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 →

The Icom IC-705: Giuseppe’s pairs his new radio with his homebrew crossloop antenna

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!

Giuseppe’s portable multi-loop homemade shoe rack antenna

Many thanks to SWLing Post contributor, Giuseppe Morlè, who writes:

Dear Thomas,

I’m Giuseppe Morlè iz0gzw from central Italy on the Tyrrhenian Sea, Formia.

I am sending you this umpteenth project of mine built with poor materials…it is a test bench, loops / capacitors to find the best tuning.

The frame is a shoe rack in beech wood, very light, to take anywhere or to try out at home.
On the frame, there are 4 different loops of different sizes and 3 variable capacitors with different capacities. Only one signal transfer link to the receiver for all loops.

With alligator plugs I can use the different combinations of loop / variable to find the best tune

This test rig can tune the whole HF frequency range and medium wave.

I’ve attached 3 videos where you can see from the beginning to the last test on the balcony of my house.

Note that the following videos are in Italian, but you can turn on closed captioning and in the settings of the video have it auto-translate into the language of choice:

All, as always, spending very little and employing used materials!

Thanks to you and a warm greeting to the whole SWLing Post community.

I remain available for any clarification.

Greetings to all and good experimentation!

Thank you for sharing this Giuseppe! I love your ingenuity and spirit of experimentation! What a fun project that obviously yields excellent results!

Giuseppe’s Homemade “Magic Tablet” Antenna System

Many thanks to SWLing Post contributor, Giuseppe Morlè, who writes:

Dear Thomas,

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

I built this “Magic Tablet. during a rainy afternoon to test various portables I have.

The tablet is composed of 2 separate circuits: one for the short waves, a single coil along the entire perimeter of the tablet, and another with 2 ferrites wrapped around 36 turns of telephone cable for the medium waves.

The heart of the system is a 1050 pf variable capacitor with its old wheel.

To listen to medium wave I have to exclude the short wave loop with a switch on the loop.

I also added another small switch to connect it to a capacitor for more or less capacity, but this I will do later.

I can test my portables like this because the tablet tunes very well from 500 kHz to 18 MHz. I spent very little to make all this as it is all recycled stuff.

You can see the first tests on the balcony of my house with a Tecsun H-501 via my YouTube channel:

Note: this video is in Italian, but you can turn on closed captions and have it translate into the language of your choice.

As I always say, I am not a technician and I have little manual skills in building things, not having a proper laboratory. When I get an idea, I put it on paper and I start to find all the materials and then see if they work. Not all of us are of the experts in electronics–what drives me is a passion for radio listening. Now being retired, I have more time to devote to it.

Thanks to you and hello to the whole SWLing Post community …

I love this, Giuseppe! What a clever all-in-one portable antenna system for your shortwave radios. I especially love the fact you were able to create all of this from parts you have at your home. You’ve got a winning attitude, too: build and experiment! Thank you for sharing.

Giuseppe’s Homebrew “TFerrite 2” Mediumwave & Shortwave Antenna

5 Replies

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

Dear Thomas my friend,

I built another Tferrite, (TFERRITE 2), for medium waves–this time also with the shortwave option.

A single variable capacitor, 800 pf, and a primary winding on the 2 ferrites of about 46 turns, a secondary winding of 3 turns to pick up the signal and send it to the receiver.

On the PVC tube I wound 4 more coils, for the shortwaves, connecting the ends to the same variable together with the other ends.

I interposed a switch on one end to eliminate or insert shortwaves.

I am sending you these 3 links from my YT channel where you can see the tests I have done in these days with no propagation.

The yield in mediumwave is excellent, like the other one, yet also good for the shortwaves–to be so small it compares very well.

Let me know what you and the whole SWLing community think!

Thanks to you and a greeting from Italy, Formia on the Tyrrhenian Sea.
73. Giuseppe.
