[K3] QST Labs review? -- Pool?

[mvolstad]

Has Rob actually commited to publishing a detailed technical evaluation of the K3? If so, I believe that will be a first. I have searched his web site and cannot find detailed evaluations of *any* current HF rigs. His tables of receiver performance numbers are very convenient, but the numbers themselves do not seem to differ greatly from those found in the QST reviews. He also has a number of very interesting and illuminating white papers, but these are general technical discussions rather than detailed evaluations of specific radios.

Perhaps I'm wrong, but I thought there was also a good bit of controversy
some time back as to whether or not Sherwood's measurements were correct.
It might have been via the Orion reflector or the IC7800 reflector, but not
sure.  Anyway, as I understand it, Sherwood had to go back and do a
re-analysis on several radios.  Also, I seem to recall he had not really
correctly evaluated the K2 when it first came out.  But maybe I dreamed all
of this.

Rob will be testing a K3 on loan from one of the Colorado locals.  He does not publish full test reports on his website but they often show up on specific rig forums.  I believe his latest on the SDR-5000 was published by an SWL publication (Passport Radio?) but available to subscribers only.  Rob was on the IC-7800 list since he bought a unit (subsequently sold) and I would not be surprised to see him show up here.  In these forums he often shares qualitative observations that are not in his published data (e.g. the RX AGC impulse noise problems the IC-7800 and 7000 have).

So to answer your question, he does publish info but you have to look for it.  I suspect you may see something published here eventually.
