I've got a small 2" screen, portable, hand-held sanyo TV - about the size of a 'kindle' - slightly smaller - it's got a pull-up aerial and takes 4 X AA batteries.It's about 25 years old. Will it be operational when everything goes digital? It's still in good nick.
Many a happy hour spent adjusting the heater voltages on a pair of 6697 valves in a Ampliphase amplifier trying to get the inter-mod products down and the sproggies out of the RF output whilst seeing the water round the ship 'boil' at max RF output. (50KW with 15KV on the anodes)
Mine were air dropped torpedoes and outputs such as you have described would have done peculiar things to airfield and aircraft radars, to say nothing of electrically initiated weapons carried and stored alongside!
On the subject of old TVs.
One of my neighbours uses an old portable, without a digibox and it works fine. I thought she must be mistaken, as our area (northants) switched over months ago. But I have seen it working, using the sets own ariel, so it must be picking up analogue signals from somewhere.
I tried my own TV without the digibox, but couldn't pick up anything?????
