The Q-code was developed and instituted in 1912 in order to facilitate communication between maritime radio operators of different nationalities. It is for this reason that the Q-prefix has been excluded from call-signs.
Shortwave Radio Listening Hobbits or DXers direct their "QSL" request (Can you verify transmission?) to radio stations around the world that they happened to have monitored. "D" in DX is for distance and the "X" refers to the unknown. DXers are hobbyists who enjoy DXing or trying to pick up radio stations from a distance.
These reception reports are valuable to radio stations in that they assist in evaluating transmission signal strength and quality. Radio Stations usually reply by mailing a "QSL Card". The QSL Card acknowledges the receipt of the report and confirms the details of the transmission.
To make the best of changing propagation conditions Radio Free Asia rotates frequencies during different seasons to maintain the best possible coverage. As a shortwave broadcaster Reception Reports are an important factor to Radio Free Asia in the determining the best frequencies to use to reach our target audience.
Radio Free Asia (RFA) welcomes all reception reports not only from DXers but as well as from its' listening audience. This site represents the efforts of radio Free Asia's Technical Operations Division to automate and streamline the QSL process.
