This can happen if any other sdr software is running (such as SDRUno) when you attempt to run Dump1090.

The 'Loss of Cal Bug' also takes place when switching IF modes (Low-IF/Zero-IF).

CW AFC does not work either. Tune to a carrier and center it in the passband in CW mode, Enable CW AFC and listen as the AFC begins driving the tuned freq. lower and lower.

It also appears that the CW mode ZAP feature is broken. It was a very useful tool in SDRUno

You might also try this: Right click on the speaker icon (lower right side of task bar). Select 'Open Volume Mixer' - A window similar to this should open: Volume Mixer.JPG Rx Ctrl 0-0 is the level adjustment for SDRUno. It won't appear if SDRUno is not running. Also SDRUno has it's own level contro...

I have the same problem on my Asus M5A99 motherboard computer with an AMD FX-8320E Eight-core processor @3.5 Ghz Windows 10 X64 and Windows 7 X64 (dual boot)). I disabled several of the USB ports in the BIOS it helped somewhat. (It now begins to stutter at 4MHZ Decimation 1.) I tried my SDRPlay RSP2...

The RSP2 does not have independent antenna gain reduction settings. If one Antenna's gain is changed, the setting is transferred to the other two antenna choices. A real and unnecessary nuisance.

g1hbe: I have been able to reproduce this nasty issue in SDR# (where it is particularly bad) with all antennas disconnected from the RSP2. IMO, this is a serious compatibility issue that needs to be addressed ASAP.

Low/No cost lightning/surge protection: Physically disconnect antennas from the electronics when not in use

I use SDR# withe the RSP2. SDR# will frequently hang when selecting the HI-Z antenna port. Once a successful selection to the HI-Z port is made (which is rare) it works fine.
