Activities For Radio Hobbyists

Amateur radio or ham is largely a hobby activity. The majority of thel hobby time is spent on making contact and having conversations with people in distant regions and from different cultures. Two way communications, identifying their location and station, zone, region and place is the usual custom. This is always followed by other casual communications. If the contact is made for a contest to make two way communication with as many stations or ham radio operators as possible, this all the information that is shared.

DX-ing and DX-peditions: An amateur radio operator's main hobby is to make contact with as many stations as possible from as many parts of the world as possible. DX stands for Distant Stations. The DX-ing usually is followed with the QSO. (a Q code., see below) which means "a conversation".

DX-peditions are different in the sense that they are expeditions organized / planned solely for the purpose of making contacts with some special or rare stations and regions. Some people travel long distance just to make contact with some unrepresented region or place.

Radio Frequency scanners available now a days form the tool of great use in these attempts. The radio scanner scans for signals until a strong signal is found and so on.

QSL cards: The Q code is a standardized collection of three-letter message encodings, all starting with the letter "Q", initially developed for commercial radiotelegraph communication, and later adopted by other radio services, especially amateur radio. In today's audio signal transmission age, the Q codes are not essential. but still in use and are viewed as a sort of tradition.

As a part of DX-ing and DX-peditions the QSL card or the proof of contact card is shared. QSL is one such Q-code that means "I acknowledge receipt". The common practice was that the ones who made contact at a particular frequency exchange a QSL card in the mail to confirm their contact and conversations. These QSL cards can be used as a proof of their making contact and amateur operators who make contact with a certain number of other amateur radio operators in a specified time is awarded. Moreover, they are distinguished and honored since they are deemed to be efficient amateur radio operators.

Remote region contacting: Some countries have less amateur radio operators, and making contact with these is considered special. So, when a radio amateur from these regions makes contact, other ham operators flock to make communication with this / these hams. Making contact with these less represented places has its awards and special considerations in the award programs.

Hamfests: Social events for the ham families and friends. It's something akin to the family oriented social fests where there are sales, exchanges, meetings and fun. Similarly, the fest is filled with selling and exchanging hams, meeting real life ham friends and fun events for a day or sometimes over few days.

Discussion groups and Nets: Ham operators form a discussion group based on common interests other than ham or it can also be a ham related discussion group and they can form nets or networks.

If a radio hobbyist gets involved with all of these different activities, he or she is sure to never be bored. Look into some of them, and see if you would like to get involved.

The freezer section of the lab refrigerator has a lower temperature when compared to the main cooling unit of the refrigerator. This difference is very important especially in lab refrigerators where a large volume of expensive chemicals and biological material are stored. Temperature maintenance is of prime importance in all laboratories.

Sodium, a highly reactive element, is not available in free state. It is known to react violently with air. It is an alkali group of metals and profusely found in Earth and it is also found in minerals such as cryolite, zeolite and amphibole. Around 2.6 percent of the Earth's crust is made up of sodium. It is also found by electrolysis of dry fused sodium chloride.

Fungi are the member of eukaryotic organisms. They can be found everywhere and are omnipresent. In a recent study, fungi were declared to be closely related to animals rather than plants and for this reason they have been put in a separate group, i.e. different from plants, animals and microbes. Mycology is the branch of biology which deals the study of fungi.

Do you want to do a chemistry project which interests as well as enhances the knowledge of your kid about the subject? If so, then here are some top chemistry projects for kids that will not only enhance their knowledge, but also keep them entertained and busy.

Try something mysterious and let everyone get a surprise with your creativity and knowledge. Use invisible ink to write some secret message and hand it to the person the message is meant for. Use a toothpick as pen and saliva or lemon juice as ink. Even plain water can also be used.

Phosphoric acid or orthophosphoric acid is a mineral acid which is broadly known for its uses. This acid is made up of three hydrogen atoms, one phosphorus atom and four oxygen atoms. The chemical formula of phosphoric acid is H3PO4.

John Dalton was an English chemist, physicist and meteorologist. He was the first man whose proposed atomic theory was accepted. Dalton is also known as discoverer of color blindness. In the research, on the properties of atmosphere and gases in 1803, he discovered about atoms and their weights. It was published in 1805.

The chemical symbol of tin is Sn, which is derived from the Latin name Stannum. It has 50 protons and 50 electrons with an atomic number 50. It is a gray silver metal and generally used in wires and compressed to make sheets.

Soap is made up of sodium or potassium salts of fatty acids which are obtained from the reaction of oils or fats with an alkali at 80 to 100 degree Celsius. This process is referred to as saponification. Soap consists of carboxylate head and hydrocarbon tail.
