This project uses a PICAXE-18X to interface my Icom IC-910 to PowerSDR, the FlexRadio SDR PC control software, so when selecting a signal on the waterfall in PowerSDR it tunes the IC-910 to the correct frequency. This translates the IF offset from the centre frequency in both PowerSDR and the IC-910 and commands the IC-910 to the new frequency. This interface is used to control the frequency on my Icom IC-910H using the PowerSDR software. PowerSDR uses Kenwood CAT commands which is the first thing, [...]
