6 Elements Yagi Antenna on 50 MHz - This is a design based on the QuickYagi 4 software by WA7RAI with some changes for practical reasons. The beam uses 6.5 metres of standard 25mm square boom, 12mm diameter elements without tapers. The actual boom length used is 6.3 metres and all parts are readily available.

The NorthEast Wisconsin DX Association - The NorthEast Wisconsin DX Association (NEWDXA) was established in December 1993 by twenty-one amateurs from the region who shared an interest in DX'ing and Contesting. Those individuals came together because of this interest and the additional interests in communicating with others, maintaining high operating and technical standards, and their passion for DX'ing.

1200z Time Explained - Military time notation is based on 24-hour clock. A time of day is written in the form hhmm, where hh (0-23) stands for full hours that have passed since midnight, mm (00-59) is the number of minutes that have passed since the last full hour. To convert hours greater then 12 to 12-hour clock just subtract 12 from the given hours and that will give you the PM time
