Load your RF guns and get ready for the hunt........

K5RWK member extraordinaire, Andrew / KE5GDB, announces there will be two fox hunts this weekend, one in the Richardson area, and one in the SE quadrant of Denton County.

This will be the maiden voyage of his Pi-powered "Fox in a Box." For those unaware of foxhunting, amateur radio operators will hide a transmitter ("the fox"), and participants are to use radio direction finding techniques to find the fox. The goal is to simulate sources of interference, and practice finding the art of finding the interference. The closest thing he can liken it to is Geocaching with a compass instead of a GPS.

This Friday, Andrew will be placing the fox at about 11:00AM. It will operate on 144.5MHz, with a transmit power of 5 watts. It run until 3:00PM or until the batteries are dead. The suggested starting location is the Richardson EOC.

On Sunday, he will have the fox placed by 10:00AM in Southeast Denton County. This will also be on 144.5MHz, but have a transmit power of 35 watts. For first time fox hunters, Andrew will be hosting a brief crash course in radio direction finding. We will discuss the use of the body-nulling technique for handheld users, and I will also demonstrate how a directional antenna and attenuator can make the process even easier. He will follow up with more details about the crash course and suggested starting location when we've decided where to place the fox. The transmission pattern will be a 10-15 second audio clip, followed by a 45 second dead period.

Thanks to Andrew for the great fox hunt opportunity.

The K5UTD ARC will be installing equipment on the 300’ tower on the UT Dallas campus.

The primary mission is to move our 145.430 repeater antenna to the top of the tower. We are currently side-mounted, and have a “cone of shame” due south of the tower as an artifact of being side-mounted on the north leg. The current setup yields a cardioid-like pattern, as if a yagi were pointed at McKinney.

The secondary mission is the installation of 2.4GHz mesh equipment. The public facing radios are Ubiquiti Rockets with sector antennas. There will be 3 rockets mounted with 120 degree sectors, giving an effective coverage pattern of 360 degrees. These radios will be running AREDN. 5.8GHz radios will also be installed to provide internet to other area repeater sites and mesh installations.

The climb is scheduled for June 14th.
