Utility Planet is the official blog for the column of the same name in The Spectrum Monitor. It replaces Utility World in the discontinued Monitoring Times magazine. Utilities are all VLF/LF/MF/HF (and sometimes low-band VHF) radio communications except broadcasting, CB, and non-emergency amateur. If you understood the last sentence, you know enough to read this blog.
