Video of my shortwave radio Christmas present
Here is a short video clip that shows the shortwave radio kit that I built over Christmas. I tried both my vertical and horizontal antennas and both appeared to give similar results. Whilst tuning around the bands (12MHz to 18MHz) I received several foreign stations. Near the end of the video is a short audio clip. Rather annoyingly I was also picking-up some local interference. The signals appeared to be fading so were coming in via the sky wave, which is probably why my different polarized antennas gave a similar signal strength. I will try the radio under different weather conditions and different times of the day to see if the results change. There are several beacons within the receivers range so this would be a handy way of checking propagation.
