EMC Software

This page gives access to a number of software tools for EMC work.


ICNIRPcalc allows you to calculate the distance people need to stay away from a given antenna, so European exposure limits are not exceeded. The new Version has German, English, French and Swedish language capabilities now and the antenna database has been enlarged. Download here.

QRM estimator

The QRM-Estimator is a small tool to calculate the field strength of a disturbace at a certain distance with respect to the measurement limits spelled out in ECC Recomendation 05(04). It can be used to estimate, if a disturbance from a wire line bould telecommunication application causes an interferance at the amateur’s receiving location, with respect to the limit. A version for Andoid tablet or phone can be downloaded by using the google play store and search for “QRMcalc”, or can be downloaded here.

Another program called RxInterferanceLevel estimates the signal level to be expected in your receiver near a disturbance source operating on the power line.

Noise reporter v 1.0

Anyone who wants to help sustainably stop the decay of the electromagnetic environment, must first consider the level of the electromagnetic interference in relation to the expected level. This is relatively simple using NoiseReporter, which is based on ITU‑R P.372 – 12 as a basis for intended radio reception.

The Essential Requirements as laid out in the EU directive for the immunity of equipment [1] need a measurable reference. Among the ITU Member States for that purpose the ITU‑R P.372 – 12 is known to quantify the man made noise expected in a given environment. [2]. In particular, the immunity tests in harmonised standards presume with their severities a given electromagnetic environment, which refer to the ITU‑R P.372 – 12 as reference.

If you wish to qualify your environment, try NoiseReporter and download here.

Note: This is Version 1.0 and first publication. It is likely, that there are bugs in the software. If you find a bug, please report with detailed description to the author.
