1. You're getting quite some QRM from whatever surrounds you at your location, limiting sensitivity/reception. If there's a radio you can bring on outdoor activities away from civilization, it's the Belka and out there you might be getting even more (MW) stations! :) 2. Particularly on LW/MW, the Belka is much depending on a counterpoise. The speaker version even more, because it doesn't have the headphone lead attached to give it at least some of that. That's reducing sensitivity and causes the display noise to interfere when you don't touch the radio and it also shows that... 3. ...obviously, with some strong stations close to the radio you can get it to overload on MW if you touch it. This is probably due to the tuned input filter not being used below 1.5 MHz or so. Interesting, the closest MW stations to my place are weak and at least 200km away so I didn't know how much difference that filter makes, or had a chance to see how the dynamic range is a bit more limited down there.
This video was out in the country with only 1 house anywhere near. There are only 14 AM stations total near (within probably 500 km / 300 miles) where the video was done and I got all the ones I expected. Going out to some far away park is on the list of things to do.
