How to minimize the effects of time-delay interference

In this article, we examine ways to minimize TDI’s effects, which will cripple system performance — even when excellent RF coverage exists.

A look at time-delay interference

Does your simulcast radio system seem to exhibit improved range and performance when certain transmitters are turned off? In almost every case, this is an indication of improper system operation and that your system needs on-site optimization.

Your license will be in violation of the FCC Rules and you could be subject to FCC enforcement action, which may include a monetary fine, admonishment or loss of your license.

When accuracy isn’t all

When it comes to radio system measurement, there actually are three other important aspects — precision, reliability and traceability.

The bane of your existence

Radio-frequency interference is something that every radio-system engineer will encounter, sooner or later. In this installment, we begin to explain how it occurs and what to do about it.
