By means of a bistatic FM‐CW sounding system (transmitter‐receiver distance 565 km in central Europe), group‐delay and Doppler records at several fixed frequencies (about 4–8 MHz) were made. The daytime records show medium‐scale travelling ionospheric disturbances (TIDs). Ray‐tracing studies are presented which exhibit the influence of some ionosphere and TID parameters on the shape of the group‐path traces. Quantitative comparison between observed and calculated traces shows agreement.
