Here are papers on simulcast systems your colleagues have designed
to successfully implement wide area coverage. The Simulcast Forum
is an annual event, held annually in conjunction with IWCE /
Las Vegas, with an annual APCO supplement. If you have any questions
about a presenter's material, email
us and we will either reply with an answer, or forward your
question to the presenter.
