Since I own a WinRadio Excalibur this information came via email and I wanted to share it.

Hallo - in the last weeks I had had the opportunity to try out several
software for decoding digital signals, ranging from "free" to beyond 10.000
$. I couched a comparison into an introduction into utility DXing, showing
also some techniques on how to catch short-time transmission by
software-defined radio, or SDRs.

This 50-paged multimedial iBook "Utility DXing - A Primer" can be downloaded
for free at:

There you find also a link to the same book as PDF, readable not only on the
iPad but on every PC and Mac, but lacking videos. Up to now, at least one
example of these videos had been placed on You Tube:

The publication is centered around the new Decoder Krypto500, and contains
numerous comparisons with other software decoders, using hands-on examples
with modes like STANAG4285, GW-FSK/OFDM and PACTOR-I to -III. It has been
written also as an example to discuss the future of publishing test reports
etc. in an easy-to-follow and transparent manner. The iBook has been written
with software "iBooks Author" which easily allows for e.g. integration of
multimedia.

Comments & critics are highly welcomed.
