Welcome to EA3UU
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.
My high performance line 4 Drake
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.
Nothing as simple as installing the DDS VFO R-4C antenna on the glass of a window from which the sky can be seen. To see in more detail how this state-of-the-art equipment works, you can download the user manual.
Current line 4 + DDS VFO
- Frequency coverage: 1.5 to 30 Mhz in a running band.

- Frequency stability with the new DDS version 10.0 with built-in 10 Mhz GPS external reference: +/- 0.01 Hz , so you don't need any further calibration.
