Re: Request : Out of range warning

If you don't want to download the zip file, create a new text file and call it lower_freq.reg (make sure it doesn't have a hidden .txt file extension). Then copy/paste the contents from here: Windows Registry Editor Version 5.00 [HKEY_CURRENT_USER\SOFTWARE\SDRplay\Settings] "LowerFqLimit"=...

Re: Request : Out of range warning

To set a lower frequency limit... Make sure the SDR application isn't running. Extract the lower_freq.reg file from the lower_freq.zip file attached to this post. Edit the lower_freq.reg file in your favourite text editor and change the following line to your required value... (NOTE: The value is in...

Re: Request : Out of range warning

The upper 2GHz limit is the upper limit. The lower limit of 100kHz can be removed by adding a registry entry (make sure HDSDR isn't running)... \HKEY_CURRENT_USER\SOFTWARE\SDRplay\Settings Add a key called LowerFqLimit and set a value in kHz as your lower allowable limit. 0 should also work. Perform...

Re: SDRPLAY linux commandline tools?

For 16bit samples you will need to do 2 things... Firstly, the following lines will need to change from... for (i=0; i < samplesPerPacket; i++) { buffer[j++] = (unsigned char) (ibuf[i] >> 8); buffer[j++] = (unsigned char) (qbuf[i] >> 8); } to for (i=0; i < samplesPerPacket; i++) { buffer[j++] = ibuf...

Re: SDRPLAY linux commandline tools?

ok, I've modified rtl_sdr.c to work with the RSP. 16bits are right shifted to 8bits for compatibility. 16bit version is easy to do if needed. I don't have a way of validating the output so if it's wrong (may need +127 as well as right shifting for example), let me know how you are validating it and ...

Re: SDRPLAY linux commandline tools?

I thought you just wanted the IQ values. I'll take a look at rtl_sdr.c

Re: SDRPLAY linux commandline tools?

Please note the output is 16 bits, not 8 bits as per the RTL dongles.

You'll need to covert to 8 bits if you want a compatible format.

Re: SDRPLAY linux commandline tools?

Just a simple piece of code to take in frequency, sample rate, IF bandwidth and IF mode and then output raw IQ to stdout ./rawIQ > output_file use ./rawIQ -h to find out the input requirements. Run without any options the code has some built in defaults which you can change to suit if that's easier....

Re: rtl_tcp server

./sdrserver starts it in "daemon" mode, ./sdrserver -g will run it in the foreground. Someone asked for native gain support which I think means a gain lineup to be compatible with the RTL version. The RSP works with gain reduction (i.e. the amount of gain reduced from the maximum gain). It...
