Amateur Radio

Amateur Radio And Admiral Byrd
The use of radio on dangerous missions of exploration is not just a safety issue. Explorers learned quickly that regular news reports created public interest in their expedition making it easier to raise funds for the future. This had been illustrated by one of the early expeditions to the Arctic, the Macmillan expedition.
In the mid 20's with the great depression looming, raising money for Arctic exploration wasn't easy, but the public imagination was captured when transmissions from the Macmillan expedition were received, not by a carefully setup ground station, but by Arthur Collins, a 15 year old radio amateur from Iowa who then relayed their information to Washington.
One participant in the McMillan expedition was Richard E Byrd who claimed (some have disputed his account) to have been one of first men to fly over the North Pole.
In 1928 Byrd set off on an expedition to the Antarctic and in 1929 became one of the first men to fly over the South Pole. His expedition was the first under the American flag since 1840 and was recognizably modern, making use of planes, cameras and snow mobiles as well as the all important radio communications equipment.
News of his polar flight and the discovery of Marie Byrd land (which he named after his wife) stimulated American interest; his regular (Morse code) broadcasts also made a genuine difference to Byrd's fund raising for his next expedition. Over $150,000 was raised, most in the form of gifts from thousands of donors all providing small amounts.
Byrd, a descendant of John Rolfe and Pocahontas, had first hand knowledge of the power of publicity so he sold newspaper and photographic rights as well as advertising on his newest initiative; weekly voice broadcasts broadcasts from 'Little America' the base he had established on the first expedition. His ability to organize was remarkable, his first two expeditions to Antarctica being completely funded and organized by him with no official government involvement.
The first voices from Antarctica were heard on 1st February 1934 and thereafter a weekly broadcast was sent out on the CBS network. On March 28th the final tractors left the site of the expedition's advanced base where the plan called for Admiral Byrd to remain alone throughout the Antarctic winter. The sun set on April 19th leaving the Admiral alone in the cold and the dark, the rest of his team over 123 deadly miles away, but securely connected to him by radio.
His schedule called for meteorological observations every day and three radio calls a week to Little America. Four months of darkness also provided an ideal opportunity for observations of the aurora, but things did not go well. The hut at advanced base was not properly ventilated and over time Byrd was affected by carbon-monoxide poisoning. He collapsed during the radio call of May 31st and remained extremely ill for more than a month. His radio transmissions deteriorated and became 'unusual' alerting Little America to the situation.
Attempts at rescue at the height of the Antarctic winter failed at first, however the doctor and two others finally reached advanced base on August 10th, by which time Byrd had been ill and alone for more than four months. He was too weak for the journey back to Little America and so his rescuers remained at Advanced camp until October 12th when the Antarctic Spring made it possible to fly the Admiral to safety.
It is likely that without rescue Admiral Byrd would have died at advanced camp. Despite the fact that his health never fully recovered from the ordeal, and his self-esteem took a severe blow he owed his life, as well as his now heroic reputation to radio.
How does the FCC find out and pinpoint the exact source of amateur radio violations?
I was browsing the FCC amateur radio site, on a page that references warning notices sent to people for violations using ham and CB radio equipment.
The site is: http://www.fcc.gov/eb/AmateurActions/Welcome.html
How do they actually track down who’s committing the violations, especially if they don’t have an amateur license, therefore no address on record? How long does it take for them to find out who’s responsible?
Amateur radio?
I’d like details on amatuer radio…
for eg
1)what exactly is it used for?
2)What is its range of use?
3)who can listen to it?
4)What exactly do you speak on it?
5)Is it like being an rj??
6)Do you need to buy a different radio then your regular one to catch that frequency?
7)is it available in india?
Or just post links to details of amateur radio pppllleaassssssseeeeee
Its for my college seminar..
Can you thnk of any other telecommunication device i can speak on??
Emma you are a life saver.. muah
Any radio transmission can easily be tracked simply by noting the strength of the signal from locations.
1900s technology.
What is the maximum Amateur Radio/Ham Radio transmission wattage allowed for 10 and 12 meter bands?
For example, can someone use a 10 kW transmitter if a valid license is held for Amateur Radio?
What is the equipment required for an amateur radio? Also, how is it different from a “normal” radio?
Hi!
I’m working on a project on amateur radios. Please tell me about the equipment required(in very simple terms, nothing too technical, for I’m a novice). Please explain terms wherever necessary.
Also, how is an amateur radio different from a “normal” radio?
Thanks!
P.S. Thank you for not citing, or lifting info from Wikipedia. Nothing in there.
Kindly be more specific about the equipment, i.e. please tell about the microphone, the gadgets, basically required.
Thanks!
How do the Police catch a criminal using an *unlicensed* amateur radio to transmit threats?
I recently received threats and harassment during telephone conversations from an unknown third party using an amateur radio. How do the police catch him? Is it possible if he doesn’t have a license?
They don’t care.
They will tell you they’re looking into it and then get back to you in 10 years time and tell you there was no evidence.
Assuming you are in the US, if operating on 10m as a Novice or Technician, you are limited to 200w. Otherwise you can work 1.5kw on 10m and 12m. Although 1.5kw is allowed, you are to use the minimum power needed to work a station. 10kw is WAY out of the ballpark.
Ham radio is for anyone who likes to communicate with others via wireless technology. It is also for anyone who enjoys experimentation. Licensed amateur radio operators communicate with each other in nearby places, across the country, around the world or even with astronauts in outer space!

Hope these links help you. Goodluck!
Let’s start with “Normal Radio”. Broadcast radio is usually run to communicate with a large audience. It usually is one way only, i.e. it is “Broadcast”. The AM radio broadcasts on a special part of the radio spectrum between 550 kHz and 1500 kHz. FM broadcasts on the FM band which is between 88 MHz to 108 MHz. Additional broadcast bands exist (called Short Wave, mainly AM) between 5.8 MHz to 26.1 MHz. Television is also Broadcast usually in the VHF bands.
Amateur Radio on the other hand is almost never Broadcast. It is designed for point to point Communication and is usually between two parties. It uses spectrum in several bands, such as:
HF. These bands have long distance capability due to ionospheric reflection.
10 meters – 28–29.7 MHz
12 meters – 24.89–24.99 MHz
15 meters – 21–21.45 MHz
17 meters – 18.068–18.168 MHz
20 meters – 14.0–14.35 MHz
30 meters – 10.1–10.15 MHz
40 meters – 7.0–7.3 MHz
60 meters – 5 MHz region
80 meters – 3500–4000 kHz
Medium frequency
160 meters – 1800–2000 kHz
Low frequency
136 kHz – 135 – 137 kHz
Also used are various VHF, UHF and SHF bands. These bands are useful but are limited by only being line of sight. They are used for various modes such as Television, EME (Earth, Moon, Earth), Satellite, etc.
In order to be able to use these bands, an operator needs various things. Top of the list is a License, provided after the prospective amateur satisfies the Government requirements, which usually consists of a test and paying money. He or she will also need the specialized equipment to be able to transmit and receive on those bands.
