Welcome to EA3UU
Stations, antennas, and much more!
On this page you can see how I built my loop magnetic antenna and the process of restoring and repairing my stations. I also dedicate a section to my lab and my fellow radio amateurs.
For those who still want more after having consulted this page, you can visit my Youtube channel, where will you see in more detail the assembly of my loop antenna and the repairs of my Drake, Icom and Kenwood equipment.
In addition to EA3UU, the world of amateur radio would not be complete without including such notable pages as URE, ARRL, QRZ or eQSL. At the bottom of the page you will find the corresponding links.

It has a built-in 10 MHz GPS outdoor reference, 1 Hz resolution, and requires no calibration. It can be used from the Ham Radio Deluxe and the DDS is also capable of directly controlling Icom equipment via the remote connector.
