A selection of flyers from Rave events from my hometown of Birmingham in England. We had some top Rave venues in Brum including The Institute, Aston Villa Leisure Centre, The Rag Market, The Muhammed Ali Centre in Handsworth, Porsche Nightclub in Small Heath, Small Heath Leisure Centre, and for the people that rememeber the real Old Skool there was Coast To Coast above the old Central TV studios and the Marco Polo bar. The best events were the Pandemonium Andromeda Raves, Dance Planet 'The Detonator', the Starlight and Obsession events and last but not least the 'Time' Raves in 1991. This upload is dedicated to the real Birmingham Old Skool Ravers, a shout out goes out to Rob B, John K and Mark W. Music is the first 14 minutes from Manchester's number one, the mighty 'Stu Allan' and his set from Pandemonium Andromeda 6 at the Aston Villa Leisure Centre.</p><p><strong>Video Rating: 4 / 5</strong></p><p> <object

I actually own a lot more than this, but these are all the Pandemonium flyers I could find. I have been a hoarder from an early age, so naturally I have thousands of flyers in the loft and this was all I could find until I got pissed off. Anyone who went to any of the Pandemonium nights will know what special nights they were, they never held back with anything, you were always guaranteed a banging night, from the one off nights at Telford Ice Rink, Birmingham Hummingbird, Aston Villa Leisure Centre, The Que Club, as well as the awesome club nights at the Birmingham Institute (I never missed a night unless there was a big rave on somewhere) J-Jays in Wolverhampton, Mr B's in Willenhall, as well as teaming up with other promoters like Quest etc... Definately one of my favourite promoters along with Fantazia, Obsession, Dance Planet, Starlight, Universe, Amnesia House, Fibre Optic and Dreamscape. This video is dedicated to the Pandemonium promoters, resident MC's Bassman, Lenni and the main man Ranski, all the DJ's that played and most of all the 'Pandemonium Crew' that made that special vibe that only Pandemonium could create. Music is by 1) Sly T and Ollie J - Help Me, 2) Force Mass Motion Esthisis.</p><p><strong>Video Rating: 4 / 5</strong></p> ]]></content:encoded> <wfw:commentRss>http://www.m6ceb.com/old-skool-rave/birmingham-old-skool-rave-flyers/feed/</wfw:commentRss> <slash:comments>0</slash:comments> </item> <item><title>Introduction to Ham Radio : What to Record in Your Ham Radio Logbook</title><link>http://www.m6ceb.com/amateur-radio-articles-and-videos/introduction-to-ham-radio-what-to-record-in-your-ham-radio-logbook/</link> <comments>http://www.m6ceb.com/amateur-radio-articles-and-videos/introduction-to-ham-radio-what-to-record-in-your-ham-radio-logbook/#comments</comments> <pubDate>Sat, 18 Feb 2012 10:28:40 +0000</pubDate> <dc:creator>admin</dc:creator> <category><![CDATA[Amateur Radio Articles and videos]]></category> <category><![CDATA[Introduction]]></category> <category><![CDATA[Logbook]]></category> <category><![CDATA[Radio]]></category> <category><![CDATA[Record]]></category> <guid

Even in the human era we have passed through cataclysmic times of both fire and ice, destruction and rebirth; recorded throughout the world in legends and religious texts. Are the current weather events part of that natural wave pattern of upheaval and stability, man-made global warming, a cyclical eruption of the sun, or are there clear manufactured patterns emerging? The HAARP project has been shrouded in secrecy and speculation since its inception. Despite recent high-profile attempts to access its inner workings, only more questions continue to emerge. Conclusions about its operational capacity are those that have caused a drift toward "conspiracy theory." Defense operations have quite a history of harebrained boondoggle schemes that never become operational. However, weather modification (and weaponization) has been consistently discussed and researched by the military and the Elite to a level that indicates there is something worth pursuing. Let us look at a few things we know for certain: HAARP is a military installation Officials downplay the facility as pure "basic or exploratory research" — working with Alaska University, Fairbanks — possessing no military applications. Yet, the United States Air Force, Navy and DARPA scientists populate the remote site in Gakona, Alaska. It is also part of the Strategic Defense Initiative, which answers to the Department of Defense, and makes it a component of "Star Wars <b>...</b></p><p><strong>Video Rating: 4 / 5</strong></p> ]]></content:encoded> <wfw:commentRss>http://www.m6ceb.com/amateur-radio-articles-and-videos/introduction-to-ham-radio-what-to-record-in-your-ham-radio-logbook/feed/</wfw:commentRss> <slash:comments>0</slash:comments> </item> <item><title>Radio repeater  </title><link>http://www.m6ceb.com/amateur-radio-articles-and-videos/radio-repeater/</link> <comments>http://www.m6ceb.com/amateur-radio-articles-and-videos/radio-repeater/#comments</comments> <pubDate>Fri, 17 Feb 2012 09:31:07 +0000</pubDate> <dc:creator>admin</dc:creator> <category><![CDATA[Amateur Radio Articles and videos]]></category> <category><![CDATA[Radio]]></category> <category><![CDATA[repeater  ]]></category> <guid

transmits and receives at the same time simultaneously A duplex repeater uses two radio frequencies an Input frequency which it monitors for signals and an Output frequency on which it retransmits the received signals at a higher power or higher amplitude br The input is the frequency on which mobile radios or hand held radios transmit to reach the repeater The output is the transmitter frequency for the repeater which repeats the audio from the received signal on the input br The fact that the transmitter and receiver are on at the same time means some electrical isolation must exist to keep the repeater s own transmitter from degrading the repeater receiver If the repeater transmitter and receiver are not isolated well the repeater s own transmitter blinds the repeater receiver Example the problem is similar to being at a rock concert and not being able to hear the weak signal of a conversation over the much stronger signal of the band br Part of isolating the transmitter and receiver is keeping the input and output frequencies distant The further apart these two frequencies the easier it is to keep the transmitter from interfering with the receiver This is an engineering problem with many possible solutions br Frequency separation input to output br There is no set rule about spacing of input and output frequencies for all radio repeaters Any spacing where the designer can get sufficient isolation between receiver and transmitter will work br The narrowest documented spacing found in preparing this article is a system dismantled in the 1980s One channel used on the Riverside County California Sheriff s Department system which was replaced by an 800 MHz trunked system used 158 760 MHz as input and 159 090 MHz as output a spacing of 330 kHz The station callsign was KMH971 It is unusual to see systems with input and output spaced this closely It is believed working systems have been spaced as close as 175 kHz br In some countries under some radio services there are agreed on conventions or separations that are required by the system license In the case of input and output frequencies in the United States for example br Amateur repeaters in the US 144 148 MHz band usually use a 600 kHz 0 6 MHz separation br Systems in the 450 470 MHz band use a 5 MHz separation with the input on the higher frequency Example input is 456 900 MHz output is 451 900 MHz br Amateur repeaters in the US 420 450 MHz band use a 5 MHz separation with the input being either on the higher or lower portion of the 440 450 segment of the band the standard changes regionally Example output is 444 400 MHz input is 449 400 MHz br Systems in the 806 869 MHz band use a 45 MHz separation with the input on the lower frequency Example input is 810 1875 MHz output is 855 1875 MHz br These are just a few examples There are many other separations or spacings between input and output frequencies in operational systems br Same band frequencies br Same band repeaters operate with input and output frequencies in the same frequency band For example in US two way radio 30 50 MHz is one band and 150 174 MHz is another A repeater with an input of 33 980 MHz and an output of 46 140 MHz is a same band repeater br In same band repeaters a central design problem is keeping the repeater s own transmitter from interfering with the receiver Reducing the coupling between transmitter and input frequency receiver is called isolation br Duplexer system br In same band repeaters isolation between transmitter and receiver can be created by using a single antenna and a device called a duplexer The device is a tuned filter connected to the antenna In this example consider a type of device called a band pass duplexer It allows or passes a band or a narrow range of frequencies br There are two legs to the duplexer filter one is tuned to pass the input frequency the other is tuned to pass the output frequency Both legs of the filter are coupled to the antenna The repeater receiver is connected to the input leg while the transmitter is connected to the output leg If the right specifications are chosen the duplexer has a narrow enough filter to prevent the repeater s receiver from being overloaded by its own transmitter By virtue of the transmitter and receiver being on different frequencies they can operate at the same time on a single antenna br Any anomaly or fault with the antenna or antenna feed cable will reflect transmitter power back into the receiver possibly causing the receiver to be overloaded The reflected power will quickly exceed the duplexer s filtering ability br There is a relationship between the frequencies on which a duplexer filter is utilized and the physical size of the filter A band pass duplexer for 45 MHz will be much larger than the same design built to work at 860 MHz br Combining system br There is often not enough tower space to accommodate a separate antenna for each repeater at crowded equipment sites In same band repeaters at engineered shared equipment sites repeaters can be connected to shared antenna systems These are common in trunked systems where up to 29 repeaters for a single trunked system may be located at the same site Some architectures such as iDEN sites may have more than 29 repeaters br In a shared system a receive antenna is usually located at the top of the antenna tower Putting the receive antenna at the top helps to capture weaker received signals than if the receive antenna were lower of the two By splitting the received signal from the antenna many receivers can work satisfactorily from a single antenna Devices called receiver multicouplers split the signal from the antenna into many receiver connections The multicoupler amplifies the signals reaching the antenna then feeds them to several receivers attempting to make up for losses in the power dividers or splitters These operate similarly to a cable TV splitter but must be built to higher quality standards so they work in environments where strong interfering signals are present br On the transmitter side a second transmit antenna is installed somewhere below the receive antenna There is an electrical relationship defined by the distance between transmit and receive antennas An desirable null exists if the transmit antenna is located exactly below the receive antenna beyond a minimum distance Almost the same isolation as a low grade duplexer about 60 decibels can be accomplished by installing the transmit antenna below and along the centerline of the receive antenna Several transmitters can be connected to the same antenna using filters called combiners Transmitters usually have directional devices installed along with the filters that block any reflected power in the event the antenna malfunctions The antenna must have a power rating that will handle the sum of energy of all connected transmitters at the same time br Transmitter combining systems are lossy As a rule of thumb each leg of the combiner has a 50 3 decibel power loss If two transmitters are connected to a single antenna through a combiner half of their power will reach the combiner output This assumes everything is working properly If four transmitters are coupled to one antenna a quarter of each transmitter s power will reach the output of the combining circuit Part of this loss can be made up with increased antenna gain It is important to note that 50 watts of transmitter power to the antenna will make a received signal strength at a distant mobile radio that is almost identical to 100 watts br In trunked systems with many channels a site design may include several transmit antennas to reduce combining network losses For example a six channel trunked system may have two transmit antennas with three transmitters connected to each of the two transmit antennas Because small variations affect every antenna each antenna will have a slightly different directional pattern Each antenna will interact with the tower and other nearby antennas differently If one were to measure received signal levels this would cause a variation among channels on a single trunked system Variations in signal strength among channels on one trunked system can also be caused by br failed parts in the combiner br characteristics of the design br loose connectors br bad cables br mistuned filters or br incorrectly installed components br Cross band frequencies br Consider the possibility that Amateurs are likely to have been the first to experiment with and to use cross band repeaters br Modern br Cross band repeaters are sometimes a part of government trunked radio systems If one community is on a trunked system and the neighboring community is on a conventional system a talk group or agency fleet subfleet may be designated to communicate with the other community In an example where the community is on 153 755 MHz transmitting on the trunked system talk group would repeat on 153 755 MHz Signals received by a base station on 153 755 MHz would go over the trunked system on an assigned talk group br In conventional government systems cross band repeaters are sometimes used to connect two agencies who use radio systems on different bands For example a fire department in Colorado was on a 46 MHz channel while a police department was on a 154 MHz channel they built a cross band repeater to allow communication between the two agencies br If one of the systems is simplex the repeater must have logic preventing transmitter keying in both directions at the same time Voting comparators with a transmitter keying matrix are sometimes used to connect incompatible base stations br Historic br In looking at records of old systems examples of cross band commercial systems were found in every US radio service where regulations allowed them In California specific systems using cross band repeaters have existed at least since the 1960s Historic examples of cross band systems include br Solano County Fire former Fire Radio Service 46 240 input 154 340 output This system was dismantled in the 1980s and is now a same band repeater br Mid Valley Fire District Fresno former Fire Radio Service 46 140 input 154 445 output This system was dismantled in the 1980s and is now a same band repeater br Santa Clara County Department of Parks and Recreation former Forestry Conservation Radio Service 44 840 MHz input 151 445 MHz output This system was dismantled in the 1980s and is now a same band repeater br State of California Governor s Office of Emergency Services Fire former Fire Radio Service 33 980 MHz input 154 160 MHz output br In commercial systems manufacturers stopped making cross band mobile radio equipment with acceptable specifications for public safety systems in the early 1980s At the time some systems were dismantled because new radio equipment was not available br As links br For decades cross band repeaters have been used as fixed links The links can be used for remote control of base stations at distant sites or to send audio from a diversity voting receiver site back to the diversity combining system voting comparator Some legacy links occur in the US 150 170 MHz band US Federal Communications Commission rule changes did not allow 150 MHz links after the 1970s Newer links are more often seen on 72 76 MHz Mid band 450 470 MHz interstitial channels or 900 MHz links These links known as fixed stations in US licensing typically connect an equipment site with a dispatching office br Vehicular repeaters br Modern amateur radios sometimes include cross band repeat capability native to the radio transceiver br In commercial systems cross band repeaters are sometimes used in vehicular repeaters For example a 150 MHz hand held may communicate to a vehicle mounted low power transceiver The low power radio repeats transmissions from the portable over the vehicle s high power mobile radio which has a much longer range In these systems the hand held works so long as it is within range of the low power mobile repeater The mobile radio is usually on a different band than the hand held to reduce the chances of the mobile radio transmitter interfering with the transmission from the hand held to the vehicle br Motorola for example marketed a vehicular repeater system called PAC RT It was available for use with 150 MHz or 450 MHz hand helds and interfaced with some Motorola mobile radios br In the 1980s General Electric Mobile Radio had a 463 MHz emergency medical services radio that featured a 453 MHz vehicular repeater link to a hand held br There is a difficult engineering problem with these systems If you get two vehicle radios at the same location some protocol has to be established so that one portable transmitting doesn t activate two or more mobile radio transmitters br Vehicular repeaters are complex but can be less expensive than designing a system that covers a large area and works with the weak signal levels of hand held radios Some models of radio signals suggest that the transmitters of hand held radios create received signals at the base station one to two orders of magnitude 10 to 20 decibels or 10 to 100 times weaker than a mobile radio with a similar transmitter output power br Siting as part of system design br Radio repeaters are typically placed in locations which maximize their effectiveness for their intended purpose br Low level repeaters are used for local communications and are placed at low altitude to reduce interference with other users of the same radio frequencies Low level systems are used for areas as large as an entire city or as small as a single building br High level repeaters are placed on tall towers or mountaintops to maximize their area of coverage With these systems users with low powered radios such as hand held walkie talkies can communicate&#13;</p><p>&#13;<br

target="_new" rel="nofollow" href="http://www.onlineradiotv.com/amateur-radio/">amateur radio</a> equipment includes a transmitter and a receiver. Most hams can purchase both in a single device known as a transceiver. New models of ham radios available in the market nowadays features controls and menu systems that are somewhat complex for beginners that basic usage may require close reading of the manual. Transceivers that have analog controls are preferred by novice users since it's relatively easier to operate.</p><p>Most hams are interested on the technical side of radio communication. They easily find amateur radios as an inexpensive hobby because they can actually experiment on making their own amateur radio equipment. Do-it-yourself ham radios are not as complicated as it may seem. The supplies you will need are actually found in the neighborhood surplus shops and hardware stores. The internet is filled with websites that offer step-by-step instruction manuals to build the most basic transceivers and antennas. In a way, building your own ham radio has become an integral part of the hobby. It is good to know that experienced amateur radio club members are generous enough to share their knowledge to novice hams.</p><p>Beginners, however, are advised to get properly acquainted with the fundamental operations of amateur radio equipment before heading toward the more complicated task of build their own. Most of them start the hobby with a hand-held portable radio on the VHF or two-meter band. With such equipment, they can already communicate via several repeaters actively installed all over the world. Transceivers available in the market may cost at around 0 to ,000. Both brand new and used equipments are available for sale in Ebay where there is an active ham radio traffic area. If you are still short of budget, you may try to get a license and still go on air sans a radio. EchoLink is a software that allows you to connect with other hams through the computer, all you need is a headset and a microphone. However, not all hams approve of EchoLink as pure form of amateur radio. Some purists do not even consider it as amateur radio at all.</p><p>Power</p><p>Next to transceiver and antenna, power is another determining factor when it comes to the satisfaction and enjoyment of most hams. An amateur radio equipment may need a few milliwatts up to 1,500 watts of power depending on its size. You can communicate with anyone across the globe with just a few watts of power during day time. But if your idea of technology requires monumental satellites and antenna towers, expect to run high power on it.</p><p>Antenna</p><p>Novice hams usually commit the sin of spending too much on transceivers with all the works while completely ignoring the wonders of setting up a good antenna. High-tech transceivers are of no use without a properly erected antenna. You need not spend a lot on it. Many people around the world connects with just a piece of wire hanging out their windows, you just have to know how to place it. This won't be a problem to beginners who haven't yet passed through their hand-held stage as most of these transceivers have their own antennas anyway. Nonetheless, other portable transceivers used in moving vehicles require at least a magnetic mount antenna. You can set up your antenna in trees, unused flagpoles, camera tripods, rain gutters, aluminum ladders and other possible platforms. Hams enjoy experimenting on various types of antennas. More than the transceiver, it is the <a
target="_new" rel="nofollow" href="http://www.onlineradiotv.com/amateur-radio/">amateur radio</a> equipment that determines the level of frequencies you can reach. The lower the frequency, the longer the wavelength necessary. Long wavelength requires large antennas.</p><p>Hams can take up the same frequency at one point. This is just fine since hams listen more than they transmit anyway. In fact, they get euphoria by the sheer act of reaching a station that identifies itself as coming from the farthest and rarest locations.</p><p>&#13;<br
