The American Radio Relay League (ARRL) is the largest membership association of amateur radio enthusiasts in the USA. ARRL is a non-profit organization, and was founded in April 6, 1914 by Hiram Percy Maxim of Hartford, Connecticut. The ARRL represents the interests of amateur radio operators before federal regulatory bodies, provides technical advice and assistance to amateur radio enthusiasts, supports a number of educational programs and sponsors emergency communications service throughout the country. The ARRL has approximately 154,000 members. In addition to members in the US, the organization claims over 7,000 members in other countries. The ARRL publishes many books and a monthly membership journal called QST. The ARRL held its Centennial Convention in Hartford, Connecticut in July 2014.
The ARRL is the primary representative organization of amateur radio operators to the US government. It performs this function by lobbying the US Congress and the Federal Communications Commission. The ARRL is also the international secretariat of the International Amateur Radio Union, which performs a similar role internationally, advocating for amateur radio interests before the International Telecommunications Union and the World Administrative Radio Conferences.
Amateur radio (also called ham radio) describes the use of radio frequency spectra for purposes of non-commercial exchange of messages, wireless experimentation, self-training, private recreation and emergency communication. The term "amateur" is used to specify "a duly authorised person interested in radioelectric practice with a purely personal aim and without pecuniary interest;" (either direct monetary or other similar reward) and to differentiate it from commercial broadcasting, public safety (such as police and fire), or professional two-way radio services (such as maritime, aviation, taxis, etc.).
The amateur radio service (amateur service and amateur-satellite service) is established by the International Telecommunication Union (ITU) through the International Telecommunication Regulations. National governments regulate technical and operational characteristics of transmissions and issue individual stations licenses with an identifying call sign. Prospective amateur operators are tested for their understanding of key concepts in electronics and the host government's radio regulations. Radio amateurs use a variety of voice, text, image, and data communications modes and have access to frequency allocations throughout the RF spectrum to enable communication across a city, region, country, continent, the world, or even into space.
Radio is the use of radio waves is to carry information, such as sound, by systematically modulating some property of electromagnetic energy waves transmitted through space, such as their amplitude, frequency, phase, or pulse width. When radio waves strike an electrical conductor, the oscillating fields induce an alternating current in the conductor. The information in the waves can be extracted and transformed back into its original form.
Radio systems need a transmitter to modulate (change) some property of the energy produced to impress a signal on it, for example using amplitude modulation or angle modulation (which can be frequency modulation or phase modulation). Radio systems also need an antenna to convert electric currents into radio waves, and vice versa. An antenna can be used for both transmitting and receiving. The electrical resonance of tuned circuits in radios allow individual stations to be selected. The electromagnetic wave is intercepted by a tuned receiving antenna. A radio receiver receives its input from an antenna and converts it into a form usable for the consumer, such as sound, pictures, digital data, measurement values, navigational positions, etc. Radio frequencies occupy the range from a 3 kHz to 300 GHz, although commercially important uses of radio use only a small part of this spectrum.

Having some fun tuning around on a vintage radio on Straight Key Night! This is an ARRL ham radio sponsored event that takes place every year on New Year's Eve.
An Introduction to the ARRL Teacher's Institute on Wireless Technology. Part of ARRL's educational outreach to schools through our Education & Technology Program, The "TI" an expenses-paid professional development seminar, in locations through the U.S. The Teachers Institute has provided teachers at all grade levels with tools and strategies to introduce basic electronics, the science of radio, space technology and satellite communications, as well as weather science, introduction to micro-controllers and basic robotics in their classrooms. The curriculum is designed for motivated teachers and other school staff who want to learn more about wireless technology and bring that knowledge to their students. Visit http://www.arrl.org/ti for more information and enrollment instructions.
This video introduces steps to successfully complete the the Technician Class license for Ham Radio. The Technician Class license is the entry-level license for new ham radio operators. This video includes tip on studying, the differences between license classes, preparing for the test as well as what to bring, and what is required to successfully pass the exam the first time.

After 40 years of Membership in ARRL, many years renewing annually, some biannually and eventually a few years ago Life Membership I received a surprise the other day! A VERY NICE gesture from the American Radio Relay League sent me a 40 Year Anniversary Pin. It is a little small but it was a very nice gesture which was totally unexpected. Thank you ARRL for all you do and have done for Amateur Radio. It makes me want to become more active! I love Ham Radio and wish I had more time and ability to put up any antenna I want(live in neighborhood with HOA) but have some inventive ones which allow me to get on the air!

The ARRL has launched a survey of members asking about maybe asking the FCC for a new Entry Level License. This show brings together a Pundit Panel of Podcasters (aka Herding Cats) to kick the ideas around. If Gary KN4AQ thought he had a plan for the show (and he sort of did), it fell before the onslaught of Neal Rapp WB9VPG (HamTalkLive), Sterling Coffey N0SSC and Marty Sullaway KC1CWF (PhasingLine Podcast), and co-host David Goldenberg W0DHG. Many words... but probably still not the Last Word! The survey is here: http://www.arrl.org/license-1
[Dialogue from Daria Morgendorffer on MTV's "Daria":]
My advice is, stand firm for what you believe in
Until, and unless, logic and experience prove you wrong
Remember
[Ja Rule:]
Yeah, shhh
It was supposed to be you and I and the curtains closed
But somewhere along the lines we switched episodes
It's kinda like when Gina left Martin for New York
Speaking of New York, the city is so lost
Even with the Knicks lookin to make the playoffs
Spike is back on the court, and Jeter's still in the Bronx
Bloomberg got the city ready for seance
Go get your ouija boards out niggaz and pray on
You want "Drama"? Get your fuckin "Kay Slay" on
Still got the world on my shoulders, a nigga headstrong
About to go in; you can lock my body
Contract my mind, my thoughts keep escapin
Power of the pen it work provoc' like Basquiat
They fancy, 'cept I paint my pictures lyrically
But fancy enough, bitch foamin like a Swiss B
And we ain't talkin hoes, we talkin Euros and raw weed
[Chorus:]
Who do you believe in?
Is it money or the man upstairs? Is it power or prayer?
God bless the dead and fuck the world fast
What's progression if you never been through backlash
Nigga what do you believe in?
Cause my money's on me, myself and I, my team and this music
Y'all ain't gon' believe this
Maybe it's my fault, or maybe y'all just makin excuses
[Ja Rule:]
Who do you believe in?
Motherfucker the money is talkin to me and tellin me that it's lonely
In need of new friends, preferably Grants and Franklins
And the singles and the fives went to the bitches
Dubs is for wifin in the club, no mention
But you know who you are, nigga stop flinchin
Stop cuffin; you may not think that it's a bitch
But life's a hoe and everybody's been fuckin~!
See that's what I believe in
With n o logic, no need for experience
To fuck the world would be a lifetime achievement
You make it cum then e'rybody jump on the dick
Y'all niggaz full of shit, that's why you fuckin assholes
And never smell the shit stinkin 'til you get shitted on
Fuck 'em all, not for nothin
I ain't "Always On Time", too much ice in the vodka muh'fucker
