Why can't Icom do this?


I've been critical of my IC-7610 and the lack of audio spectrum display centred around the CW pitch frequency - the Kenwood 890 has it.

I recently came accross a design in Practical Electronics for a simple audio spectrum analyser and decided to build one as an experiment. The DSP chip cost less than 3 GBP.

I wonder why Icom can't do this?
