Here is a screenshot from Google Earth of the NDBs I have logged so far. PIA (Piacenza) and LRD (Lerida) were logged during the dead of night using a recorder as I am not a late night listener now that I am a little older!

I have also redesigned the NDB loop using 90mm PVC trim. It is 60cm in diameter with 20 turns of bell-wired, tuned with a 1000pF variable capacitor. It is twice as large as my first prototype and SHM (Shoreham) comes in all day now, whereas previously I had yet to log it. I read there is 10% more efficiency when you use a pure loop over a square or diamond. I am certainly delighted with it. Here it is in the garden:
