the scrambler (voice) acs-2

Another eBay find. One of the ACS2 handsets arrived with a broken PCB, and I am blaming customs for that one.

Luckily, it was a fast repair job.

Before the scrambled audio starts, the two units exchange a short synchronization signal. You can hear the sound exchanged between the units in the video below.

I opened both units to inspect them for further damage beyond the broken PCB.
