The club would like to thank everyone who helped getting this repeater up specially Rocco (WU2M) for fixing and configuring the repeater and Jim (KC2JJQ) for providing the location for this repeater.

Near-Real-Time F2-Layer Critical Frequency Map

Ray (NM2O) has provided a link to the “Near-Real-Time F2-Layer Critical Frequency Map” website. The website shows the Critical Frequency. This information supplements the band conditions, flux, K, etc. graph to the left.

The definition of Critical Frequency is: The highest frequency that is returned when a signal is sent straight up. To work in close on HF, you need to be below the critical frequency.

The Space Weather site generates a new plot every 10 minutes or so. The plot takes into account the solar flux, the K index, the time of day and the date.
