Phaser Build Part 5 - Phase Shift and SSB Test
In this video I continue the Phaser build and pull together the phase shift network and RF combiner. I then test the lower sideband suppression on the spectrum analyzer.
I did check the manual and the lower sideband suppression should be -35dB down between 800-2800 Hz. I was only getting that between ~1200-1800Hz. That could certainly be related to the replacement FST3257 I put in. I will check again after the transmit stage is complete.

SIMPL
simple-electronic-game-with-black-pill
In this video I build up a simple electronic game based in part on the 1970s "Simon" game. I chose a Black Pill STM32F411CE based board but this could be equally done with the cheaper "Blue Pill"
I was inspired in this by Big Clives teardown
https://www.youtube.com/watch?v=3ss-1cu5gtA&t=733s
and there is a fantastic reverse engineering of the game here:

SSB A
ssb-amplifier-version-2
In this video I use the circuit developed in my earlier video
https://www.youtube.com/watch?v=efGYnsF4bDU
and create a PCB as well as some heat sinking for the BS170s
The LTSpice model is here:
https://github.com/thaaraak/ltspice
and the kicad schematic and PCB layout is here:
https://github.com/thaaraak/SSB-Amplifier-V2
Apologies for not being able to walk through the math on the second stage. Still looking for a good explanation for the collector feedback model. Also the result deviated significantly lower than the LTSpice model so I have some research to do!
Correction: Around 9:20 I say "22 ohm resistors" I meant to say 220 ohm

20M S
20m-ssb-amplifier
I thought I do a video showing show experiments I have been doing for a 5W push pull style amplifier at 14 Mhz.
Charlie Morris has a great video explaining the math here
https://www.youtube.com/watch?v=CtyabG69d4g&t=1503s
The push/pull style amplifier is based on the Ensemble RXTX power amplifier described here
http://www.wb5rvz.org/ensemble_rxtx/10_pa
The ltspice circuit is on my github repo
https://github.com/thaaraak/ltspice
Note that the original ensemble amplifier sets the bias of the mosfets using a reference circuit which I did include in the ltspice model - but I used a simple 5V regulator in mine.
Here's the site that I used for the lowpass filter
