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.
