• 20 thru 10 Meter Fan Dipole - The 20 thru 10 meter dipole is constructed from stranded insulated wire available in most hardware stores. The feedpoint uses an 8 inch long section of 2 inch diameter PVC pipe. A section of wire joins the elements at either side of the feedpoint to avoid the inductance of square knots used on lower frequencies.

• PSELab freeware - PSELab is a freeware Windows application useful to estimate power spectrum and short-time spectral distribution of signals. The application uses periodogram, least squares Prony, Burg, covariance, MUSIC and some other methods. To estimate short-time spectral distribution, the application uses short Time Fourier transform, pseudo-Wigner-Ville transform, least squares Prony, Burg, covariance, MUSIC and some other methods.
