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 and a section on broadcast related filters. See also the Broadcast Tools site for filter design, power combiners and microwave topics

A new section on Propagation analysis has been added to the MISC web site (click the Misc site button above, Misc tools, Propagation). There you will find propagation various calculators based upon the Friis and Eglis models. Good for those point to point links. There are poin to point links using Langley-Rice, Eglis, Friss models, great circle routing. There have been tweeks to the parallel coupled filter designer and the multistep Wilkinson analyser. Help is needed on choosing the next filter designs to be converted to Web format. I have old C / Fortran programs for capacitive gap, ring resonator, waveguide iris, some specialised combline designs. Opinions?
