IW3SGT and Radio


I am SWL since 1996, but my interest in the radio began much more before, when after the purchase of the first RTX in the Citizen Band. I started the radio activity with the call sign of CB PIPPO. 

In the 1997 I started a ham activity with IW3SGT callsign. At this date only 50MHz and higher frequencies are avaiable for "IW" license. In the 2005, after the finish of the Morse code exam for Italian ham, all "IW" license can work below 50MHz band :-)

Most of my activity is in digital modes and I like to explore the LF and VLF frequencies.
