Bill recommends the Signal Identification Wiki

Many thanks to SWLing Post reader, Bill, who shares a link to this Signal Identification Guide:

http://www.sigidwiki.com/wiki/Signal_Identification_Guide

Curious if any readers have been using this guide-seems like a convenient resource to ID those numerous signals on the bands. Entries show what each signal looks like on a spectrum waterfall display and provides audio clips.

Thanks for the tip, Bill!
