Re: GQRX crash, OSX, RSP2 and SoapySDR

Yes it's a soapysdrplay or gr-osmosdr problem (Don't remember exactlly which one). It raises an exception if a function is not supported (instead of simply returning an error). I fixed it some time ago on my local build and thought it is now fixed upstream. Do you get this crash if you disable the i...

Re: SDRuno - Rig Syncronization

This is a problem I encountered in my home made synchronization solution under Linux too. If there are modes that exist only on one of the rigs, there is a mapping needed in both directions. Unfortunately this mapping is not always 1:1, but can be 1:N. In my implementation I have some "heuristi...

Re: Ubuntu 16.04 current soapysdr and built sdrplay module fail.

GQRX isn't working, but I think I just have to build gr-osmosdr with the non-free switch to get there. This is not required if you are using the soapysdr bacckend in gromosdr. But I think you need quite recent grosmosdr and soapysdrplay for working with API 2.x and RSP2. (I have an RSP1 so I can't ...

Re: MAC API Breaks GQRX

I am running Linux, but maybe its similar... grosmosdr by default has no support for the SDRPlay. You have 2 choices: 1. Build grosmosdr with non free drivers enabled 2. Install soapysdr/soapysdrplay (preferred method). I had to build it from source. You need quite recent versions of soapysdr and gr...

Re: RSP1 with Yaesu FT-1000MP Mk V

Maybe you have to configure your FT-1000 to actually use the RX IN input? On my TS590SG, I have to do this, otherwise the TRX antenna (SO239 socket) is used. What happens if you connect your antenna to the SO239 socket? On the TS590SG, I have to enable the RX out function too, because using the RX o...

Re: Audio latency and CW QSK

Unfortunately if have no suggestion, but I am suffering from the same problem. How long is your delay/latency? I measured about 130ms from antenna input to audio output on a good day (it depends a bit how the audio output buffer size is adjusted) and that pretty much destroys any QSK. I am running L...

Re: RSP2 and Linux

I just noticed in the document that for CubicSDR I have to build wxwidgets from source. On Ubuntu 16.04 I just installed wxwidgets and wxwidgets devel packages and could build CubicSDR just fine and it seems to work without problems. Is there a problem with the standard wxwidgets that I just didn't ...

Re: SDR play connected via IF out and transmit

I have my RSP1 connected to the RX antenna output of my TS590SG without any protection. No problems so far. I also tested with an active whip antenna connected directly to my RSP1. The whip delivers about 10 dBm when I transmit. This might be considered dangerous, but no problems so far. Transmit po...

Re: CubicSDR working fine, Gqrx not so good.

Got soapy working with gqrx needed to change the driver string to 'driver=sdrplay,soapy=0' now to work out how to change the antenna. Seems to be unsupported: /******************************************************************* * Antenna API *********************************************************...

Re: CubicSDR working fine, Gqrx not so good.

I am running gqrx with the soapysdr (not the gr.osmosdr non free) driver and have seen this same behavior. gqrx sets the default bandwidth to 0 and expects that in this case the driver calculates the optimum bandwidth for the configured sample rate (I think that's a gnu-radio convention). With soapy...
