Glad you finally got yours too! Yes indeed, what strikes me most is that it never makes me think "aw, if I had a big antenna connected now, I could hear this" when I'm DXing on walks. Re MW DXing, I'm incredibly curious if "transatlantic DX on walks" could be a thing, for that I bought a little (well, still big in relation to the Belka) amplified and tuned MW ferrite antenna that can be attached directly to the radio.
I'm pretty sure that should work at least for the blowtorches (well, 50kW lol) WBBR, WINS, WBZ, VOCM.... and I tend to think this should be even easier in the opposite direction, trying to get Absolute Radio 1215 or one of the "split-frequency" real (400-600kW) blowtorches in northern Africa and the middle east. The best time to try this would be much more biorhythm-friendly on your side too, starting probably an hour before sunset. Unfortunately my new Belka got a bit sick and is on its way back to Alex, at the same time I ordered another one and it seems both parcels are stuck at their respective airports waiting for a freight plane to their destination countries, so I can't really test how it goes. On top of that we seem to be in the "mid-winter D-layer anomaly" at my northern latitude now, so there are currently no TA signals, at least not from North America so I guess I'll find out in 8-12 weeks only. But before that happened I compared the Belka with my IC-705 on the YouLoop indoors with WBBR 1130 and the AM2 sync detector made the Belka present that station even a tad better than the Icom! The other station I tried that night was WINS 1010 and that worked as expected on USB (to get rid of the signals on 1008 kHz), of course without any fine tuning needed.
I hope you soon get around fully testing and enjoying yours!
