MAKE NATURE YOUR SHACK

World Wide Flora and Fauna in Amateur Radio

The 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.

The "DX Code of Conduct"

Operators are urged to support it:

* I will listen, and listen, and then listen again before calling. *
* I will only call if I can copy the DX station properly. *
* I will not trust the DX cluster and will be sure of the DX station's call sign before calling. *
* I will not interfere with the DX station nor anyone calling. *
* I will never tune up on the DX frequency or in the QS X slot. *
* I will wait for the DX station to end a contact before I call. *
* I will always send my full call sign. *
* I will call and then listen for a reasonable interval. I will not call continuously. *
* I will not transmit when the DX operator calls another call sign, not mine. *
* I will not transmit when the DX operator queries a call sign not like mine. *
* I will not transmit when the DX station requests geographic areas other than mine. *
* When the DX operator calls me, I will not repeat my call sign unless I think he has copied it incorrectly. *
* I will be thankful if and when I do make a contact. *
* I will respect my fellow radio amateurs and conduct myself so as to earn their respect *

TROPOSPHERIC DUCTING FORECAST

Tropospheric (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.
