Crypto Notcher (Oh my god!!)
by Hirotzuko Takahashi
This is the original project of the Crypto Notcher, called "Oh My God!!" from the engineers of Canal Plus.
I have decided to publish this job of mine to oppose the to proliferate some black commerce on the occasion of the new systems of crypto sat-tv giving the possibility to everybody to resolve the problem in definitive way.
The realization, contrarily of the planning, it is not particularly difficult. The CN directly works on the coaxial cable that departs from the LNB and it reaches the decoder, his inside circuit it filters and it converts the wave signal it squares responsible of the crypto of the DVB flow, confusing it and dispersing it to mass, this clever system it allows the signal DVB to come in clear to the receiver as if it was treated of a signal FTA. The system works with any it codifies, present and future and obviously it also eliminates of fact the harmful ECMs.
Code:
Component
Particular attention must be lent L4 to the realization of the spool
for the correct filtration of the component crypted.
CF1 is a ceramic filter, recoverable from OM Transceivers and CB.
L1 = 20 coils on graphite from 0.3cm
L3 = 4 direct coils on coaxial
L4 = 6 coils side 1cm
L5 = 10 coils 0.6cm, 3 coils separate of 2mm
L6 = 4 direct coils on coaxial
The setting is performed by TC1, tuning in to it to have the signal in clear.
Part List
C1 100pF Mylar
C2 1000pF
C3 27pF
TC1 compensator 100pF
CF1 Ceramic filter 455KHz
D1 Diode 1S2473

Please, use your mind, it isn't impossible to make it.
Good Luck and Best Regards.
