Tropospheric forward scatter appears to be useful for transmissions over distances up to 600 miles, such as air-to-ground communication between a plane in flight and its control tower, at frequencies from 100 to at least 10 000 megacycles per second.  3, record 1, English, - tropospheric%20forward%20scatter

As troposcatter loss increases with the scatter angle[,] you will obviously want to have as small [a] scatter angle as possible. This means that the two radiation angles should be kept as small as ever possible since every degree costs 9-12 dB [decibels]. If there is a mountain in the direction of the other station[,] you must have a high radiation angle to shoot over the mountain, and this will cost you many dB [decibels] in signal strength.  2, record 2, English, - tropospheric%20scatter%20loss

Pour ce faire, le programme [...] calcule à la fois l'affaiblissement de diffraction et l'affaiblissement par diffusion troposphérique entre deux points. La valeur la plus grande des deux types d'affaiblissement est ensuite ajoutée à la valeur de l'affaiblissement en espace libre.  1, record 2, French, - affaiblissement%20par%20diffusion%20troposph%C3%A9rique

Where a fixed service using tropospheric scatter operates in the bands listed in the first column and there is insufficient frequency separation, there must be sufficient angular separation between the direction to the space station and the direction of maximum radiation of the antenna of the receiving station of the fixed service using tropospheric scatter, in order to ensure that the interference power at the receiver input of the fixed-service station does not exceed-168 dBW in any 4 kHz band.  1, record 3, English, - sufficient%20angular%20separation

Lorsque le service fixe utilisant les techniques de diffusion troposphérique fonctionne dans les bandes énumérées dans la première colonne et que la séparation de fréquence est insuffisante, il faut prévoir une séparation angulaire suffisante entre la direction de la station spatiale et celle du rayonnement maximal de l'antenne de la station réceptrice du service fixe utilisant les techniques de diffusion troposphérique, afin que la puissance de brouillage à l'entrée du récepteur de la station du service fixe ne dépasse pas -168 dBW dans une bande quelconque large de 4 kHz.  1, record 3, French, - s%C3%A9paration%20angulaire%20suffisante
