Ken, Check out a similar chart on the Elecraft website (Rig Comparisons) that uses data from the ARRL Product test data. The test setup for the ARRL tests is well documented. I did not see an indication of the setup used for the particular tests that produced the chart you referred to.
Without getting too technical (but hopefully not incorrect through simplification either), The noise floor is an indication of the strength needed for a signal to be heard above the receiver noise - the K2 is right on top of that list with the Orion. The narrow spaced dynamic range measured at a 2kHz spacing indicates how well the receiver will tolerate a signal that is 2 kHz away. Checking the notes on the recorded value indicates that that test measurement was limited by phase noise, so the real number may be higher (better) than indicated. The bottom line is that the K2 will hear weak signals on a crowded 40 meter band as well as the competitive best receivers and will allow you to read the desired signal in the presence of other signals nearby - and will do it as well as other transceivers priced in the $3K category. 73, Don W3FPR > -----Original Message----- > > > http://www.sherweng.com/table.html > > That's a link to a test page rating several HF rigs. > > It's organised by dynamic range "narrow spaced" > and the K2 does very well. > > Can someone translate this page into an overall > rating on the K2's performance in the real world? > > My target is 40m nighttime SSB use. > > -- No virus found in this outgoing message.
