Radio Frequency Reference Sheets | Radio Spectrum Reference
I may have touched on this once before, but wanted to make sure to highlight a few of these great references over at dxzone.com. First up is Known frequencies from .1 to 21200 Mhz. They make notes of what kind of modulation is typically used in the ranges (AM/SSB/FM/etc.) (Text only document with description of the ranges use.)
Links to the US Frequency allocation chart (in pdf format) are on this page. (Available as a wall chart for about $13 US.
There’s also a general web browsable index of radio frequencies at this link. They’re grouped by the type of use.
There are other great frequency references as this dxzone.com page.
