This is a review based on real-life operation of the TS-590S from Kenwood. If you are looking for dynamic range measurements, please have a look at Rob Sherwood’s receiver test data. Note that the dynamic range at 2 kHz spacing is irrelevant for SSB since the transmitter IM is always stronger than that; it is primarily relevant for CW and some digital modes. And unfortunately his table lacks one column – the price: While all the “upper class” radios have very similar properties within just a few dB, their prices differ significantly.
