Record #170583:

Prediction of optimum traffic frequencies for northern latitudes / Canada. Defence Research Board.

Title: Prediction of optimum traffic frequencies for northern latitudes / Canada. Defence Research Board.
Author (corporate): Canada.
Date: 1954.
Publisher: Ottawa: Defence Research Board
Abstract: Manual for predicting optimum traffic frequencies for high frequency communication circuits in Northern Hemisphere for any hour, month, year. Two volumes cover periods January-June and July-December. System used is designed specially for high latitudes, i.e., greater than 35°N, taking particular account of distorting influence of auroral zone. System is also permanent, requiring only monthly forecasted ionospheric index.
