I have both RSP 1 & RSP 1a. Since early February I have not been able to successfully record IQ files using SDR Uno. Only about 50% of the audio output is captured on the hard drive. When listening to the audio while recording, the audio drops out. This happens on both my PC and Laptop. Both are i7 machines with Windows 10, 64 bit. There is slightly less dropout when capturing to the SSD drive, but not much difference really. Similarly, if I set the bandwidth to 2MHz, there is less dropout, but it is still a significant amount. I have no recording problems when using SDR Console v3. I was using SDR Uno v1.3 when this problem began. I have now installed v1.4 on both machines. It has not made any difference. I assumed it was a Windows update which is causing the problem, but I have not read of anyone else having this issue. Any help would be appreciated.
