Abstract :
Microwave CW transmissions from the French coast near Le Havre are being monitored at Portsmouth along a 155 km path. Preliminary observations indicate that the troposcatter levels of about -117 dBm agree with conventional calculations. However ducting has been seen to persist for long periods, with signal levels exceeding the free space value of -48 dBm by several decibels. On other occasions enhancements of several tens of decibels have been associated with warm and cold fronts and with heavy rain
