Old fashion Skip

Tropospheric ducting is radio propagation that tends to happen during periods of stable weather. In this propagation method, when the signal encounters a rise in temperature known as a temperature inversion, the higher refractive index of the atmosphere will cause a radio signal to be bent. Tropospheric ducting affects all frequencies, and signals. In other words good old fashion radio skip.

there is a good site that tells you when skip may occur http://home.cogeco.ca/~dxinfo/tropo.html

I can stop scratching my head. As I look at the temperature and humidity I believe are indicators of a temperature inversion. The local traffic reporter in his plane always says there is a temperature inversion today. From now on I will listen to the traffic reporter rather than the weather man.

What does this tell me. Well it looks like I have to manually set each stationary mesh node. What I setting is to block any nodes that are not in the area of the radio signal. The reason for doing this is to illuminate the skip. Now my experience with skip was that I was experiencing very good throughput, but the signal did not last very long.

To block all the radio signal seems impossible, so my strategy is to block any signal that is skipping. It still a manual approach but at least I can stop scratching my head!
