Receiver finalized.

Hi,

I finished my second semester exams and I was able to finish the receiver, thanks for your software, so that the rotary encoder works in a clockwise direction I have changed the wiring, CLK pin 5 and DT pin 4, I look forward to PBT L and PBT H be active. Now I have time to have fun with the receiver.

Regards.

That's good notice. To use the Low and High cut filtering, take the related func button pressed when rotate the tuning control. This Dynamic filter help you to change upper or lower side of filter. Have a nice listening and stay tuned for news. 73 de IK8YFW -- Inviato da Libero Mail per Android giovedì, 25 marzo 2021, 10:50PM +01:00 da Haranochi ***@***.*** :

I have a notice that the audiosdr library ( the engine on my project ) have a new release that solve the distorsions problem on AM demodulation. I cannot test It at the moment because I'm working in other sdr chain. If you dewnload It and recompile the project please send me the results of tests if possible.

Hi Guiseppe,

Thanks for your notice, happy to be able to test your new modifications, a question, the files downloaded from your github page once unzipped are dated February 21, these are the ones that contain your latest sdr library. And thanks for showing me how the high and low cut filters work. I send you my comments.

No, the news are in the external library audiosdr that I used in compile, you must download latest audiosdr and recompile my project. You can find the library here: https://github.com/DerekRowell/AudioSDR -- Inviato da Libero Mail per Android domenica, 28 marzo 2021, 01:35PM +02:00 da Haranochi ***@***.*** :

Hi Giuseppe,

After adding the file "core_cm4_simd.h" to / Arduino / teensy / avr / cores / teensy4, it compiled without problems, only three warnings:

RDSP_convolutional.h: In function 'void doConvolutionalProcessing (float, boolean, double, double)':
RDSP_convolutional.h: 231: warning: comparison between signed and unsigned integer expressions
if (Q_in_L.available ()> N_BLOCKS + 0 && Q_in_R.available ()> N_BLOCKS + 0)

RDSP_convolutional.h: 231: warning: comparison between signed and unsigned integer expressions
if (Q_in_L.available ()> N_BLOCKS + 0 && Q_in_R.available ()> N_BLOCKS + 0)

RDSP_convolutional.h: 342: warning: comparison between signed and unsigned integer expressions
for (int i = 0; i <N_BLOCKS; i ++)

RDSP_display.h: In function 'void Update_AudioSpectrum ()':
RDSP_display.h: 214: warning: unused variable 'low'
int low = 5;

I have downloaded it to the Teensy and begin testing this afternoon / evening. When I make the comparisons I will tell you, if you think it is convenient I can send you a file with the audios.

Great! I upload the binary, now the AM mode works really well, you can tune it better without distorsion or tone. G.
