In amateur radio, we use a number of abbreviations which begin with the letter Q as shorthands, particularly when using Morse cod
e. If someone sends QRS, it means that they wo
uld like you to send Morse code slower. QRSS has been taken to mean Morse code that is sent very slowly: typical is QRSS3, in which each "dit" in Morse code takes three seconds (this resu
lts in about 0.4 WPM). This kind of operation is slow, but can be useful in communicating at very low power levels over long distances. This website is dedicated to archiving information about this kind of radio operation. It isn't limited to just Morse, but will include information about other slow modes of operation that you might find on the amateur bands. |
