Dear Thomas and all friends of SWLing Post,
I’m Giuseppe Morlè iz0gzw from central Italy on the Tyrrhenian Sea, Formia.
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.
I called this VariabilOne and it consists of two sections of 250pf each. It’s very portable and can be applied to any loop with crocodile clips.
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.
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.
I have made some demonstration videos and it is a pleasure for me to share them for our entire community (see below).
Thanks to you and I wish you all the best for you and your family.
Greetings to all.
73. Giuseppe iz0gzw.
Giuseppe, thank you once again for sharing your brilliant homemade antenna projects with us. I absolutely love that monster variable cap and tuning whee! What a thing of beauty–and obviously your loop is very effective.
Thank you as always, Giuseppe!
