Dear Thomas and all friends of SWLing Post,<\/strong><\/p>\n

I’m Giuseppe Morl\u00e8 iz0gzw from central Italy on the Tyrrhenian Sea, Formia.<\/strong><\/p>\n

A few days ago at a fair for radio amateurs in Latina, I bought an excellent very large variable capacitor–those of ancient military radios–and I found a splendid antique knob with a fantastic gear ratio.<\/b><\/p>\n

I called this VariabilOne<\/em> and it consists of two sections of 250pf each. It’s <\/strong>very portable and can be applied to any loop with crocodile clips.<\/strong><\/p>\n

I built another cross loop made up of 2 turns the internal loop, 35 cm. and only one turn for the external loop, 40 cm.<\/strong><\/p>\n

I can tune frequencies from 3.500 to 20.0 MHz. The crossed loop is strongly directive given the two loops that work together being joined on their ends.<\/strong><\/p>\n

I have made some demonstration videos and it is a pleasure for me to share them for our entire community (see below).<\/strong><\/p>\n

Thanks to you and I wish you all the best for you and your family.<\/strong>
\nGreetings to all.<\/strong>
