Born on 1951 in Rome (Italy)
Graduated on 1972 in "Radio-Communication Technologies"
Got 1st Amateur Licence in 1973 as IW0AEV enabled for low-level Power on VHF and up only.
Achieved the definitive licence on 1978 as I0YLI (Max Power on HAM ALL BANDS).
Married since 1980 ; living in Rome near to the University "Tor Vergata".
My job consists in technical support on Medical Diagnostics.
My Ham-Radio activity has been, along the years , mainly on VHF and EHF (DX only);
although more than 200 countries have been worked on HF bands.
On VHF (144MHz SSB/CW) I performed several DX QSO's via TROPO, ES, FAI, MS, etc.
working all mediterraneus countries and more than 200 EU Squares.
I was the first one in the world (on 1982) to perform a QSO over 1.000Km on 10 GHz band.
On 1983 I reached the world record on 10GHz covering a path of 1.660 Km.
Starting from 1998 , still at present days, I am working mainly on VHF DX .
VHF I0YLI's STORIES
Since 1977 until Oct.1998 I was living on the North-West part of the city (Rome) lodging in a family house.. www Loc. was : JN61FV .
Beeing there, was possible to install, on the roof, a nice tower 12mtrs-high where took place a long-beam 20Elem. VHF Antenna, HF beam, Half-wave dipoles, MW dishes, and other stuffs (I was the roof owner !) .
Along 20 years many interesting Dx Qso's have been made on VHF and other bands. As portable station I performed "Long-Distance" QSO's on 10GHz band achieving world's records.
On 1998 I left that house (due to job and family reasons) moving to the opposite area of the town (South-East side) ; the new (and still today) house is located into a multi-flat 25mt-high building and I live at the top flat just under the roof (Loc. JN61HU)
Tower installation and big antennas were not permitted by the neighburg which were afraid of interferences (TVI);
A very poor VHF 6 elements on a short pole and Low-Power transmitter were the only chances ... so NO DX at all for several years.
On June 2009 (after 10 years) somenthing new happened :
- I received a gift from IW0AIJ (my brother-in-law): a new home-made DK7ZB 10Elem. 3WL VHF antenna !
- At same time in central Italy all TV broadcast stopped analogue transmission and digital-mode-TV started.
So I raised a square-shaped pole 10 mtr. high on the roof of the building ; I installed my CDE rotor and the new antenna on top of it.
I ensured all people around about TVI-less (I tested my system even using some hundreds watt out-put on 144MHz band).
Starting from that moment a new VHF DX season has opened to me ...
Since few years ago I was using my old rigs: FT225RD ( MuTek Front-End ) and more recently IC-7400 + 4CX250 home-made PA.
Most recently a new 12 Elem. - 4 WL has been manufactured again by IW0AIJ and now it is standing on my tower !
On last weeks I provided to replace the VHF P.A.: A VHF Amplifier, push-pull 4CX250 equipped, is in the shack now running about 800W p.e.p.
Along last few years I'm operating on the "magic band" (50 MHz) as well .. specially during ES/TEP openings ...
Also for this band a very simple antenna has been manufactured by IW0AIJ : the japanese project HENTENNA ...
This very simple "frame" allowed me to work more than 200 squares and very interesting countries..
like this one.
144MHz Band : TECH STORY
Since year 2010 till now, every year, along all seasons, even with a rainy (or snowy) wheather,
during almost all week-ends, a QSO, between me (I0YLI) and DK1FG, takes place: path = 870 Km.
It might look normal , but analyzing better my location and my rig conditions, it is not that real.
Looking at my QTH, using Google-Earth's maps (Sat-View), there is not a good take-off torward North from my location ...
In addition, the related path profile is plenty of terrain obstacles close to mine and german station related QTHs (see picture) ;
of course no meaning about the Alps mountains heights ... they are very far both sides !
Red Line = path profile.
Anyone can see along the path there is not a particular sea-duct nor any Natural Channel either
Let's go to my rig now: it is not a QRO PRO station ! But a simple old-fashion shack:
- RTX = Yaesu FT225RD with MuTek Front-End - (Today IC-7400)
- P.A. = Home Made 4CX250 running 300W p.e.p.
- Antenna : Long-Yagi 12 Elem. DK7ZB - 4 W.L.
It is really a standard one ! Although when Gerhard (DK1FG) starts to call beaming to Italy, quite often, myself ONLY (I0YLI) is able to get in contact with him and none else all around ... Except those which have a very Hi-Gain antenna system and/or Hi-Power rigs (>500W) .
Any explanation about this phenomena will be welcome.
My today's equipments are as follows:
VHF - 2mt.
- ICOM IC-7400 (all-mode 100W)
- Power AMPLIFIER: 800W p.e.p. Home-Made (2 x 4CX250)
- Antenna : 12 Elem. DK7ZB Long-Yagi (4WL) - 25mt. agl.
VHF - 6mt.
- ICOM IC-7400 (All-Mode 100W)
- Antenna: Home-Made HENTENNA Full-Size
- Baofeng UV-3R - 2W Dual Band FM Only
- Antenna: 10 Feet (3mt.) height Dual-Band Vertical Collinear - 20mt. agl
- ICOM IC-7400 (All-mode 100W pep) All HF Bands
- Dedicated Built-in Tuner
- Antenna : Multi-Band Home-Made Dipole
