Topband: Beverage F/B using oscillator

[Greg - ZL3IX]

Hi Ashraf,

The rule of thumb I use is 2D^2 /lambda, where D is the largest 
dimension of the antenna. So if your Bev is 320m long you need to be 
over a km away. If only 160m long you need to be 300 m away.

73, and I hope to work you one of these days at my SR.
