Capturing Data From 2.4GHz Carrier?

[want2learn]

How do I go about capturing and storing a data stream from a 2.4GHz carrier?

There's a bit of equipment at work, the manufacturer will only supply 2 remotes per device. This is a royal pain since there are about 5-6 of us that need remotes. We've tried loads of times to get more, even told them one was broken but they wont replace it until we send the defective remote back 
There are only 4 buttons- Left, Right, Forward, Back.

I want to see if i can build a couple of remotes myself, a colleague has said the fuse bits will probably be burned to stop me simply using their software so this is out (not that i would actually try to get their software  )

I would've tried google but really I have no idea what I need here!

EDIT:- I should probably have pointed out that I'll have to do this without an oscope as I wont be able to do it at work

How do I go about capturing and storing a data stream from a 2.4GHz carrier?

What format is it transmitted? What does the receiver interpret the data as? bps?

Sorry admin, I don't know.
I know this would be soooooo much easier with a scope but for the forseeable future it aint gonna happen .

Wait . . . so you are asking how to capture data, but you have no idea what the data is or format it is in?

Ok better question . . . what device is transmitting the data?

[want2learn]

Yeah sorry, I know.
The device sending the data is a hand held remote, it has 4 buttons as stated previously. The receiving device could be thought of as a pick and place with manual override (It's similar, I've been told if I'm going to pursue this outside work then I can't give out the machine or manufacturer details.)

Perhaps remote chasing will have to do for now. I knew this would be a pain, just wanted pointing in the right direction

Here is an idea:

Make your own RF remote controls with 4 buttons
Those RF remote control talk to a receiver which switches on transistors which in turn "press" the buttons on the real remotes

So basically like this:
4 DIY remotes ( make them using RF modules or plain old R/C cars)
DIY Remotes talk to a DIY receiver
DIY receiver controls 'real' remote with transistors
Everyone is happy.

DIY = do it yourself, means you made it from scratch

I don't know if you really can capture any data, in any format..... but some
modules from Cypress, can do a lot of things...
Check the cywm6935, note that they need a very clean power supply and that
they are a hell to program and operate.... Believe me!!!!

Frequency sniffer comes to mind

I like erics idea of making a couple of your own remotes and using those to control your own receiver that in turn pushes the buttons. Perhaps using servos or something. Maybe even a really really tiny 3 axis CNC machine that just pushes buttons

Thanks for the suggestion Eric. Seems like it will be the easiest way to go.
I'll run it past my colleagues and see how it goes.

Just goes to show that a little outside help and a bit of laterall thinking can go a long way.

Big thanks to all
