With the closure of Monitoring Times, I've started to publish back issues of my monthly Digital Digest column on Amazon Kindle. These ebooks can be read on just about any desktop or mobile platform and each annual compilation runs to around 60 pages covering embassy, military, commercial, intelligence and humanitarian HF users, their frequencies, operating habits, messages and how to decode them using free and commercial software packages. If you are at all interested in figuring out how these kinds of stations work, where they live on the dial, or want to get going with HF utility listening in general, you'll find these books an informative read.
