[Voyage-linux] ECN for ALIX boards

[Edwin Whitelaw]

I have a friend locally who does SBC manufacturing and he's agreed to do 
the soldering for me.  Unfortunately for me I have 7 units already in 
the field with some being a little difficult to get at.  On the other 
hand, they have CM9s or other low powered radios and seem to be working 
fine so I'll probably just mod the ones still here at the shop and of 
course any new ones that come in until they start appearing with the new 
mod from PC Engines itself. 

I received the ECN notice from Dornier himself so it sounded like he 
would be adding those capacitors effective immediately. 

 From the notice:  "Effective: running change, phase in ASAP"

It remains to be seen if that simple modification in fact fixes 
everything.  I know I'm not alone in my desire to take advantage of the 
range and speeds that two 600mw radios can provide on a given link!  Due 
to the present problem, I have a drawer full of XR5s that I will test 
with as soon as I can get my remaining two boards fixed, hopefully this 
week.  I'll load them up with the XR5s and see what happens.  Stay tuned.

As for power supply, I'm using some 12v, 1A units that measure 17+ volts 
with the ALIX powered so I can't see that as an issue.
Regards,

Edwin
