My youtube video in the link below shows a summary of how i got rid of the Atari 5200 switchbox that is bulky, inconvenient, prone to failures, and is expensive to replace. Even when it works, it usually does not give a clean signal.
I ditched the switchbox and RF altogether by applying two mods: 1) the switchbox bypass power mod from console5.com and 2) the UAV board from thebrewingacademy.com.
PLEASE READ THE NOTES SECTION OF THE VIDEO FOR MORE DETAILS NOT MENTIONED IN THE VIDEO.
I am not an experienced modder, and do not post a lot of videos, so i would really appreciate your positive comments and likes.
