Need a general purpose antenna on “6 – the magic band” ? The J-Pole is an easy-to-build and inexpensive device that provides an omni-directional vertically polarised antenna without the need for a ground plane. In technical terms, it is an end fed vertical 1/2 wave which is fed via a 1/4 wave matching stub. If…

Sun’s next phase of activity will be mild
According to the Indian Institute of Science, and in particular to Prof. Choudhuri, the next active phase of our sun will be rather mild. They have based the forecast using a new theoretical calculation, pointing out that some assumptions in the previous forecast model are unjustified. Their final forecast, is that upcoming solar cycle will…
Upcoming solar cycle will be a big one
Solar cycle 24, due to peak in 2010 or 2011 “looks like its going to be one of the most intense cycles since record-keeping began almost 400 years ago,” says solar physicist David Hathaway of the Marshall Space Flight Center. He and colleague Robert Wilson presented this conclusion last week at the American Geophysical Union…
QSL.Net is up again ?
During the last days QSL.net domain has been down. Ham radio community have been missing a large part of it’s web presence, and a valuable part of knowledge. QSL.NET was started in the winter of 1996 by K3TKJ, and host thousands of ham radio related web sites, email redirection services and mailing lists, for free….
Indoor antenna for 7 Mhz
I’m looking to setup a hidden / indoor antenna, and i’ve found a couple of interesting articles on hidden / stealth antennas This small antenna can allow hams which lack space to install an antenna for 40 meters. This project has been originally produced by F6CYV. I’m going to test this antenna in the coming weeks. I…
Italian ARI Contest in 40/80 Meters
Last weeked we joined the ARI italian contest 40 & 80 meters. Even if I’ve never enjoyed so much the italian only competitions, I must admit that I’ve been enthusiast.I operated the IQ5FI, club station, during the day-light hours, so, mostly on fourty meters, and has been a surprise for me, since the frequency was…
New QSL cards on the way
Finally new QSL cards has arrived. Myself and other local hams have been very impressed with the high quality of these cards. I promised in a previous post to give a final opinion on IT9EJW products quality. It’s a 5/5 stars. List of world wide QSL Printers Price for 1500 QSL cards has been 100…
My CQWW SSB
Yet another fun experience in contesting. I’ve taken part to the multi operator station IQ5FI last weekend for the CQ WW SSB international contest. I’ve been active since 00:00 till 03.30 Gmt of Saturday 28th along to I5UKS Paolo, and then again another night spent with IZ5GUL from 20.00 to 04.00 GMT of Sunday 29th….
Super Loop Antenna
G5RV verses Superloop 80 Many operators with small lots, a G5RV is what can fit for the 80 and 40 meter bands. The G5RV is 102 feet long and has a 34 foot section of twinlead followed by coax into the shack, possibly with some sort of RF choke on the coax. The ends are…
A Small wire loop antenna for 160 to 10 meters
An easy-to-build general purpose receive only small wire loop antenna As much as I like my coax loops, I am also quite satisfied with small loops made with wire or tubing. They have the same or better performance as the coax loops, but might require that you invest in a balun to help maintain directivity…
