One point to remember is if you bias the audio you should keep all the bias voltages the same or as close as possible. If not each time you switch between them you will be forcing the caps to either change or discharge to the new dc conditions. Causing switching pops etc.
You are right - I really should have run the output through a speaker to see if there were any audio artifacts there. Definitely going to do that when I have the switch hooked up to the ESP32-A1S. Thanks for the comment
Hi Paul. I use the "fab in a box" kit and etch the PCBs. I did a quick video on the process a little while back ruclips.net/video/X5O1au3FvRc/видео.html Thanks for the comment!
Video penjelasan paling baik yg pernah saya lihat mengenai SDR transceiver . Ditunggu video selanjutnya.
Terima kasih! (I hope I got that right ;) )
Great video as usual! I love what you did with the audio switch :)
Thanks Andre - we'll see if it works in the real circuit! ;)
Thnx, great content!
@@ploegmma Thank you Majodi
Great video, thanks! 👍
Thanks Alex

Great videos. I may have missed it in an earlier video but how do you make your PCB’s. Are you using a CNC machine?
