I lived in (West) Germany in the 1960s and '70s, and I'm sure we could get at least two channels on band III (yes, I know B and G channels are narrower, but not that much). There were some areas with two band III channels, Brussels for instance on E.8 and E.10. With a bit of luck you could get a Dutch channel too or a Frech one in the South. We got three Band III signals in Brussels around 1966 (Belgium French and Flemish as well as France). This of course would not have meant that full area coverage like the whole of the UK would have been possible. Holland had only one channel on VHF, partly because Belgium needed two in Brussels. I think most of Germany had only one too, except if you were close to the border between West and East (or Berlin). For the UK two channels was possible using 405 lines because they used narrower channels, leaving room for more channels to allocate to transmitters. Even then, different polarization was often necessary to separate the signals. gr, hwh |

The same was true of cable systems. As TV sets were incapable of operating with adjacent channels, they carried only alternate channels.

When tv sets became better over time many more channels were used, including most VHF channels. gr, hwh |

But the argument was that VHF gave better national coverage than UHF. If that is the aim then, I suggest, you'd need both Bands 1 and 3 to give truly national coverage of just one network. Its probable that it would be possible to add a second network that only covered the main population centres, as Analogue Channel 5 did on UHF. I don't know how well UK sets worked in the 1960's, but US TV sets were not capable of receiving adjcent channels at one time, so they were not used. For example, channel 2 was used in New York City, while the nearest channel 3 station was in Philadelphia, 90 miles away and too far to be received without a large antenna. I think the next one up was 5 in NYC and 6 in Philly. Generally, UK (and even European) TV sets had a hard time with adjacent channels. Like the USA, the off-air broadcast channels were arranged so that, within the normal service area, there would never be an adjacent channel which was anything like as strong as the channel(s) intended for that area. That was a problem with very early vacuum tube CATV trunk amplifiers that were run single ended. They generated a lot of IMD. Even '60s solid state push-pull Trunk amps had no problem with adjacent channels. CATV converters only made it possible to add more channels to broadcast only TV sets. Some converted to a low VHF channel, (Hamlin, Jerrold, Oak) and others (Eagle) converted everything up to the UHF band. I repaired in excess of 10,000 CATV converters in the '80s, in a four year period along with all of the head end equipment. -- You can't have a sense of humor, if you have no sense. |

Knowing how to do the job takes care of it. It's quite easy to do properly, since the ground is on the end of the outlet. Once it's pushed back into the box and screwed down, the solid wire can't move. That photo is sloppy work, and in most areas you have to use a green wire nut for grounds. Some require a 'greenie, which has a hole through the top, for the wire that goes to the device. When all the wires are connected, the ground is pushed into the back of the box, then the insulated wires. There is enough room in the box for all the wire.

It would have been 35mm film (the BBC didn't have facilities for transmitting from 16mm film pre-war) and thus on nitrate stock.

They had UK outlets, and the 'voltmeter was about 1/2" * 3/4" like the tiny VU meters that were popular 30 years ago in battery powered tape recorders. Now that I *would* like to see a photo of, because I cannot imagine what they look like from that description. Wherabouts on the socket faceplate is the meter fitted? You say they have UK outlets, so why are they not available here? Why would the Chinese make UK sockets and only sell them in Florida? it makes no sense. I'm also still puzzled by the claim that "tourists" are buying socket outlets in flea markets in the US to bring home with them. Socket outlets are simply far too cheap here to make it worth the bother and expense of purchasing with foreign currency and then having to pack in one's weight-limited luggage. "Look what I've brought you as a souvenir of my holiday in Florida, its a cheaply made Chinese copy of a BS1363 outlet", I can't see it somehow! David. |

Wouldn't surprise me, seeing the average American's knowledge of geography. A very insular country. Also, what about the current sabre-rattling over Iraq? There's some right-wing American pols very keen on another war in the Middle East. -- (\__/) (='.'=) (")_(") |

Socket outlets are simply far too cheap here to make it worth the bother and expense of purchasing with foreign currency and then having to pack in one's weight-limited luggage. I would agree with that but then, 'tourists' are a peculiar breed! If they've never looked further than the local High Street or shed they might expect to pay around £5 (or more) http://www.diy.com/nav/fix/electrica...hite-switches- sockets/mk_white_range/MK-Double-Socket-White-13A-9289618 or http://tinyurl.com/7fkucwo rather than a little over a pound: http://www.toolstation.com/shop/Elec...cessories/Cont ractors+Twin+Switched+Socket+5+Pack+Single+Pole/d190/sd2633/p33287 or http://tinyurl.com/65bp6m7 although the price in dollars - $1.85 each - looks much higher. How cheap do they need to be to persuade 'tourists' to buy them ...? "Look what I've brought you as a souvenir of my holiday in Florida, its a cheaply made Chinese copy of a BS1363 outlet", Of course it is quite likely that many that are sold in the UK also originate in China ...! -- Terry |

According to the history books the US entered WW2 because it was attacked by the Japanese. It seems that Michael A. Terrell thinks that Japan is in Europe. The US was already active in the war, but not officially. US volunter pilots were flying missions against both Japan and Germany. THe US was providing equipment and supplies on a "lend lease" program that allowed them to do it for free, without violating the official neutrality polices. US ships were acting as "human shields" to shipping convoys in hope that a U-Boat would miss their target and hit one, allowing the US to enter into the war. Bear in mind that although Roosevelt was pro-war, a lot of people in the US supported Hitler or wanted to remain neutral. He was just waiting for an excuse to enter the war. It was just a matter of time, and a fortunate one. If Japan had not attacked on Dec 7, 1941 and the US did not enter the war until 1943 or 1944, it would not of gone the way it did. Looking back in hindsight, it would have been very likely that if Europe was not invaded in 1994, by 1946 the Luftwaffe would of had a jet engine bomber that was undetectable until 20 miles of the coast, able to fly to New York and an atomic bomb to drop from it. There was a Discovery Channel show where they built a mock up of the design, you can find it on the internet. But you are right, the history books, as least as everyone remembers them says that the US entered the war because the Japanese attacked. Geoff. -- Geoffrey S.

Not a bomber - it would have been the A10 rocket. The A10 was a prosed development of the A4 rocket that was the basis for the V2 bombs that fell on London (as opposed to the jet engined V1 flying bomb known colloquially as the 'doodlebug' - I think the US term is buzz-bomb). To bring this back 'on course' - at least, for uk.tech.broadcast readers - the A10 rocket is mentioned in this historic article: http://lakdiva.org/clarke/1945ww/194...t_305-308.html -- Terry |
