SAQ Christmas Transmission with RSP1

I recorded the SAQ Christmas transmission on 17.2 kHz with my RSP 1. Antenna was a home made PA0RDT mini whip active antenna.

Re: High noise floor on RSP2??

Did you try to reduce the gain on the RSP? The RSP has a limited dynamic range and can be easily overdriven with a good broadband antenna if gain is set too high. In this case the noise floor increases dramatically. How to reduce the gain depends on the SDR software you are using. I am running gqrx ...

Re: Why so much delay?

Half a second is quite a lot of delay. I am using the SDRPlay on Linux, mostly with gqrx but I also tested CubicSDR. I also see quite a lot of delay and did some measurements (triggering a dual channel digital oscilloscope with the RF pulse at the SDRplay antenna input and looking at the demodulated...

Re: The new SDRPlay: RSP2

This is exciting news indeed. My concerns regarding the 1.5 MHz limitation on the coax ports have been discussed. My other concern is that there is no API support yet for the RSP2. This would be a show stopper for me since I am not running Windows. I hope the RSP2 will be supported in future API ver...

Re: Proposed upgrades to RSP1 no cancelled ??

Hm, I would say most of the wishes for the RSP 1 have been recognized and the result is the RSP2.

Only thing I don't like with the RSP2 is the high impedance antenna input for VLF and LF. I am using an active antenna there which has a 50 Ohms output.

Re: API Drivers

FYI: API 1.97 works on Kubuntu 16.04 (soapysdr + gqrx)

Are there release notes anywhere?

Re: New API, new SoapySDRPlay and Ubuntu

Thanks Franco, that's the version I am running too.

I added support for the ppm correction so I can now match gqrx frequency with my TS590SG.

Re: New API, new SoapySDRPlay and Ubuntu

Franco,

where did you find the new soapysdrplay? Is it the one with the transfer mode patch or is it already ported to the new API?
