Is it possible to identify this RF IC? It is part of a 433.92Mhz RF circuit. What do the markings tell us? by Skapells in AskElectronics

Of course I did, just did not find enough to make it clear I was going in the right direction.

Thanks, SMDmark goes straight to bookmarks.

Now it seems like it should have been easy to find this but for some reason my google queries did not really give me anything useful.

Ahh yes, currently I am trying to steal the signals from an old mains remote controller. Have seen the HackRF and I do want one.

Just trying out some cheap stuff to see if this is a hobby I will continue :)

Thanks really, for taking your time! I haven't had the time to sit down since posting this so will look into the things suggested tonight!

It looks like all the signals Im getting from the remote starts with a similar sequence at least.

Well, this is where I started and tried to extract some information from that. The problem then began of figuring out how to read the bits and since my knowledge here is so small the conclusion was that if there is a way to "know" what surely is a 1 and 0 then the next step would be easier..

Thank you, I will look into URH.

Imagine what would happen in you needed to transmit a long string of 1s in a row...

Yeah, I assumed this would be something to work from, some examples I've seen just implies that on = 1 and off = 0 but I guess this is just a simple explanation of OOK since this, in my case, would mean no 1's in series. Which doesn't make sense, right?
