Ever wondered what signal you're picking up? This page aims to help you determine what you're seeing and what parts it consists of.

What it is Not a clue
Frequency 433.963 MHz
Modulation AM
Details the signal repeated 12 times, it consists of
 marks            :  2.5 ms

 short space      :  2.5 ms
 long space       :  5.0 ms
 extra long space : 10.0 ms 

Assuming the information is in the spaces,

 2.5  = 1
 5.0  = 0
 10.0 = message spacing

then I've picked up the following code:

IMPULS (10621)

What it is Not a clue
Frequency 433.65 MHz (depends on key :S)
Modulation AM
Details the remote has 10 keys, 5 sets (A, B, C, D, E) of (ON, OFF)

the code consists of

 long pulse       :  433 us
 short pulse      :  142 us
 
 short space      :  149 us
 long space       :  439 us
 extra long space : 4500 us

every short pulse is followed by a long space, and viceversa

assuming the information is in the pulses:

 short = 1
 long  = 0
 extra long brake is telegram spacing

then the following codes are observed:

 ON: (A, B, C, D, E)
 1000000000111010101010111 x 14
 1000000000101110101010111 x 13

 1000000000101010101110111 x 19
 
 OFF: (A, B, C, D, E)
 1000000000111010101011101 x 15
 1000000000101110101011101 x 15

                      + |  OFF = (NOT ON)
                        +  NOT OFF = (ON)

when a button is depressed, a few (1-3) of the following messages are sent:

 0010101000101010101000001 (address set to ON-OFF-OFF-OFF-ON)

ELRO ab440r

What it is remote control for plugin lightswitches
Frequency 433.865 MHz
Modulation On Off Keying (OOK)
Details the remote has 8 keys, 4 sets (A, B, C, D) of (ON, OFF)

the code consists of

 long pulse       :   460 us
 short pulse      :  1113 us
 
 short space      :   188 us
 long space       :   838 us
 extra long space : 10000 us

every short pulse is followed by a long space, and viceversa

assuming the information is in the pulses:

 short = 1
 long  = 0
 extra long brake is telegram spacing
