If you like chasing a true radio mystery then I have just the thing for you. Over on my Btown Monitoring Post Blog are some interesting post from my good friend Sam in Europe regarding several HF ALE networks, including an Arab Voice/ALE network. How about taking a look and if you have some insight, I would really appreciate some email. I am sure a few of you intel types who read these pages might enjoy a good challenge.
Specific links are included below for the various articles I have posted.
