Well, I think the review was unbiased, but "unbiased" does not have to mean "unimpressed." When a radio of this price class has dynamic range that stacks up against the performance of what most hams see as the top-end radios, an unbiased review says so! I wanted to include a table comparing it with Model I, Model K, Model T and Model Y, but the editor shot it down. (A bit too "unbiased?" :-) ). Of course, the top-end radios do have a number of features that are found only in top-end radios, but if one wants basic top-end receiver performance, compare the number of the K2 against the numbers in the Reviews of the big-gun radios and decide for yourselves. > Having made a/b comparisons between my K2's and OMNI VI+ over many > months, the glowing independent assessment was no surprise.

So even though the OmniVI may have a bit better skirt selectivity, strong signals a couple of kHz away, even if they could be slightly audible in the passband, will not result in much, if any, blocking -- at least no more than strong signals 50 kHz away. The "Expanded Test Report" should be ready in a day or two, for those who want to see the numbers. 73, Ed Hare, W1RFI ARRL Lab
