The World of CBs, Hams, and Shortwave Radios

Radio has come a long way from its inception in the late 1800s. The use of radio waves developed by scientists and researchers, have scrambled to come up to the top. Radios have caught the public’s interest thus resulting in various uses of the sine waves that are modulated by frequencies to produce signals in what we now know as CBs, hams, and shortwave radios.

With our knowledge of radios and how they function, we will now investigate other uses of radios aside from the fact that it is a device that transmits music, speech and image through waves. We may also want to find what accessories CBs, shortwave and hams have that we may need in order to enjoy their functionality.

1. Shortwave radios

Shortwave listening is a hobby with a lot of people participating. To enjoy this kind of radio, we need a portable shortwave antenna specially made for travel or home, or an outdoor antenna kit; headphones perfect for scanner or shortwave listening specially in noisy places; external speakers that adds depth to multimedia programs and games; speakers for surround sounds, and listening guides to help users deal with FM reception in some areas.

Subscribers can glean more info from the NASWA (North American Shortwave Association) and the DXing.com (Distant Station Listening).

2. Ham or amateur radios

Amateur radio encompasses all aspects of radio communications. It first started in the 1900s and developed along with other radio technology in the 20th century and is now largely used in the 21st century. It works through satellites, microwave links, bouncing signals off the moon, and just simple radio contacts.

There is a one-of-a-kind combination of fun, public service, and ‘easy listening quality’ that sets aside amateur radio interesting from the rest. Hams get involved for many reasons but they all have the basic knowledge of radio technology and its operating principles, and pass an examination for the FCC license to operate on radio frequencies known as the Amateur bands.

There is always the appeal of participating in communications around the world, enjoy using the Amateur Radio’s digital communications opportunities, join DXing contest, where the goal is to find how many participants a user can locate in the world. But mostly, a lot of hams find it interesting to hook up with other participants to develop friendships.

3. CBs or citizen’s band

Citizen’s band is a service that does not need any license. This public two-way personal radio service is of limited range. The operation of a citizen’s band radio is authorized under the Radio Communications Class License 2002 in Australia. However, in the US, as of December 8, 2006, it will no longer require a WT (Wireless Telegraphy) Act license.

4. The newest in radios

iFM combines FM tuning, recording, and boasts of remote control features for iPod usage. Users can now easily interchange between listening to their compilation of music to tuning into local FM stations’ radio programming. It is also a recording device, with a built in microphone to record voice, or change modes to capture live FM radio directly to the user’s iPod.

The iFM features are: digital audio scan with wraparound; band-switch function to swap between US, European, and Japanese FM bands; has a remote that goes from play to next song; a recorder that automatically saves to the iPod but limited to only the space or memory of the iPod; and price starts from US$49.00.

Whatever type of radio interests you - CB, shortwave or ham - there are lots of information you can find to get yourself absorbed in.
