Full wave methods and wave guide concepts are used to calculate the nighttime 17.8‐kHz radio fields along the 40°W parallel of longitude at 500‐km altitude. The fields are generated by the ground‐based transmitter at Cutler, Maine. The results are compared with data obtained by the Ogo 4 satellite and with results of Souza and Scarabucci, which were calculated using other methods. Wave guide leakage accounts for general features of measurements made in the northern geomagnetic hemisphere. Measurements made in the southern geomagnetic hemisphere suggest that those fields can be estimated by assuming lossless whistler mode propagation of wave guide leakage fields at the geomagnetic conjugate.
