These data comprise my FT8 receive only logs from about 2022 until now. These logs were collected using my local KiwiSDR and an LZ1AQ loop antenna.

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

Effort was put into sanitizing, de-duping, and ensuring that only one instance of a given station was counted per band.

I will continue to update this page as more logs are gathered. I have a much better directional antenna for 160m and 630m. I will also be investigating other modes.

I have also produced summary statistics for my NDB* and AM BCB Loggings.

* 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.
