The SDRplay API find the RSP1, but not the SoapySDRPlay obviously. Check you've got the udev permission rules installed; $ more /etc/udev/rules.d/66-mirics.rules SUBSYSTEM=="usb",ENV{DEVTYPE}=="usb_device",ATTRS{idVendor}=="1df7",ATTRS{idProduct}=="2500",MODE:="0666" SUBSYSTEM=="usb",ENV{DEVTYPE}=="...

SDRplay have released their API for Linux on x86 as well as Raspberry Pi. Third parties libraries are being upgraded to support this and the RSP-2 as we speak, but today you might not find your favorite library ready to use. The RSP-1 will work with most software today, though. Software explicit wri...

There's some confusion about selecting antennas in the new RSP2 API. mir_sdr_RSPII_AntennaControl() selects between SMA A and SMA B. mir_sdr_AmPortSelect() selects between the HI-Z antenna and ... ? How are the above support to work in conjunction? Need schematics! :-) The antennas must be multiplex...

I'm also wondering what's in store for the RSP2 when it has so many more components than the RSP1 as seen in this photo. Seems they had to add an extra micro controller, presumable due to the fact that the GPIO of the Mirics chipset wasn't enough for the additional preselector filters, new LNA etc....

Thank you SDRplay for the API release. I just compiled the old SoapySDRPlay driver against the new SDRplay API, and CubicSDR run as-is without any modifications. :D Of course, to get the new features of the RSP2 to work, they'll have to be added to the SoapySDRPlay code, but this is a promising start.

I'd say you need a scanner or radio spectrum monitoring software and not a general purpose receiver software such as SDRuno. Once the API for the RSP2 is released, you are not limited to SDRuno but can download, or ever write yourself, a program more suitable for your needs.

As long you only need to change the frequency within the capacity of the simultaneous bandwidth of the receiver (e.g. 8-10 MHz) you can do this in software without losing any samples at all. To change the center bandwidth of the receiver and sweep other chunk of 8-10 MHz, you will lose some samples,...

I am confused. The native API to RSP1 is supplied by MIRICS. This API no longer works for the RSP2 according to the SDRplay staff. Does this imply that the RSP1 follow the MIRICS SDR reference design by the letter, but the RSP2 not? Still, both are using the MSI-2500 USB interface, and this communic...
