This is aimed at new HS4 users like myself.

When i first started using HS4 I couldn't see any activity on the standard display and thought HS4 was a waste of time and effort compared to HS3, having read about the waterfall i decided to purchase it and i am glad i did i started to see plenty of activity which meant i could start using the rotating fishbone antenna that comes free with HS4 (there are two one fixed one rotating) to get a better reception, after installing it making QSO's was a doddle, worth every penny.

This "Waterfall" display gives you a visual overview of the band. As it scrolls slowly down you get a kind of "memory" of the signals and you can get quickly determine where there is activity. Also very faint signals that you would have problems hearing also give a print.
