All of them make most of their money via commercial and gov sales, not HAM or swl. Icom even had a pc computer line at one time. HAM and swl production got them up and operating, commercial and gov sales keeps them alive.
With sdr chips becoming so cheap and prevalent, as well as higher bit depth adc chips, we might see some fairly spectacular swl rigs in the future. I consider the IC705 to be an example that just happens to transmit.
