    How to Use Semicolons

    I remember throughout high school i could never figure out how to use a semicolon but as moved on to uni i learned how to properly use these little fuckers. It’s actually quite simple.

    There are 2 ways to use semicolons properly:

    1. To connect two independent clauses

    Independent clauses are series of words that could stand alone as complete sentences. When you have two otherwise complete sentences that you want to connect to form one long sentence, use a semicolon between them.

    Example: This could be a complete sentence; this could be another. Another example could be: Twelve workers started the project; only 3 remain.

    Now if you were to add “and” in the middle then you would need to change the semicolon to a comma.

    Example: Twelve workers started the project, and only 3 remain.

    2. To serve as a super comma

    When you have a series of three or more items that normally would be separated by commas except that each individual item already has a comma in it, you use the semicolon between items.

    Example: We visited Pago Pago, Western Samoa; Curitiba, Brazil; and St. George, Utah.
    Example: The trio’s birthdays are November 10, 1946; December 7, 1947; and October 31, 1950.
    Example: Her favorite players are Steve Young, a quarterback; Jason Buck, a defensive end; and Ty Detmer, another quarterback.

    As in the examples above, citing places, dates, and people’s names with descriptions, are three very common situations where you’ll see the super-comma usage.

    Semicolons make you look sophisticated in writing and could give people a good impression of you for college papers or paper work at your job. Once i learned how to properly use a semicolon i started having professors compliment me on my work more and i’ve been getting better grades in my English course.

    Hope this helped.

  • An Attempt at Eliminating Pedophilia

    An Attempt at Eliminating Pedophilia

    An Attempt at Eliminating Pedophilia

    From 1962 to 1972, two East Germans by the names of Dieter Müller, Fritz Roeder, and Hans Orthner put forth a surgical procedure that they theorized would cure pedophilia. Based on past studies done on rats, they planned to lesion the ventromedial hypothalamus in the brain. This has been shown to cause rats to become overweight and lose sexual interest. Eventually, they received permission from the government to test the procedure on repeat offenders. When these offenders were put on trial and convicted, they were given several options:

    • Indefinite jail sentence
    • Experimental brain surgery
    • Castration

    Needless to say, most of them chose to have the brain surgery. They performed the stereotaxic lobotomy of the ventromedial hypothalamus by drilling through to the specific location, inserting an electrode, and running a current to destroy the VMH. The majority of the procedures done were unilateral, that is they only destroyed one side of the VMH. Only one or two were bilateral, where they destroyed both sides of the VMH.

    After six months, they did a follow-up with the participants and found that pretty much all of them had no more pedophilia. Their procedure was labelled a success and was allowed to run by the government for many more years.

    They then took their results and presented it at a psychology conference, where they were immediately condemned. Not because of any ethics issues, but because of scientific issues. Past VMH lesions performed on rats were bilateral and destroyed both sides. It was accepted that unilateral lesions had almost no effect. Their response? “We didn’t want our participants to become overweight.” They made a huge false assumption. The VMH affects both appetite and sexual desire in conjunction, not individually. If the participants did not become overweight, they probably didn’t actually have reduced/eliminated sexual desire.

    There are two main reasons why they achieved the results they did. First, the offenders could have been lying so that they wouldn’t have to go to jail or face castration. Second, the placebo effect may have given the offenders the feeling that they were cured, but eventually it wore off.

    A fellow by the name of Gunter Schmidt, after a grueling process, convinced the government to give him access to contact the participants. He conducted interview to determine if any change in the offenders’ behaviours actually happened. Almost all of the ‘cured’ pedophiles were still exhibiting pedophilia. After that study was carried out, the government immediately pulled the plug on the procedure.

    So can VMH lesions cure pedophilia?

    Yes. Bilateral lesions are proven to eliminate any sexual desire.

    So why aren’t any bilateral VMH lesions done?

    Ethics. It can destroy who a person really is, and although many people disagree, dignity is still given to offenders.

  • Antenna Connectors

    Antenna Connectors

    Antenna Connector

    As you may well know there are many different types of RF connectors. These range from your basic TV antenna connector right up to connectors designed for high powered transmitters. In this guide I will go over a few different types of RF connector and where you are most likely to come across a certain type of connector

    The “F” Connector

    This connector is commonly used in satellite TV applications it has a 75 Ohm impedance and is well suited for digital TV systems and such. It attaches by simply screwing onto the socket

    F connector:

    Belling Lee Connector

    You are probally famillar with this connector as it is the common tv aerial connector. It has a impedence close to 75 Ohms and does suffer from impedance mismatch between plug and socket. They are rare with modern digital TV receivers due to this fact. It attaches by simply sliding into its socket

    Belling Lee connector :

    BNC Connector

    Commonly found on scanners and some CB transceivers it is available in both 50 and 75 Ohm variants, it is a bayonet type fitting and the connector fits by pushing on and turning half a turn clockwise till it latches into place

    BNC connector :

    “N” Connector

    The “N” connector is commonly used with transmitters, especially on the UHF bands. it is also one of the only connector types able to carry microwave frequency signals. It finds use in homebrew long range WIFI setups. it simply screws onto its socket

    N connector :

    SMA Connector

    The SMA connector is commonly found on WIFI equipment as it can handle frequencies up to 18 GHz. This connector has an impedance of 50 Ohms and can also be found in a reverse variant. The normal variant has a centre pin on the plug and a mating hole in the centre of the socket, however in the reverse variant the pin is in the socket and the mating hole is in the plug. they attach by simply screwing onto the socket

  • FM and TV DX

    FM and TV DX

    FM and TV DX

    Basically DXing is the art scanning the airwaves for distant signals. There are many forms of DXing, including AM broadcast band, shortwave, FM broadcast band, and even TV DXing, to name a few.

    Always, the goal is to pick up stations from as far away as you can. You are probably wondering how long distance tv and fm reception is possible, well it all depends on the weather and the seasons that effect signal propagation at different times of the year, we can enjoy almost every form of signal propagation known to exist.

    FM signals sometimes get “ducted” over great distances by various weather phenomena. Signals sometimes bounce off of highly ionized patches in the ionosphere known as sporadic E clouds, enabling reception of signals from 1,500 miles and sometimes beyond. FM signals even bounce off the ionized trails left behind by meteors as they burn up in the atmosphere. with the right antenna setup anyone can receive long distance signals

    Beginners Guide to Radio Scanning

    Daktologist’s Beginners Guide To Radio Scanning

    Before I begin I would like to say that this is from personal experience and worked for me but you may have different ideas so please add your ideas :). This guide shows my current set up and deals with setting up a desktop scanner due to the slightly more difficult set up required, although hand held scanners are available they are simple to set up and mainly require you to insert the correct batteries attach the supplied antenna and your ready to go. Unfortunitly in parts of the world scanning is illegal ( parts of Europe from memory. ) so if you get arrested it isn’t my problem, fortunately here in nz you can listen to anything you want apart from encrypted signals so it is no problem.

    Anyway first you will want to find a place for your scanner preferably close to a power socket so you can plug it in and close to where you will put your antenna as you will want to keep your antenna cable as short as possible to prevent signal losses which prevent reception of weak signals.

    The other main thing you will want to do is google the frequencies of things like the police and airport or whatever you want to listen in your area too as this makes things easier than trying to search for the frequencies of things manually as it may take a while. I commonly listen to the cops as some funny shit does happen from time to time, that and it can be handy to know if your about to be raided or what not, and you can listen in on phone calls and the lulz do ensue from time to time especially listening in on people you know, its amazing what you can learn about someone from their phone calls.

    Anyway its up to you really what you can listen to and your scanner can unlock this whole different world of radio you didn’t know existed.

    So what can you listen to other than the cops and the phone calls of that random girl you use to work with you ask? Well apart from law enforcement there’s air traffic, utility’s, fire, ambulance, pagers, your neighbours outdated cordless phone, shipping, the international space station and the list goes on

    Welcome to the world of Radio Scanning

    Receiver

    The Receiver or “Scanner” as it is also known is by far the most important part as if you didn’t have it the rest of this guide would be useless, as you can see in the pic below i am using the Uniden UBCT8 as it is easy to set up and to use especially for a beginner and will get you scanning the airwaves in no time. Scanners either come as a desk unit as mine is or a hand held unit as the pic of my hand held scanner shows

    The Receivers that I’m currently using:

    Desktop Scanner

    Handheld Scanner

    Antennas

    I personally just used a spare TV antenna that i had lying around and it was the cheapest option for me, as you can see in the next pic I have it in the vertical orientation as nearly all signals around here are vertically polarised. You may want to play around with the orientation as the polarisation of the signal you want to receive may be different to what it is for me. It is important that you get the polarisation right as you can go from receiving a strong clear signal in one orientation to no signal at all or at the very most a weak and noisy signal in the other so it pays to check the polarisation before blaming the weak signal on being too far away from its source or a useless antenna

    My Antenna:

    as you can see I have two antennas connected which are connected to the scanner through a splitter ( not shown ) as I’m trying to receive signals from two locations, at times yagi antennas like the antenna on the right can be a pain as they are directional where is the folded dipole on the left isn’t and allows reception of signals from any direction. I mainly have the yagi for receiving the somewhat weak signals from the airport ground control and from the closest city, mainly due to the radio traffic being higher and there being more to listen in on and therefore have it pointing about halfway between the airport and town so I can receive signals from both somewhat while the folded dipole makes it easier to receive signals from nearby as well as strong signals from town

    Cabling

    The cable between your scanner and antenna is an important part as is the choice in cable type. Coaxial cable is recommended as cable losses are lower than just using regular electrical cable or 300 ohm ribbon cable ( old style TV cable ) if you do use ribbon cable ensure it doesn’t come in contact with metal objects such as the antenna mounts as this increases losses. coax can be attached to metal objects as it is shielded. I use RG6 coax usually as it exhibits lower losses than RG59 or similar

    Connectors

    Attaching the correct connector to the cable for your scanner is important as if you get this wrong you cannot connect your cable to your scanner obviously. The two most common connectors are the BNC connector which you push and turn to attach it, and the N connector which is slightly larger and screws onto the socket on the receiver. As you may be able to see in one of the pics below you can see that i am using an F connector to BNC adaptor as it was what i had at the time and these can be an option if you have a TV antenna with an F connector attached to the cable already or if you have a screw on F connector as crimp on BNC connectors need a proper crimp tool to attach them and the crimp tool can be expensive. I commonly use F connectors and an adapter as it is quick and easy to attach to the cable. In case you are asking your self “what is an “F” connector well they are the same as the screw on connector that is on the cable that feeds your satellite TV receiver

    BNC Socket on the back of my scanner

    Balun

    A balun is a impedance matching transformer that converts the balanced 300 Ohm output of the antenna to the unbalanced 75 ohm coaxial cable. If you don’t use a balun then weak signals can be harder or impossible to receive

    The balun that is on my antenna:
