Hi!

 

In a few months, my club is going to do some fox hunting activities.  My
question here relates not so much to making the "antenna" itself per say,
but rather to making an audible tone direction indicator.  I think this
thing is called a "V C O?"  Basically, the V C O causes the pitch of a tone
to change as the direction finding antenna is pointed towards the fox.

 

A very techy friend of mine in the club is going to build this contraption
for me, including the antenna itself.  He has some ideas.  However, I wonder
what others here on our list have done?
