Re: RSP1 & RSP2 under GNURadio

So the SoapySDRPlay driver returns RFGAIN and IFGAIN. I am running gqrx, and it is showing the gain settings the driver offers. The gnuradio block always seems to offer RF/IF/BB gain stages which needs to be mapped to the native gain stages of the hardware. Regarding RFGR in the RSP1A, I am missing ...

Re: RSP1 & RSP2 under GNURadio

Hm , I think I am running the same setup here but I get IFGR and RFGR with my RSP1A.

Some time ago I did some tests with the non-free sdrplay driver (not the soapy driver) and IIRC I got different gain settings.

What device string are you using? I use "driver=sdrplay,soapy=0"

Re: gr-sdrplay for SDRplay API 3.01

Hi Franco, I am running gqrx with gr-osmosdr, but not with the SDRPlay module but with the standard "soapy" module, which then uses the soapysdrplay driver. This is because when I started with SDR, the existing gr-osmosdr module for SDRPlay was incomplete and seemed to be unmaintained. I also tested...

Re: gr-sdrplay for SDRplay API 3.01

Hi Franco, this is a bit off topic but I would like to know if the gr-sdrplay with the 2.x and/or the 3.x API brings latency improvements over the Soapy SDRPlay approach which is commonly used on Linux. For me, Soapy SDRplay is working fine with gqrx, only issue being the quite high latency. So I do...

Re: VFO knob for RaspberryPi

I am running an ELAD TM-2 controller with Linux using a home made driver programmed in Python that should work with a Raspberry Pi. This is not a VFO knob alone but a complete controller with display, see pictures. It controls my TS590SG and my RSP1A with gqrx. 2018-11-02_00-30-44_v1.jpg 2018-11-02_...

Re: GNU Radio support for educational use

That's great news!

I am running the RSP1A with gqrx using soapysdrplay with good success but it always seemed a bit clunky to me. I'm going to play with gr-sdrplay in grc and if that's working, I try it with gqrx.

Thanks a lot!

Re: gqrx Opinions ?

Hi Bob, I'm running gqrx with an RSP1A on Linux, so I can only comment on the program itself (features, GUI etc.), not the installation process, but it's basically the same situation on Linux as on MAC: You have only two choices, gqrx or cubicsdr. I also tried cubicsdr, it's nice but when I tried, i...

Re: FT 990 IF output

I you want to use the RX out, you need a splitter because the RX ANT button on the FT990 simply opens the connection from T/R relay RX side to receiver input and makes them available as RX out resp. RX in externally. I use a Micro Circuits PSC-2-1 for this. This gives a 3dB loss, but that does not m...

Re: Rig Control Delay - IC7300

Do you have bidirectional synchronization enabled (so if you change the frequency on the 7300, SDRUno would follow)? I see the same problem with an old FT990 at our club station but did not investigate it yet. If I configure the unidirectional synchronization SDRUno -> FT 990, the TRX follows SDRUno...
