Kenwood and Yaesu, where are you?

ICOM’s IC-7300, r8500, IC-7610 and the currently upcoming IC-9700 are making huge impacts on AROs everywhere. This is no surprise to those of us familiar with SDR technology; older analog methods simply cannot offer the kinds of performance advantages a good SDR design can.

However, one thing these radios from ICOM have in common are some poor design choices; spectrum span choices are crippled compared to a center/demodulator tuning scheme; spectrums and waterfall displays that are insufficiently adjustable; noise blankers in the least useful portion of the signal path; insufficient “knobbiness”, so that the user interface of the radio is a great deal more clumsy than it actually needs to be.

The opportunity for Kenwood and Yaesu is clear: there’s an opening here to step in and knock ICOM off the hill they climbed up on.

Imagine a stand-alone SDR transceiver where:

  • You could conveniently place the spectrum/waterfall anywhere
  • You could adjust the amplitude/level of the waterfall and spectrum separately
  • Where the noise blanker reduced the noise on the display as well as in the audio
  • Where the display was capable of high resolution output to a monitor
  • Where transmit pre-distortion provided very high quality TX
  • Important controls were given their own front panel placement
  • Full mouse/trackball integration was standard
  • Broadband IQ output was available for external use
  • Multiband EQ and compression / limiting for TX audio are provided

These are just some of the obvious places where ICOM’s radios, thus far, have fallen woefully short.

Yaesu? Kenwood? Where art thou?

Kenwood TS-990S Review

ts990sI’ve been operating the Kenwood TS-990S for some months now, so it’s about time I actually review it. This review reflects operation under firmware 1.05 as downloaded from the Kenwood website.

Because there have been a number of reviews that have done an excellent job of enumerating the radio’s features, I’m going to come at this differently. I’m going to first give you an overview of how well I think it operates and how comfortable I’ve become (or not) with its features, along with an assessment of its value with regard to its capabilities. I’ll note a few things that seem unique to me, standout features that are really special from the operations standpoint.

Then I’m going to lay out, in detail, the critiques I have of the radio from an operating point of view — that’s something no one has really gone into as far as I know, and I hope you’ll find it useful. I even nurse a vague hope that Kenwood will, via Google-fu or some kind soul, find this and take some of my ideas to heart, because I really do think the radio could be significantly improved with just a firmware upgrade (or several.)
