If I wanted to emulate the FM radio signals that a FM antenna picks up, how would I do that?
I want to build a media server that plays to a FM radio in a giant retro cabinet that I picked up. I want to be able to turn the dial to various frequencies and pick up the media stream that I am emulating on that frequency.
It's just a signal coming down the FM antenna, right? So why couldn't I emulate them?
(don't be a retard and suggest other options like rebuilding the FM tuner with an arduino so I'm sensing the position of the tuner, or using a dozen mini car radio FM transmitter adapters)
I want to be able to take an existing FM radio, connect into the antenna, and broadcast to it directly.
How should I do this?

>Second: FM radio signals travel much better through wire than they do through the air. Connecting the transmitter built inside your Sirius unit directly to your FM radio antenna plug by wire will deliver a far more powerful signal to your FM radio. This will make sure the signal is loud and free from hiss.
So I guess the question is, how many FM signals could I stuff down one wire? Just one? Two? More?

You don't 'emulate' FM, you have to actually emit the FM signal. It doesn't really matter whether or not you connect the wire, as long as the transmitter is in the same room (at legal transmit levels, anyway). The issue you will find is that no one makes an FM transmitter that broadcasts on more than one frequency band, and most of them have an extremely limited range of bands. You'd find it much easier to generate one FM signal and change what is emitted from it than trying to hook up and configure a bunch of shitty china FM transmitters.

Thanks for commenting!
But what about this?

Does your giant retro cabinet have an AM band ?
I'm asking because amplitude modulation is WAY easier/poorfag to achieve than frequency modulation.
Bonus point is AM may give retro/shit quality that will fits well in you retro cabinet
(also MODS consider moving this thread to /diy : it's definitely not /vg related)

it's technology related
i'd be okay with AM or FM for this, but FM is better because stereo

How many channels do you want to receive in your cabinet ?
Also what's your budget ?

>I'm afraid you're fishing in a empty pond
yeah i guess i subconsciously knew that, i'd have had luck if i was asking people to circlejerk about operating systems
>How many channels do you want to receive in your cabinet ?

5-10 frequencies
Budget: imagine I'm the TempleOS guy with less skills and more money, this needs to exist and I will make it exist

If it sounds like a stupid idea, then it probably is

Incorrect.
The ideas that click and you wish you'd had, aren't always the best ones. Anyone can have those ideas, with similar experiences and education.
The ideas you have to fight to convince people of are the ones, if they succeed, that end up being great

its pointless because FM is a trash broadcast
Im sure you'd be violating some law transmitting FM radio at any level that makes it remotely useful, because its a shit frequency band prone to interference.
