In this configuration, the system transmits the video output on channel 29. Devicemodder2 has also clarified that the transmitter used in this project is configured only for PAL audio but the signal passing through it is NTSC. As such, there is no audio output, just a video feed.
Devicemodder2 created this project in order to test old CRT TVs that could be sold to local thrift shops or flea markets. With a battery powered Power HAT UPS Lite V1.2 and transmitter both connected to the Pi Zero, you can make sure any TV is working without connecting the Pi to power or the TV itself.

In case you are interested, we recommend that you take a look at the original thread on Reddit for a more in-depth look at the project. Recall that, recently, we talked to you about how to install Windows 11 in an even easier way on Raspberry Pi. For more details, we advise you to read our previous dedicated article.
