HBO decoders

[pav]

Hi all,
I am looking for information about HBO decoders - schematics, info, anything

[toltec]

Here, local company Evrocom uses SAWDEC by ARCOM. They transmit at 2 frequencies. I have an original encoder and a Romanian do-it-yourself one. The encoding is done through adding interfering signal at 230 KHz, before the video carrier. Removing is done by very narrow band SAW filter.
You may find some info at the ARCOM web site
