Is there an Alternate Reality Game hidden inside of Half-Life: Alyx?

I've now just finished Half-Life: Alyx and while I need it all to sink in before I write it over the next few days, an interesting development has happened in the form of an ARG.

What is an ARG you ask? An ARG is an Alternate Reality Game, where some gamers have begun to pick up clues of an ARG hidden within Half-Life: Alyx. The ARG itself begins at the start of Half-Life: Alyx where you will be faced with a radio, if you tune the dial clockwise you will access a radio station playing fuzzy music.

But, if you pull the antenna out and slowly turn the dial with your other hand, you will access a "numbers station". Over on the /r/GameDetectives subreddit, gaming sleuths have begun digging through Half-Life: Alyx and seeing what the hell this ARG is all about -- which is something I want to see completely ripped apart and detailed now.

Valve isn't a stranger to ARGs hidden in their games, where the original Portal having radios that led right into the announcement of Portal 2, and seeing ARG players rebooting GlADoS. It's an interesting game-within-a-game trick by Valve, and considering it's within the Half-Life universe it makes it all the more interesting.

Does this mean Half-Life 3 confirmed? Not just yet, but with over 500,000 copies of Half-Life: Alyx sold, and reviews of the game absolutely beaming (I'm personally calling it a masterpiece), it would come as no surprise to see Half-Life 3 in the near future.
