Giuseppe Demonstrates his homemade “Minimal Long-Distance Dipole”

Many thanks to SWLing Post contributor, Giuseppe Morlè (IZ0GZW), who shares the following:

Dear Thomas and Friends of the SWLing Post,

I’m Giuseppe Morlè from Formia, central Italy on the Tyrrhenian Sea.

This time I want to show you 2 QRP connections made with minimal antenna over long distance and very few watts of power…

The antenna is a simple dipole, 5 meters per arm, 1/4 wave for 20 meters, on a bnc / banana socket directly on the Icom 705. You’ll see that the ROS is really optimal.

I wanted to experience this very simple antenna, easy to prepare in this location surrounded by greenery, Monte Orlando Park in Gaeta on my favorite DX bench;
this location is at 120 meters above sea level and facing south / west following the long path. A suitable place for the extreme right made especially for a receiver like the Icom 705– fantastic modulation and without any kind of noise.

In the first video the contact with VK2GJC, Greg from Australia who struggles a little to listen to me but immediately understands my name. As you can hear Greg’s voice is without any imperfection even if his signal is not that high:

In the second video, another link with Australia, VK5AVB, Tony from Kangaroo Island.
Tony had a hard time understanding my name but with the help of Nicola, IU5EYV from Tuscany, in pure Ham Spirit, he finally managed to log me:

As you can see, even with very minimal antennas hoisted on nearby trees, not even high from the ground, you can listen and contact over long distances … that’s why I love this place so much!

Thanks to you all, a cordial greeting from Italy.

Many thanks, once again, Giuseppe for showing us just how much fun we can have by building our own antennas and hopping on the air with very little power. I must say: you certainly play radio in a beautiful part of the world! Thank you!

Giuseppe’s latest homemade ferrite antenna for MW and SW

Dear friends,

I’m Giuseppe Morlè from Formia, central Italy on the Tyrrhenian Sea.

I want to share with you my latest ferrite antenna for listening; it is composed of 3 ferrites of 20 cm each in a tube for electrical systems with 2 separate windings, one for medium waves and one for short waves, 40 turns for medium waves, 4 turns for short waves. I use a 750 pf variable to tune the 2 windings and a switch is used to eliminate a winding. Since there is only one variable, if you listen to the medium waves I interrupt the winding of the shorts.

On shortwaves it is preferable to place the system on an iron railing which, due to inductive effect, behaves like a really long wire antenna.

For the mediumwaves it is enough to bring the receiver close to the ferrites and also in this case, the induction will have its effect with an excellent increase in signal and modulation.

The range of this portable antenna is:

- - 520 to 1800 kHz
  - 3.500 to 18.000 MHz

Here’s a video from my Youtube channel where I explain how it works:

I had previously built a similar antenna but with 12 cm ferrites–very portable.

Thank you for your attention and I wish you good listening.

This is brilliant, Giuseppe! I love how you never stop building and experimenting with various antenna designs! Thank you for sharing this with us!

Giuseppe pairs his Kenwood R-1000 & Indoor Cross Loop Antenna

Dear Thomas and all friends,

This is Giuseppe Morlè, IZ0GZW, from Formia, central Italy on the Tyrrhenian Sea.

I went back to listening with my Kenwood R1000 and indoor homemade cross loops …this time a station in Kuwait, 9k2yd Younes on general call.

I used the 2 loops together and in the last part only the one in the East / West direction and I did not notice any changes. Very strong signals and good evening propagation at 18.00 utc today, 04 June 2022.

Note the absence of electrical noise; the S Meter remains at zero in the absence of modulation and signal.

I am always amazed at my indoor cross loops for the reception quality and they have become the main antenna of my Kenwood R1000.

Giuseppe I hope you enjoy the video
Greeting to all of you from central Italy.

Your cross loop antenna is an amazing QRM-fighter! Thank you for sharing this, Giuseppe. Most impressive and so good to see the R-1000 on the air.

How Giuseppe protects his Icom IC-705 during travels

Dear Thomas and Friends,

Giuseppe Morlè (IZ0GZW) here from Formia, central Italy.

This my latest video is about everything I have done to protect and transport my Icom IC-705.

I bought an aluminum case, light and very resistant with everything one needs inside to be able to use the IC-705.

- 2 power banks, one of which is solar-charged to be able to recharge the battery while in operation
- 2 wire antennas: a dipole type with BNC / banana socket with 10 meters of cable per arm and a 20 meter row, monopole, to be used in reception as you saw during the DXpedition to the Island of Ponza
- I also bought the Mydel protective “cage” with antenna attachment on the front and PVC protection of the display

Given the high cost of this little jewel, it is advisable to take all precautions for its safety during transport and use.

I hope I made you happy …
Thank you all,
73. Giuseppe Morlè iz0gzw.

This is great, Giuseppe! Like you, I’ve taken extra measures to protect my Icom IC-705 as well. Your kit looks comprehensive–I love the fact that pretty much everything you need is inside.

Thank you again. We always enjoy your posts from beautiful Italy. Ciao!

Giuseppe’s Ponza Island DXpedition with the Icom IC-705

Report from Ponza Island: May 6-9, 2022

by Giuseppe Morlè (IZ0GZW)

Ciao Thomas and Friends at the SWLing Post!

This is the summary of 3 days of testing of my Icom IC-705 just purchased and immediately taken to Ponza Island, my hometown, for a full immersion DXpedition only listening to amateur radio bands especially on 20 m.

Day 1

I left Formia on the ship that went to Ponza and it was not a good start given the adverse sea weather conditions. After 3 hours of crossing in the rain and the strong sirocco wind, I arrived on the island at my father’s house.

In the early afternoon in the rain, I hoisted a 20 meter row on the “sloper” type roof not so high from the ground and connected directly to the Icom 705 without any counterweight given the place without electrical noise.

The position of my father’s house is open from West to North but totally covered to the South by a hill of 200 meters …

In this video you can see all of this:

During the first night, 20 meters was full of signals especially from the USA; it was, in fact, what I had hoped for given the position open to the West.

Really good overseas signals despite bad weather … below is a series of mixes of North American stations: Continue reading →

Giuseppe’s Crossed Loop and the “VariabilOne”

3 Replies

Many thanks to SWLing Post contributor, Giuseppe Morlè (IZ0GZW), who shares the following:

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.

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!
