Since there are no more analog TV stations on the air in this country, I have no way of testing sets I find it thrift stores anymore.
So, I finally decided to try the code that Charles Lohr developed for tricking an ESP8266 into transmitting analog TV signals over the air with its RX pin.
This is actually someone else's version of his code because he wrote his code to be compiled in the esp8266 SDK environment and I don't know how to use that. This code compiles in the Arduino IDE and it does work!
This is being transmitted over the air. This is not a composite video signal.
