Spektrum DX6i six-channel spread spectrum computerized aircraft radio which may be used for both helicopters and fixed-wing models. Spektrum is a brand of radio control systems designed for use with hobby radio-controlled cars and aircraft. Spektrum is a division of Horizon Hobby.
[24] [25] [26] Introduced in the year 2000, the radio was known for its "all-in-one" functionality. It can transmit on all amateur radio bands between 160 meters and 70 centimeters, with the exception of the 1.25 meters band, and the "X" model also has built-in 23 centimeters band capability option. Kenwood discontinued production of the TS ...
For many years, amateur radio operators were required by international agreement to demonstrate Morse code proficiency in order to use frequencies below 30 MHz. In 2003 the World radiocommunications conference (WRC) met in Geneva, Switzerland, and voted to allow member countries of the International Telecommunication Union to eliminate Morse ...
The first radio transmitters could not transmit audio (sound) like modern AM and FM transmitters, and instead transmitted information by radiotelegraphy; the transmitter was turned on and off rapidly using a switch called a telegraph key, creating different length pulses of radio waves ("dots" and "dashes") which spelled out text messages in Morse code.
Early experiment demonstrating refraction of microwaves by a paraffin lens by John Ambrose Fleming in 1897. After their discovery many scientists and inventors experimented with transmitting and detecting "Hertzian waves" (it would take almost 20 years for the term "radio" to be universally adopted for this type of electromagnetic radiation).

Voyager 1 relays messages to NASA’s mission control team after losing contact due to a technical issue. The aging spacecraft is relying on an old radio transmitter.
A spark-gap transmitter for generating radio frequency electromagnetic waves. Such devices served as the transmitters for most early wireless systems. 24 December 1906: Reginald Fessenden uses an Alexanderson alternator and rotary spark-gap transmitter to make the first radio audio broadcast, from Brant Rock, Massachusetts.
In the 1970s, the Swan 500 was upgraded again and became the model 700 and 750, and underwent a styling change in later versions after the merge with Cubic. Swan also designed a matched, separate receiver and transmitter pair, the 600R and 600T, which together offered better performance, higher output power and many more features than the ...
