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.
At the time while writing QSL.net is recovering, but I’ve not been able to find any public announce. Rumors, says a maintenance activity is ongoing, someone else reports a server outage.
This downtime should let us think about importance of QSL.net service. I would suggest all those who are using K3TKJ services to donate, or move their web sites somewhere else.
Our knowledge is too important to to be compromised by a single point of failure

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 will try to setup this inside my balcony.

According to his experience, using it form inside the apartament, european singals are all very readable, he has worked over 150 countries.

The antenna is made of 2mm wire.

The 2 coils are constituted by 18 turns of 2 mm wire, distance of tunrs is also 2 mm.

The diametre of the coils is of 7,8 centimeters.

The Feed of the dipole is done with a 75 ohms tv coaxial cable.

A 1/1 balun would be recommand for a correct feed of the coaxial cable to the dipole.

It is not necessary  to use a coupler, it is enough to set the length of both extremities of
the dipole in order to have at 7.050 mhz a low SWR, and especially to pay attention what the lenght of the 2 sides of the dipole to be identical.
