Thank you for the answer, I did not check QST Product Reviews earlier. So, there is another source with bad numbers while the clock seemed to be fine.
It is now 2:1 (albeit from different years...), plus a lot of statisfied people on the positive side even if it means what it means. This is because the radio has a "normal", very high, top-of-the-list DR (at 2 kHz) according to DC4KU as I mentioned.
I really hope that it turns out sooner or later who made mistakes, otherwise my hardly achieved knowledge and the connection with the pure RF reality will directly convert themselves to a common black hole...
And yes, I've read about that 80 dB from Rob Sherwood earlier. :-)
