Right. You started all this by refering to European sockets which had to be installed in equipment racks. So I naturally assumed that you were talking about UK specific installation sockets being sold in flea markets in the US. But now I realise that you are talking about plug-in extention sockets, and I notice from the photo that that one has "universal" sockets that will accept US and a variety of European plugs as well as UK ones. Personally I wouldn't touch one of those with a barge-pole. Those sort of "universal" sockets rarely make good contact whilst the meter is clearly for show, it would tell you nothing useful. I'm sure it would not be legal to sell those here as the sockets appear not to have shutters, which probably explains why I've not seen one. I wouldn't touch one, even if I needed the voltmeter. -- You can't have a sense of humor, if you have no sense. |

Terrell writes Do you know that the channel combiners in a CATV head end were wired in odd and even banks, on separate groups to prevent IMD caused in the passive mixing? It might have depended on whose combiners you were using. I hadn't heard about this so, one day (it must have been back in the 80s), I decided to do a quick test to see if it was true. To be honest, I don't think I saw much difference whichever way I grouped the channels. From what I remember, with the modulators putting each out 60dBmV, all the intermod products were at least 85dB down, and were rather difficult to measure quickly. Such low levels of intermod would have had a negligible impact on the overall system performance. How many channels and at what signal levels did you try it on? We had seven six port combiners in two groups of eight for a 36 channel headend. The six outputs were combined in the seventh unit and amplified before leaving the building. It did help in some installations, where HSP were used for off air processing and for stations who would push their character generators to over 100% modulation from affecting other channels. -- You can't have a sense of humor, if you have no sense. |

Terry Casey writes In article , says... In message , Arny Krueger writes "Terry Casey" wrote in message ... A couple of questions regarding that list: Why is the HRC channel spacing offset[1] by 300Hz - 6.0003MHz instead of 6MHz? I don't know. I recall once specially tweaking a UK 8MHz HRC harmonic comb generator (to which all of the TV channels were locked). It was a little above (or was it below?) 8MHz. There was a reason for this, but at the moment, I can't remember what it was. One system where this was done was the old BT Westminster system - probably very useful in an area where I would expect a lot of off-air reception problems. Same lot, in the land of the concrete cows and a thousand roundabouts. ;o)) I don't know what offset they used but, as an example, if you alter the comb to 7.990963855MHz, channel E45 is bang on (663.25MHz) so, if you centred the five off-airs around this using E41, E43, E45, E47 and E49, the worst case error will be +/-36kHz from the nominal frequency. Ah yes. That's certainly one of the reasons for using a weird reference frequency. I recall that certain systems insisted that the four set-top bypass channels had to be close to the standard off-air broadcast channels, because some TV sets would not tune to anything but these. Almost certainly this is what I was involved in. But wasn't it at the same place which ingeniously used a not-quite-8MHz comb reference which was actually derived from one of the UHF off-air channels? As the headend equipment was largely supplied by the 'other' company, I doubt if I would have been involved with tinkering with it (although I'm pretty sure that I did swap one or two of the modulator SAW filters because of the problems which arose when NICAM started). Maybe 'my' comb generator was a replacement. -- Ian |

Someone said the last two years of 405 line signals were generated by an unusal method, I think the word they used was "endearing". What was it? BTW, the BBC shut down TV broadcasts in for World War II, and resumed them at the exact point in the same broadcast after the war. :-) That's very easy to do with film. I should know. I loaded and ran truckloads of 16 mm film on a pair of RCA TP66 projectors in the '70s. I'm sure it is, but as we've already established that the "exact point in the same broadcast" bit isn't true its not relevant. The myth that the engineers simply ceased transmission half-way through a programme and left the station like a sort of Mary Celeste has been widespread, but it is a myth. In fact there was an orderly shut and the film in the machines would have been rewound and put into storage before the staff left.

It still would have been no problem to load and start it at exactly the same frame, if they had wanted to. All hypothetical. As David said earlier, it is a myth that transmission was cut in the middle of the cartoon. Station logs exist that say different. Another myth is that the Television Service resumed in 1946 with the same cartoon. It didn't! The cartoon WAS repeated that day - but it wasn't the first programme. Does it matter? Were you alive to see it, and in their service area? I wasn't and I wasn't. I was a TV broadcast engineer at three US TV stations from the early '70s to the late '80s. I started with monochrome and film, and ended up with 1" Sony color VTRS & RCA TK46A cameras feeding a 5 MW EIRP antenna 1700+ feet AAT. I'm sure that that the point being made was that despite all that had happened to Britain since 1939, we were now picking up the pieces, continuing where we had left off, and getting back to business as usual. Even if it didn't quite happen as reported, there is no doubt that the popular version of the story would have been good for moral. -- Ian |

Terry Casey writes In article , says... I recall that certain systems insisted that the four set-top bypass channels had to be close to the standard off-air broadcast channels, because some TV sets would not tune to anything but these. They would have to be very unusual TV sets! I don't know about 'unusual', but they were a problem. I think there were only couple of budget brands which only tuned 'spot-on' to the UHF channels (xxx.25MHz, in 8MHz steps). One might ask indeed "Why would you need them to do otherwise?" Of course, even our cable set-top boxes could normally only tune in 125kHz steps, but at least that got you to within +/-63kHz of the correct frequency - and that was more than close enough. It was more likely to be, in the case of Westminster, that, when CATV systems rarely went above 600MHz, there was nowhere else to put them, coupled with the fact that the off-air channels were left clear, so it was convenient utilise to this for the n + 2 arrangement by straddling the otherwise blank off-air allocation. A comb of 7.988636364MHz would allow E25, E27, E29 and E31 to be used with +/-34kHz error (off-airs being 23, 26, 30 & 33) Of course, this was all long before the Channel 5 debacle - I can't see a way of interleaving 5 channels around Crystal Palace without involving the allegedly taboo n + 5 scenario - although I've never seen a problem with any set I used directly connected to a CATV network Sets generally seemed to improve a lot in later years. I think that the change of IF from 39.5MHz to the European 38.9MHz made quite a difference to N+/- problems. What surprises me is how well some sets could tolerate having direct inputs of 48+ channels (without them going through the converter UHF bypass filtering). Certainly, in the olden days, when faced with more than half a dozen channels, some sets tended to sag a bit at the knees. But, as you have said, there used to be so many embargoed channels on a cable TV system - no adjacent, no N+/-5, no N+/-9, no sums or differences (with single-ended amplifiers) etc. It's a wonder anyone was able to get more than two or three channels! But wasn't it at the same place which ingeniously used a not-quite-8MHz comb reference which was actually derived from one of the UHF off-air channels? Well, dividing E26 by 64 or E30 by 68 would do the trick. I based my comb frequency on E28, being the centre channel but an off-air lock would certainly produce a very stable result, and the offsets would still be reasonable - +58/-11kHz or +11/-58kHz, depending on choice of off air channel. If this is what they did, they could have used either of those channels from Crystal Palace. Next time I see him, I'll ask the man who will almost certainly know (if I remember!). As the headend equipment was largely supplied by the 'other' company, I doubt if I would have been involved with tinkering with it (although I'm pretty sure that I did swap one or two of the modulator SAW filters because of the problems which arose when NICAM started). Maybe 'my' comb generator was a replacement. My involvement with the Westminster system was at the time of the DTV roll-out (or possibly Broadband Internet, I can't remember which) which coincided with the transfer of the system from BT to ntl, so I never saw the BT headend but I did see the documentation related to it, complete with frequency details. I had little to do with the system in London (I think I only went there once - underground, near Shepherds Bush IIRC). As I said, my involvement was among the concrete cows and the roundabouts. -- Ian |

... American wiring plus wooden houses... jeez. All things considered it works very well, at a cost in copper. My estimated death rate in the UK due to all fires was about 0.8 per 100,000 in the last year for which I have reports, and was (2006) and 0.96 in the US (2007) I have not yet been able to get an exact comparison of death rate due to structure fires in the same year but US homes are not the death traps that seems to be suggested above. US's death rate due to structure fires continues to be declining rapidly for new buildings every year, of which we are still building quite a few. The UK is also enjoying improvements in this area, but with slower rates of improvement and probably lower rates of new construction. Both the UK and the US show disappointing results for structures built in the 1950s and 1960s. |

Even in more modern times developing a stealth bomber was far more difficult and there was a delay of many years between the first stealth fighter and the first stealth bomber. How big a bomber and how unpractical a tool of war is a fighter sized airplane that can't be seen until you are 20 miles off the coast and it's carrying an atomic bomb? Given the lack of effectiveness of bomb sighting and delivery in those days, you needed a lot of big bombers to do any strategic damage at all. The distance from the coast to London is 92 miles so it needs to go 112 miles to drop the bomb directly on London. If it was travelling 100 mph, that would take enough time for it to be noticed and if a fighter got lucky, it would be shot down visually. I thought we were talking about Germany bombing the US. The cargo load of the airplane was about 2000 pounds, about 1/5 of the size of the Hiroshima and Nagasaki (fat man and little boy) bombs, but that does not mean that someone could of built an atomic bomb that would fit the weight critera if one did not care to survive the construction of the bomb and the flight. I now of no evidence that care taken during construction the shielding of the bomb while being delivered was making the bombs that big and heavy. I'm under the impression that most of the gains that were made in minaturizing atomic bombs had to do with the design of the mechanism. After all how much size or weight in shielding do you have on an A-Bomb that you can fire with a mortar or a bazooka? http://en.wikipedia.org/wiki/Nuclear_weapons_delivery "Other potential delivery methods include artillery shells, mines such as the Medium Atomic Demolition Munition and the (very odd) Blue Peacock, and nuclear depth charges, and nuclear torpedoes. An atomic mortar was also tested. Even an 'Atomic Bazooka' was designed to be used against large formations of tanks." More may be known about comparable Russian weapons because of the break down of the Soviet military: http://en.wikipedia.org/wiki/Suitcase_nuke "These devices, "identified as RA-115s (or RA-115-01s for submersible weapons)" weigh from fifty to sixty pounds." While the active materials in an A-bomb are radioactive, they aren't all that radioactive until they become a critical mass. |

"Terry Casey" wrote in message ... In article , says... "Terry Casey" wrote in message ... In article , lid says... [1] UK cable systems mostly use HRC at 8MHz spacing but this is sometimes varied by a carefully calculated amount so that one block of UHF channels coincides almost exactly with the broadcast frequencies. This is done on systems with a by-pass facility to allow a few channels - usually the local off-airs - to be fed directly to the TV giving the subscriber direct access from the TV without needing an aerial. Obviously this block of channels has to be chosen so as not to conflict with local transmitters, so the offset will vary from system to system and can't be fixed as in the US table In case it isn't clear, I should have pointed out that normal cable reception is via a set top box and, of course, I was referring to analogue systems ... The advent of TV sets that could tune the cable channels all by themselves was a game changer. They are used on the continental cable systems but never have been in the UK. Possibly because there is much more encrypted subscription content? We have TVs that will show encrypted content. They have a slot for a "Cablecard" which is a decrypter that is supplied by the content provider (cable company). AFAIK cable company DVRs have two Cablecards inside the box, and they are available for installation in PCs. |

Erm, 405 started before the war and was alone until 1964? Then it continued for another 20 years? Someone said the last two years of 405 line signals were generated by an unusal method, I think the word they used was "endearing". What was it? BTW, the BBC shut down TV broadcasts in for World War II, them at the exact point in the same broadcast after the war. :-) That's very easy to do with film. I should know. I loaded and ran truckloads of 16 mm film on a pair of RCA TP66 projectors in the '70s. I'm sure it is, but as we've already established that the point in the same broadcast" bit isn't true its not relevant. The myth that the engineers simply ceased transmission half-way through a programme and left the station like a sort of Mary Celeste has been widespread, but it is a myth. In fact there was an orderly shut and the film in the machines would have been rewound and put into storage before the staff left. It would have been 35mm film (the BBC didn't have facilities for transmitting from 16mm film pre-war) and thus on nitrate stock. putting it into proper storage would have constituted a fire hazard been in contravention of fire regulations. It still would have been no problem to load and start it at exactly the same frame, if they had wanted to. All hypothetical. As David said earlier, it is a myth that transmission was cut in the middle of the cartoon. Station logs exist that say different. Another myth is that the Television Service resumed in 1946 with the same cartoon. It didn't! The cartoon WAS repeated that day - but it wasn't the first programme. Does it matter? Were you alive to see it, and in their service area? I wasn't and I wasn't. I was a TV broadcast engineer at three US TV stations from the early '70s to the late '80s. I started with monochrome and film, and ended up with 1" Sony color VTRS & RCA TK46A cameras feeding a 5 MW EIRP antenna 1700+ feet AAT. I'm sure that that the point being made was that despite all that had happened to Britain since 1939, we were now picking up the pieces, continuing where we had left off, and getting back to business as usual. Even if it didn't quite happen as reported, there is no doubt that the popular version of the story would have been good for moral. Or an attempt to raise the moral of the citizens after VE day? The word, of course, should have been 'morale'. I'm sure that, even during the war, British morals remained impeccable! TV broadcasting didn't resume until 1946 - a year after VE Day. After the war, it took a long time for life in Britain to get back normal. We were constantly being reminded of austerity and deprivation. For example, lots of things were rationed, and de-rationing didn't begin until 1948. I believe that certain things which has escaped rationing during the war were actually rationed after it ended. I remember sweets coming 'off the ration' in 1953. Meat was the last, in 1954. In 1951, we had the Festival of Britain, which was intended to boost both morale and the economy, and a lavish coronation in 1953. I expect that the resumption of the TV service with a Mickey Mouse cartoon also helped to cheer us up - even though, at the time, it would only be seen by a handful of people in the London area. It could be that the urban legend which followed was actually more effective than the broadcast itself. -- Ian |

"Morality" refers to correct behavior -- not just sexual behavior.

A sexual act takes two, and usually one is a woman. The social effect of WW2 gave women the freedom to engage in such sexual behaviour as well as many other freedoms. It is your attempt to deny the link that is "disingenuous and ill-considered". David. |

Even in more modern times developing a stealth bomber was far more difficult and there was a delay of many years between the first stealth fighter and the first stealth bomber. How big a bomber and how unpractical a tool of war is a fighter sized airplane that can't be seen until you are 20 miles off the coast and it's carrying an atomic bomb? Given the lack of effectiveness of bomb sighting and delivery in those days, you needed a lot of big bombers to do any strategic damage at all. The distance from the coast to London is 92 miles so it needs to go 112 miles to drop the bomb directly on London. If it was travelling 100 mph, that would take enough time for it to be noticed and if a fighter got lucky, it would be shot down visually. I thought we were talking about Germany bombing the US. We were, but you had said that a single small airplane would not be a practical tool of war, and I was refuting that. IMHO a single stealth airplane, seeming appearing out of nowhere 10 minutes from London with an atomic bomb would have been a very practical tool of war. Especially if the US public was led to believe that there was another one headed for the east coast of the US, for example New York City, Boston, Washington DC, etc. Or if there were two such airplanes, one hitting New York from Europe and one hitting L.A. from "Japan" (not directly, obviously), that would have been the end of the war. IMHO one of the big reasons that Japan surrendered after the second atomic bombing was that they were unaware there was no fourth bomb, the first having been set of on US soil. If (again speculation) the US had not invaded Europe in June of 1944, my original comment, and the Luftwaffe had both a stealth bomber and atomic bombs to drop from it, the war would of turned out differently. As for Germany stopping its atomic bomb development program in 1942, how many times did Saddam Huesein start his and Iran stop theirs in the last 20 years? Geoff. -- Geoffrey S.

An awful lot of "ifs" there! As for Germany stopping its atomic bomb development program in 1942, how many times did Saddam Huesein start his and Iran stop theirs in the last 20 years? The US threw enormous recourses at building an atomic bomb, recourses that Germany simply didn't have in 1944. They didn't have the recourses to build a transatlantic stealth bomber either. The fighter (which of course never saw action) was no more than a concept demonstrator, it didn't have the range to reach the UK let alone the US, nor did it have the load-carrying capability to carry an atomic bomb. How long would it have taken Germany, already coming under serious pressure from the Red Army and seriously short of fuel, materials and manpower to develop both? David. |
