If you work on the Technical Side of the Radio Broadcast Industry, this is your gateway to the hardware of your profession. There are articles on FM transmitters, RDS and stereo encoders, SNMP managements systems, lumped filters, microwave filters, microwave couplers, combiners, Longley Rice propagation analysis.
See WEB SITE DETAILS above for a more complete description of each web site.

The site dedicated to the Longley Rice equation for the analysis of transmission links (STL) has now been expanded to include more of the world There are now more African countries to a few degrees north of the equator. A swath of Asia is include. Japan is still pending There is a reduced scale broadcast analysis for a fixed set of broadcast radius. Still some optimisation to do and incorporate the a set of model antennas.
