Amateur Radio: Your Gateway to Wireless Communication

Amateur Radio: Your Gateway to Wireless Communication

World Amateur Radio Day is celebrated each year on April 18 in recognition of the anniversary of the founding of the IARU in Paris in 1925

At the IARU Administrative Council meeting in September 2013, the theme 'Amateur Radio: Your Gateway to Wireless Communication' was adopted by the Council for World Amateur Radio Day, Friday, April 18, 2014.

Amateur radio has truly entered the 21st Century. In less than 100 years amateur radio communications has evolved from crude spark-gap technology to digital signal processing and software-defined radios.
The amateur's HF choice between voice and CW has been expanded to a broad range of communication choices from television to spread spectrum.

Amateur digital communications has evolved. At the end of World War II until the early 1980's, radioteletype, also known as RTTY, was the only HF digital mode available to amateurs. In the 1980's, AMTOR made its debut along with the increased popularity and availability of personal computers. AMTOR was the first amateur digital communication mode to offer error-free text transmission.

From the early 1980's, the rate of change increased dramatically. Packet Radio emerged and for a period of time was the most popular form of amateur digital communication. As microprocessor technology became more sophisticated, there was a rise in modes such as Clover, PACTOR, and G-TOR that were capable of error-free exchanges under marginal band conditions. In the late 1990's, there was an invention that harnessed personal computer technology to create PSK31.

In the VHF-UHF frequency ranges, Packet Radio had less activity at the close of the century than it did in the 1980's and 1990's. However, Packet Radio was reborn as the popular Automatic Packet Reporting System (APRS) and traditional packet systems still exist to support public service activities with greatly enhanced functionality.

Thanks to individual amateurs, hams now enjoy digital meteor scatter contacts and even moonbounce on VHF and UHF frequencies with modest stations. An ordinary computer sound device and software that can be downloaded free from the internet is all that is needed.

The Japan Amateur Radio League developed the D-STAR digital voice and data standard and there has been significant amateur growth as amateurs establish D-STAR repeater networks on the VHF, UHF and microwave bands.

All of these development have inspired amateurs around the world to experiment in their own HF, VHF, UHF and microwave band digital communication.

Activities on the occasion of World Amateur Radio Day can be a great opportunity to spread the word about what the "hams" are doing in the 21st Century.

This year, April 18 is a weekday. However, that doesn't prevent the public activity from taking place on the weekend after April 18. The idea is to gain as much exposure and publicity for amateur radio as possible.

WARD 2014 is an opportunity for amateurs to give presentations about ham radio to such groups as civic organizations, charitable groups, etc. For example, Rotary Clubs and Lions Clubs are only two of many worldwide organizations who have weekly meetings and these organizations are always looking for interesting and informative programs to present to their membership. There are very few experienced hams who can't talk for 15 or 20 minutes about ham radio in a positive fashion. Don't make the talk too technical. Stress the fun aspects of ham radio and the opportunity to assist in times of disaster. Keep the presentation to about 20 minutes to allow time for questions.

Amateurs can also show their expertise in digital and wireless communications, to those in the community who have “wireless communication” interests, but haven’t considered the association with Amateur Radio.

While true Amateur is the gateway, but it seems to me modern technology passes ham radio by. How am I going to get excited over RTTY when a smart phone is 800 to 1900 times faster? I been a ham over 1 year and my beef is we should be look forward instead of living in the past.

 

You are free to exercise your Part 97.1b "proven ability to contribute to the advancement of the radio art" any time you're ready. Don't need to wait for the rest of us.

 

Well it is Hobby if you like your smart phone use it . don't like ham radio then why bring your bitching about the past on here .
why did you bother to get a ticket.

 

This is one of the greatest features of amateur radio. At least on UHF and above, you're allowed to do pretty much whatever you please. A group of us are experimenting with Digital Amateur Television (DATV) with the latest crop of low cost transmit capable SDR's from http://nuand.com, https://www.ettus.com/product/category/USRP-Bus-Series and http://greatscottgadgets.com/hackrf/

Here's a spectrum analyzer trace of a bladeRF SDR transmitting two simultaneous 64-QAM channels on 70cm. Each channel is 27 Mbps, so the aggregate it 54 Mbps. The center frequencies are 429 and 435 MHz, which corresponds to channels 58 and 59 on a cable ready TV.



Even better, it's all open source.

w6rz Bingo ! that's is what I want to see, innovation not how thinks are back in the old day or ______ are not real hams.
I start to get into the maker thing (I just do not care for movements).
