RST code

The RST system used to assess the received radio broadcasts, while the value of T in particular by telegraphic ( Morse code ) radio communications, the RS values ​​for telephony shipments. Here, the readability ( R: readability ), the signal strength ( S: signal strength ) and the tone (T: tone ) evaluated the signal with digits.

Where:

R - of course

S - signal strength

The distance between the individual S-units from each other is 6 dB.

T - sound ( sound quality)

The value of T is judged in Telegrafiebetrieb.

Rare Annex a supplement is used to report by a slash:

The code X was mainly used in the early years of wireless technology, today almost all Telegrafiesendungen X.

While the course is the overall impression of the received signal, the signal strength of the transmission power depends on and the sound quality from the transmitter and the transmission path.

The RST system has been used since the 1930s by many radio services and is still used today, especially in the amateur radio service application.

For the assessment of radio transmissions ( Fonie ) the RS system is along the same lines used in which the assessment of sound quality does not matter. For the assessment of digitally coded signals ( radio telex, data transmission ), the RSQ system is used.

For the assessment of releases of radio transmitters ( shortwave broadcast ) the extensive SINPO system is used.
