VA7XB: listings comments

The popularity of 80 m foxhunts is increasing due to the better directional characteristics (with less reflections) of 80m versus 2 m

To Use the RX80M: Determine the general direction of the fox with the RX turned broadside while pressing the button, then home in precisely on the null with RX turned sideways.  An instructional video describing this technique can be seen at
