This handheld, battery-operated receiver can be utilized in the field to estimate signal intensities of broadcast radio stations. Though not a calibrated measurement device, it displays relative signal intensity in dbu, which can be used for rough translation to millivolts per meter (mV/m) in a given frequency range using an included correlation chart.

It is also useful for measuring AM-band noise before station installation to determine the quietest frequency on which to broadcast. AM signal intensity is displayed as a two-digit read-out on the lighted front panel LCD display. Batteries are included and pre-inserted, so the unit powers up on-band and ready to operate. Included are illustrated instructions from us detailing procedures for measuring AM signals and AM-band noise.

The SMR Receiver is the first device of its kind capable of measuring and displaying AM signal levels with a useful level of precision.

Our project manager Tom Coviak explains it this way: "The SMR Receiver provides a digital LCD readout that correlates reliably to scientific measurement equipment…for about one-hundredth the price."

Further, Tom recommends, "It’s important to have a means of monitoring, not only to make sure your station complies with FCC limits but also so you can spot adverse changes in your signal that could point to equipment concerns within your station or its environment.”

Issues involving an antenna system, for example, are much less expensive to correct sooner than later, since they can affect electronic components downstream.

Coviak advises, “Now every operator can afford such a receiver, and it should be part of the basic toolkit for their station.”

We provide SMR Receivers with all new radio station packages; and they can be obtained separately, as well. Email us to learn more.
