Hello to everybody visiting this page. I have been a licensed Amateur Radio Operator since 1985 although the first ever crystal radio goes back to 1958, at the age of 8 years. I am not a member of the SV QSL Bureau, but if anybody needs a card sent an empty envelope with your address only, with NO IRC and NO GREEN STAMP. Just put as many stamps as you can on your envelope for my collection. I will be very happy to reply. All QSO's are uploaded every last day of the month in LoTW. Note. If any ham connected with the EuroBureauQSL (www.eurobureauqsl.org) sends me a QSL card, i will responde the same way asap. .
UPDATE: March 1, 2012 This is the vertical aerial end fed antenna with a more heavy construction. On top section now i have a 7m fishing pole, at the base a 4cm diameter baboo and heavy duty 16 atmosphere plastic pipes at the connection segments. Among the first QSO's was a station from GUAM in 40m and a 55 report for 100w input. More info in my blog http://sv2yc.blogspot.com/2012/02/vertical-end-fed-1175-m.html
I install a new antenna for 10m band to work the great openings that are comming in the new solar cycle. The antenna is a rectangular shape loop and is constructed with very simple materials as usually. Is tuned for 1:1 SWR on 28.300 and gives me 1.5 : 1 up to 28.500, so i need the tuner above this segment of the band. All the reports in the first couple of days are 58 to 59+15 Europe, North America and Japan. Among them Noth Dakota (new one) with 100W gives me 58 on the first try. Update. The antenna was an excellent receiving antenna in the second receiver of the FT1000D in the CQ160m 2012 Contest. More details in my blog http://sv2yc.blogspot.com/2011/11/rectangular-loop-antenna-for-10m-band.html.
You can see some Photos of my shack, my lab bench and the antenna farm on the rooftop.
My shack with the FT-1000D, FT-102 and FT-901. At the upper right a combo with the GRC-109 Surplus Set. Some in house loops for receiving low bands and upper left a coplanar loop for 20 m band with excellent reports.
The roof of the house with the 0-cost rotary dipole about 25m above ground. The antenna was made with two natural poles from a nearby plantation, three surplus aluminum tubes for mast and piece of wood as center support. The antenna is a full size dipole with a 6wire nylon enameled conductor fixed on the poles with tireups and a Fritzel 1:1 balun at the center.The antenna stays as it is for 3 years, and i rotate it with my hands according to the position of dx stations (not very often). Usually the dipole points to 320 degrees covering NA and VK. I didn't miss any QSO even with Hawai or New Zeland. I usually operate the FT-1000D with 100W only, and sometimes the FT-102 with 150W. A new 10m dipole with the same tecnology was made for the 10m ARRL DX Contest. I hear a few stations, i made all the QSO's but propagation was a beautiful zero.
The new 10m antenna. In the foreground lay down the new poles for the 20m dipole. A closer look with the new improved wood base and new baboo poles. A new antenna is now operational as you can see in the following photos. It is an end fed wire with a homemade 9:1 UnUn at the end, connected to the radio via a T-tuner. The lenght of the wire is 20,50 m and the coaxial cable is 40m of RG213. No counterpose is used due to large lenght of the coaxial which acts as a virtual ground.
More constuctional details are in my blogs, sv2yc.wordpress.com and sv2yc.blogspot.com.
In the above photos you can see the antenna in the slopper configuration ending in the pole plantation, and the matching point with the 9:1 UnUn. Last modified: 2012-03-01 21:17:22, 6229 bytes cached
