The initial results on the SDR are good - I've used the setup on an internal antenna and it's received Band II FM stations, my own transmissions on 70, 144 and 432MHz as well as aircraft and various 'utility' transmissions around 433MHz.
I'm just awaiting some hardware to arrive so that I can connect the receiver up to the external antennas such as the triband vertical for 50/144/432MHz and see what I can hear.
You may have seen a post indicating that Dave, G4ASR had some problems with his dongle showing up as a different device. Happily that has been resolved - Dave took the IT professional's approach, deleted all the files, started again and it worked fine. And no, I'm not being sarcastic! Glad it worked - I was feeling guilty that it hadn't been straightforward.
