Hi all I have just joined this email list as I became interested in incorporating WSPR code into a client I am developing for the ANAN-7kDLE Mk2 HPSDR Tcvr. This client app has support for the usual modes (SSB, CW, FM) and I would like to add WSPR mode too.
I used the rtlsdr-wsprd application as a starting point and have already incorporated most of the functions in it to my client. However, I am having difficulty understanding how to supply the decoder code with I/Q samples from my tcvr. As far as I can tell, rtlsdr-wsprd performs some type of mixing of the sample stream at 1/4 the sampling rate and then down-samples it to 375 S/s. In my client I have available the I/Q stream from the Rx at 192kS/ and also have a filtered and down-sampled stream at 48kS/s which is used by the demodulator functions. There is also the demodulated audio stream available at 48kS/s. I would like to know if it is possible to supply the decoder with the 48k audio stream, since this can be filtered to a narrow bandwidth to improve reception. I would also much appreciate any hints as to how I could use the un-demodulated IQ stream, if audio cannot be used. My Thanks in advance! -- Best Regards Neoklis - Ham Radio Call:5B4AZ http://www.5b4az.org/ https://www.qsl.net/5b4az/index.html _______________________________________________ wsjt-devel mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/wsjt-devel
