Last weekend I participated in the “SQUEEZE 100” NDB event, organized by the NDBlist group. Aim was to log 100 NDBs (Non Directional Beacons) in an as small frequency range possible. Hence the name “SQUEEZE 100”.
I had participated in two earlier events this year in which I logged only 4 and 13 stations respectively. So I decided that I needed a bit of help and installed Pskov NDB software. The result was impressive. Not knowing what to expect I started monitoring between 300 and 500 kHz. After I had 100 NDBs logged I could start to zoom in a bit, trying to squeeze the frequency range.
In total I logged over 183 NDBs. Between 350 and 403 kHz I had exactly 100 NDBs, close to 2 per kHz! The picture above shows the most distant ones I heard. With 3033 km OZN from Prins Christian Sund in Greenland was on top of my list. I was also very happy to catch three beacons from Iceland (KF-392; VM-375 and HN-330) and two from Algeria (ON-415; BJA-423).
