MAKE NATURE YOUR SHACKWorld Wide Flora and Fauna in Amateur RadioThe WWFF program wants to draw attention to the importance of protecting nature, flora and fauna. In this spirit amateur radio operators set up and operate their radio stations from designated nature parks and protected nature areas – generating attention for these areas whilst giving the ham radio community an interesting activity to contact. WWFF is an international and non-commercial program run by the coordinators of a large number of national Flora and Fauna programs.WWFF:- http://wwff.co/about/ |

TROPOSPHERIC DUCTING FORECASTTropospheric (a.k.a. "Tropo") DX modes are defined by the mechanics behind them. A Tropo DX mode is any condition that scatters, reflects or refracts signals in the Troposphere allowing long distance reception (and hence interference) to occur in the VHF, UHF and/or microwave radio bands. Refraction occurs when the normal Index of Refraction has been altered. Vertical boundaries between different types of airmasses usually cause this..where a temperature inversion (warm air over cooler air) exists. This causes signal enhancement. When the vertical boundary becomes especially sharp, the amount of refraction becomes so severe that signals extend a great distance as though caught in a duct...thus the reference to tropospheric ducting.Propagation:- http://www.dxinfocentre.com/ |
