I have been testing my Aziloop DF-72 loop antenna system since late June 2026.

The statistics were generated using Microsoft SSMS and SQL using my data extracted from SWLog. (Thanks Robert Sillett).

The idea for the summary statistics came from Loyd Van Horn at DXCentral (Thanks Loyd).

I have crafted summary statistics for both my FT8 (receive only) and NDB (Non-Directional Beacon)* logs.

* An aeronautical Non‑Directional Beacon (NDB) is a ground‑based radio transmitter that sends out a continuous signal in all directions, allowing aircraft equipped with Automatic Direction Finders (ADF) to determine their bearing relative to the station. It’s one of the oldest forms of radio navigation—simple, rugged, and still used worldwide despite the rise of GPS and more advanced systems. Now largely decommissioned in North America with only a small fraction of the historically many thousands of beacons remaining.
