Hi! Has anyone on here used an SDRPlay RSP as a downlink receiver when working amateur satellites? I ordered one last month, and it has worked fine with a laptop running Windows 7 Professional. At the time I received mine, I had Windows 8.1 on my 8- and 10-inch tablets. I could install the Windows API and the plugins for HDSDR and SDR Sharp, but the SDRplay wasn't recognized by those programs. When I upgraded my tablets to Windows 10, I tried reinstalling the API and plugins. Until today, it still would not work. An API update released earlier today (v1.5.0) has resolved the issues with the SDRplay and Windows tablets. I have not used my SDRplay when working satellites yet, waiting to get it working with my tablets. I think this should work like the FUNcube Dongle Pro+ I have been using as a downlink receiver for some time. The SDRplay has front-end filtering, and a much wider receive bandwidth, than the FUNcube Dongle Pro+. The SDRplay can work with an input bandwidth up to 8 MHz. On the tablets, the default 1.566 MHz input bandwidth seems to be the most I can use without overloading the tablets. This bandwidth is fine for the tablets, and I plan to reduce the bandwidth to 200 or 300 kHz when I use it to work our satellites. The SDRplay is retailing at US$ 149 from the SDRplay web site - about US$ 50 less than the FUNcube Dongle Pro+. The SDRplay is a small box, larger than the FUNcube Dongle Pro+. I want to run some tests to see which of these devices draws more power over the USB connection. This may not be an issue for some, but could be an issue when using a laptop or tablet in the field. Especially for some tablets with a single micro USB port, which can be used only for one purpose at a time - charging the internal battery, or (with a USB On-The-Go cable) using a USB device like these. 73!
