Thanks for your report, Martin. For the reasons you state, I guess you will already have an Airspy HF+ on order!
Ha maybe :-)

Although I'm quite happy with my KiWi SDR's, so perhaps not just yet, I like to let designs settle down a bit first and the early adopters to be the Beta testers for me....

The particular application I had in mind for the cheap dongles requires something to be as low cost as possible, almost a throw away item. It only needs to be good enough for the purpose.

Judging from the woeful performance of many existing WEB SDR's etc. I suspect that only a few folks will have a good enough antenna system and low enough noise floor to be able to take full advantage of the sensitivity and dynamic range of the HF+. 

In many cases these days an 'average' performance receiver is probably good enough. Although that still shouldn't stop us striving for the best performance possible to deal with 'edge cases'
