WICEN Vic: New Website Atricles

[Mark Dods]

I've uploaded a couple of interesting articles from the "Critical Comms" 
website (http://www.criticalcomms.com.au/) to the WICEN site.

The first is a paper about the current use of HF in general, and digital 
HF in particular:

The second paper addresses an issue we've been aware of for some time; 
the alignment of FM radios for optimum performance with digital signals. 
The new article is at:

A simplified treatment of this topic has been on our web site for some 
time at:
