CWID-1 Repeater/Beacon controller

CWID-1 repeater/beacon controller

Sorry - SOLD OUT!

The CWID-1 Repeater/Beacon Controller is a small (5cm x 4cm) yet powerful microprocessor controlled unit suitable for use either as a Repeater or a Beacon controller. All functions of the controller are set up using a special programming box (CWID-PROG) and a PC running a Windows programme. The unit is supplied pre-programmed to the customers requirements.

Repeater Mode

When used in the Repeater mode the CWID-1 can transmit an ident of up to 48 characters at a speed of between 5 and 30 wpm. The time between idents can be programmed to be from 10 seconds to 30 minutes in 10 second increments and the ident can be programmed to be suppressed when the repeater is idle. An anti-kerchunk timer is built into the software as is a time out timer and a hold (tail) timer. A courtesy tone (Roger Beep) is available as an option.

Beacon Mode

When used in the Beacon mode the CWID-1 can transmit an ident of up to 48 characters at a speed of between 5 and 30 wpm and can be programmed to give a continuous tone/carrier between idents if required.

Jenal Communications design and manufacture a wide range of radio related devices including units which use the standard HF selcall and telcall signalling as used by Barrett, Codan, Icom and Q-Mac. Thousands of these products are being used all around the world by Governments, NGOs, Commercial organisations and Amateur Radio operators. We also manufacture a number of devices which use the common DTMF (or touchtone) signalling system.
