The WiNRADiO Telephone Control Interface (WTCI) is ideally
suited for remote surveillance and monitoring of radio signals.
WTCI mounted under a WR-3150e
(front view).
The WTCI works like an auto-answer modem. Upon dialing in, a
pleasant digitized voice invites the user to enter a password.
The unit is designed to work in conjunction with WiNRADiO wideband communications receivers (WR-1550e, WR-3150e, WR3500e and WR-3700e).
Upon successful entry of the password, the user can select from a
large variety of commands. These include simple commands such
as setting frequency and volume, as well as commands performing
scanning, or status reading including signal strength.
The WTCI is connected to the receiver and a standard phone line,
or optionally to a cell-phone. The user can control the receiver
remotely using DTMF (touch-tone) commands, and the WTCI unit
confirms received commands using a digitized voice.
Received audio signals can be listened to by the user in real time,
from any public or private phone.
There is no limit on how far the receiver can be located from the
listener, as long as a standard telephone service exists in both
locations. The WTCI unit is therefore eminently suitable for remote
monitoring of transmitters in civilian as well as government and
military applications.
There are two WTCI models: WTCI-B (basic version) and WTCI-S
(special professional version). The WTCI-B model supports manual
control only, and does not have a provision for a mobile (cellular)
phone connection. The WTCI-S model makes it also possible to
control the receiver using a PC (equipped with a voice modem)
and the WTCInet option.

The WTCInet option is a PC-based software which makes it
possible to network WTCI units using a PC with a voice modem, as
well as add various advanced functions such as real-time audio
recording.
The user interface of the optional WTCInet software is designed
around familiar and intuitive WiNRADiO receiver interfacing
concepts. The control panel resembles the intutitive user interface
of a standard WiNRADiO receiver.
In addition to real-time control by the operator, WTCInet software
makes it possible to automatically monitor, log and record the
audio signal, without supervision.
