We will be discussing plans for the JOTA event on the afternoon of Saturday 17th October.

We intend to put up some ropes over some trees on Saturday 10th October in preparation for setting up a number of stations for JOTA.  Possiblly three wire antennas strung between the trees will be required plus some HF Transceivers so that three bands can be used.

Propagation Help

At the recent General Meeting, a member sought assistance in the method of determining HF propagation conditions on particular paths.

This is a complex subject, but a simple method is to to be found on this site.

This is a web based version of the VOACAP program originally devised by the international broadcaster Voice of America.

Full instructions for use may be found here but, for normal use, it is only necessary to "drag and drop" the red symbol on the map (the transmitter QTH) and the blue symbol (the receiver location). Set the transmitter power and select antennas from the lists. Select the modulation type.

Current sun spot number is updated automatically in that program but for completeness it, and various other indices are tabulated below.
