The previous section on the IC-9100 on the website loosely describes the integration, but what I have found is that it has opened up many possibilities by not updating to a new radio at extra cost, and i guess, loosing money selling my old radio to boot. Not many good analog radios around.
I have also integrated 'HDSDR' software to work with the radio too! The radio, HRD and HDSDR all talk and work together.
So what are the advantages I see?
One of the packages I run is SDRuno by SDR-Play. I've got to say, it was a bit of a handful to learn in a short period of time. I had 1 week off work to learn and integrate everything to work together. For me, the guys at SDR-Play have done a really fine job on this software and although integration between all 3 units could be better, by using DDE to communicate with HRD for example, it has many added functions to enhance and expand your experience. What I am describing here is the 3rd party plugins (community based) they have incorporated into the SDRuno software, and most are all FREE! Including the SDRuno itself.
SDR in a main stream radio is good, but I have thought about it like any totally software run device, it limits what you can do from the manufacturer for example and in a self repair situation.
In any case, as i have discovered, this way of update has opened many other possibilities you can do in radio, by such a relatively cheap upgrade.
