ISO single line telephone hybrid

> Anyone have one sitting around collecting dust?

I thought you had an ISDN codec. Most of them make elegant hybrids when
calling POTS lines.

He wants a nice box with a 111C, a loading network, and some attenuators
in it. I have my Heathkit away a couple months ago, otherwise I would have
volunteered it.

There are a lot of commercial hybrids available for cheap right now because
of the digital stuff becoming popular.

Actually, I was thinking more along the lines of a Telos One digital hybrid
for recording separate channels of audio in a phone conversation.

To be honest, the Telus One doesn't give you very much more separation than
a 111C in a box. What it does give you is instant separation without having
to fiddle with the loading controls for each call.

The older analogue hybrids that require manual setup are, as I said, very
cheap right now because everyone is going the digital route. And if you
can spend half a minute tweaking a knob for best rejection (or two knobs
in the case of some of the older ones), they are just as effective.

Orrtronics, formerly Harris-Allied's used guys have shelves of older analogue
hybrids that they can't get rid of most of the time. 800-300-0733.
