  • Marconi Advanced Scrambler Code

  • All the forces use Airwave now, this is old

    Decrypting Airwave = Hell Will Freeze over

  • Thats why there out there for sale now, still a quality radio with good encryption! Airwave is a nightmare as any copper! ;-) well im happy with my sets.. anyone else using MASC on here?

  • You are correct that is plain 5 tine, the audio in the clip isnt MASC (that was just to show mmy MASC ones off) but I can do you all an encrypted clip if you all want to hear them? The radios came to me with four matching keys, and I then copied them over into my other units that had different keys :-) yeahhhhhhh now they all talk in MASC together!!

see all

  • were you actually listening to the police

  • do you know how to get into software when sat in prompt

  • how much for one?

  • MASC cannot be attacked like an inversion based scrambler.

    It is a 5-band scrambler and the unauthorized listener would need to be able to locate properly at least the first two sub bands to hear the message (300-1200Hz).

    If random sub band inversion is also used the sub band would also have to be undone.

  • MASC is a 5 band splitter with inversion. In other words the voice is filtered off into five bands of apprx. 500Hz each and then the sub bands are swooped around at a rate of 10 or more times per second. Due to the characteristics of voice, n band scramblers only have a limited number of good codes, usually around 11. Because of this I am sure MASC also randomly inverts some of the sub bands.

  • can u talk on them or is it a scanner or something like thAT

  • vhf or 800?

  • where yall at
