| 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: 000000000111111110110011000011000000 |

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)
