[GreenKeys] Telex Circuit Needed

[Henning DF3OE]

Hello Richard,

see http://teleprinter.net/txp/index2.html

You (KSM) is welcome to join our TelexPhone group. We are emulating 100%
Telex via a phone line.
All what you need is a phone line and a Telex machine with TW39 system
control unit.
So far I know the W.U. telex system in the U.S. worked with TW39 switching
technology.

Actually we are designing a second generation board that has a build in
modem and might
work more reliable also with other telephone systems than the German, even
VoIP.

We already had Larry in Perth Australia connected to our net with great
success until
"something" happened at his end with his phone line after a lightning in his
neighbourhood.

rgds,
henning in germany
