Over the years, the original meaning completely disappeared. Amateurs, possibly unfamiliar with the real meaning of the term, picked it up and applied it to themselves.
HAM RADIO RTTY EQUIPMENT CODE
Two amateurs, working each other across town, could effectively jam all the other operations in the area.Īnd while there are several theories on this, it is said that the use of the term “ham” to describe those early amateur radio operators was a derogatory term coined by frustrated commercial operators, a short version of “ham fisted,” meaning the operator couldn’t send Morse code very well.
HAM RADIO RTTY EQUIPMENT PROFESSIONAL
To the dismay of professional telegraphers, many of the amateur stations were very powerful. That meant that government stations, ships, coastal stations and an increasingly numerous group of amateur operators all competed for time and signal supremacy in each other's receivers. Instead of having equipment that used vacuum tubes (which were introduced after World War I) and later transistors to transmit on specific frequencies, in those early days, spark gap messages soaked up all of the radio broadcast band width. They brought with them their language (Morse code) and much of the tradition of their older profession.

In fact, the first “wireless” radio operators were land-line telegraphers who left their offices to go to sea or to man coastal stations. Today, Amateur Radio RTTY uses soundcard-equipped computers and dedicated RTTY software.įor more great information visit the following links:ġ.843-2.000 SSB, SSTV and other wideband modesģ.585-3.600 Automatically controlled data stationsħ.100-7.105 Automatically controlled data stationsġ0.140-10.150 Automatically controlled data stationsġ4.095-14.0995 Automatically controlled data stationsġ4.1005-14.112 Automatically controlled data stationsġ8.105-18.110 Automatically controlled data stationsĢ1.090-21.100 Automatically controlled data stationsĢ4.925-24.930 Automatically controlled data stationsĢ8.120-28.189 Automatically controlled data stationsĢ8.385 QRP SSB calling frequency (Technician class voice frequencies between 28.300 and 28.The concept of sending telegraph messages without connecting wires was around for some 50 years before Italian inventor Guglielmo Marconi created a practical system of “wireless telegraphy,” one using a relatively simple oscillator composed of a spark-producing radio transmitter coupled with a wire placed above ground, a receiver, and a telegraph key to transmit long and short pulses corresponding to the dots and dashes of the Morse code (developed in 1836) and a telegraph register to record the dots and dashes on a roll of paper tape.

RTTY was originally designed for use with mechanical teleprinters, predating personal computers by several decades. It is also the most popular mode for worldwide digital contests and remains in common use among DXers and DXpeditions. While RTTY does not support the features of newer computer-based data modes, it is well suited for keyboard to-keyboard chats with other stations. Radioteletype (RTTY - often pronounced “Ritty” ) is a venerable data communication mode that remains in wide use today among radio amateurs.
