[arm-allstar] node building

Aloha Doug, Dave,
I really appreciate the feedback. It really helps me to get my brain 
wrapped around the workings of this neat little box . You guys always 
give great explanations that even a bonehead like me can understand.  It 
makes me want to learn more and that's a good thing. I'm not afraid to 
jump in and it has allowed me the opportunity to share this little box 
with others, some who know a lot more than I do but who where not even 
aware that this project existed.

  I have 5 BBB's and big plans for them. 1 Rev B and the rest Rev C. The 
Rev B is on a simplex node. I also succeeded in getting a Rev C on my 
MTR2000 Repeater without too much grief and it works great. These BBB's 
replaced some power sucking Dell Optiplex SX280's. (I had a $400+ 
electric bill last month)

  I love the voice announcement feature and how easy it is to generate 
them. Now if I can figure out how to make Allison pronounce Hawaiian 
words, I'll be in fat city. Actually I went to Allison's web page and 
she did some Hawaiian voices for Hawaiian Telcom. I'm afraid she's going 
to want a pretty penny to add them to my sound library though.  But I 
digress!
