I particularly wanted to try out Steve’s software. I would have bought a 1a to do that, but it didn’t have the option of the external reference input. When I spoke to SDRPlay at a rally they told me that the Dx version would be coming out soon, so I waited. Obviously, in retrospect, their datasheet for the Dx had some hangovers from earlier models, and as it said software was available I assumed it was Steve’s.
My bet is that Steve will be able to modify the software accordingly and all will be happy.
I emailed Martin Lynch to discuss that matter – but haven’t had a reply.
