I got mine yesterday ..... without question, it's the best portable I've ever used. It's also capable of holding its own with a lot of the desktops I've used. Yes, there's the issue of it needing to be adjacent some metal (or body) to supply a ground plane, but that's always going to be an issue with portables.
40Meter CW during a contest at night, is perhaps the best test of dynamic range handling that there is , and the Belka did fine there. I could EASILY operate this as a ham receiver during a contest, it's that good. Oh, and this with just about 16" of the telescoping antenna extended.
I'm still learning how to use it as there's no manual with it, but it's pretty intuitive so far.
No BCB reception if that's important, but perhaps that contributes to its overall performance.
This thing is one of the performance bargains that's currently on the marketplace, and is the ideal portable SW rx. It's chargeable via the USB port too, so that solar panel you have can top it off in the field.
