Tayloe Mixer with Amplifier
This is just a quick video hooking up the Tayloe Modulator/Mixer
https://www.youtube.com/watch?v=zRPuAX_Dfn4&t=778s
To the IRF510 based amplifier
https://www.youtube.com/watch?v=D4UhOmum_oU&t=1s
and taking a look at the results
I was planning on comparing the results above with a commercial radio (a KX3 in this case) but I never got around to it. If there's anyone interested let me know in the comments.
0:00 Intro and setup
1:08 Simple two tone test setup
1:53 Two tone on oscilloscope
2:33 Two tone on spectrum analyzer
3:28 Harmonic calculations
4:06 Effect of I/Q balance on a single tone signal
4:43 Effect of adjusting IRF510 gate bias
5:03 Bias adjust on the oscilloscope
6:34 Bias adjust on the spectrum analyzer
7:28 Mixer output drive adjustment
8:25 Wrapup

PYBOA
pyboard-stm32f4-radio
In this video I use the digital signal processing from the earlier video:
https://www.youtube.com/playlist?list=PLsMaN1bGWynysVNJgQ9jhQnYDfqz3-Cd8
and build a radio replacing opamps for phase shifting with DSP on the F4. The tayloe detector used is described here:
https://www.youtube.com/watch?v=iwBk3jIxszI
The code is up on github here:
https://github.com/thaaraak/PyboardRadio
The pyboard is available here
https://pyboard.org/
Note I am not using micropython but rather just flashing from STMCube with
https://www.amazon.com/gp/product/B01J7N3RE6/ref=ppx_yo_dt_b_asin_title_o01_s01?ie=UTF8&psc=1
The results were not as good as I had hoped. It looks like I damaged the Tayloe detector board and I wasn't getting the upper sideband suppression I had hoped. I will spin another board and post results

PLAYI
playing-around-with-the-esp32-a1s-module
In this video I do some playing around with the ESP32-A1S module which has an ESP32 uController and an ES8388 audio codec on board.
I bought mine from Aliexpress for about $4 each (no affiliation)
https://www.aliexpress.com/item/2251832759134684.html?spm=a2g0o.order_list.0.0.1b631802RoYkxH&gatewayAdapt=4itemAdapt
Heres some links to the documentation available from the manufacturer
https://docs.ai-thinker.com/_media/esp32-a1s_v2.3_specification.pdf
https://docs.ai-thinker.com/en/esp32-a1s
Heres that site that allows you to determine whether you have the ES8388 or AC101 version
https://www.deeptronic.com/store/blackstomp-core/esp32-a1s-ai-thinker-audio-module/
Here's that USB to Serial board
