM.
