OK0EU is short-wave QRP beacon net set up by the OK QRP Club and supported by the Institute of Atmospheric Physics of the Academy of Sciences of the Czech Republic (UFA).

The output power 1 W and the dipole antenna of each transmitter simulate average working conditions of the QRP radio station. You can use the beacon for your RIG calibration, stability measurement, narrow band receiving experiments, etc.

The frequency of each beacon is set precisely and derived from the high stability 10 MHz normal with 2·10-10 short time stability. On 3.5 MHz, five transmitters with 4 Hz separation are running for multipoint measurement. The call sign is sent 40 Hz up to identify ionospheric echoes.

The scientific aim of the project is to study fine changes in ionosphere caused by the infrasound effects.
