Ideas to create a universal RF scanner.

OOK
on off keying
Every frame seems to start with a large pulse or a large space.
This generates a start condition.
The pulsewitdh is measured and the smallest pulse above the minimal pulsewith is used as base T.
The rest is simply 1T 2T etc.
for example:

433A 66 9340 408 F191519141519191519151515191919191514191515151519191915151519151510

Receiver 433A got 66 pulses after a gap of 9340 uS. a "1" is 408uS.
This signal looks like [[space-len]] encoding.
