This type of scrambling was broken by the Germans back in the early 1940's. Read about the Bell Labs A-3 scrambler. It is very similar to MASC. However, MASC probably uses random sub band inversion and it swaps the bands much quicker than the A-3. However, it's the same principles.
NICE! I was able to get a pair of the Motorola 600e's with MASC. The MASC is on and I am not going to even try to switch it off for fear of dumping the key. MASC is a very good analog/digital encryption scheme. I live in the U.S so it was pretty hard to get a pair.
by switichin it off i suppose you mean programming it off?? cause im pretty sure the only ones you need a key loader for are the sabers with DES. otherwise cant you just make up your own key....
COOL! I used to work on these many years ago. Fun times at Marconi Secure Systems :-)

marconi advanced scrambler ..is it using voice inversion

I am surprised they don't have auto-decode of MASC.

No you can hold a side button for 2 seconds to turn it on or off, hold it too long and you dump the key.

That was the old HT600e radios not the MT6000e
