+From nightly 23-08-19 onwards, we revised and  extended a good functionality of  all low bit rate bandwith REC options 
+If you adjust correctly the GAIN and LNA  and center freq. it is possible to capture good bit streams in C16 / C8 format , 
+Pls. find attached some examples , capturing the same tuned AM broadcasting , using MF upconverter ,

+Depending on the tuned frequency, (mainly most visible in  25khz, but also less visible in  others BW <100k )  we may got a random strange left picture effect -on the screen -   with “vertical stripes” , this can be easily corrected, just readjusting the center frequency  some Hz up or down ,  till trying to have full convergence of all red carriers to the central unique one , with +-10Hz steps. (It is pending to check and investigate different decimation filters or channel filters , to solve it and achieve a good performance as we have in the low bit rates 12k5 , 16k )
