<-- Yeh, I don't know why HP spec' these to require a 3 or 4A supply.  I 
power mine directly off the station power supply (~ 13.8VDC) - measured 
quiescent current was ~ 650mA (it's been a while, so don't hold me to 
that folks!).  IIRC, max current was around 950mA or so.  I generally 
fuse mine with a 1.5A fuse.

One thing that I forgot to mention in my previous note - I did try one 
of these in a full-duplex bench-test / using chan-usbradio (i.e., using 
DSP) - don't go there! - the HP does not have the "sllab" for a 
full-duplex setup.

The other caveat is that I have only ever run one node with chan_simpleusb.

One other tid-bit.... one of my FREE STAR* guys in the UK, told me that 
he was able to take a Wyse terminal and convert that in the same fashion 
as described for the HP.  The last time I checked my local off-lease 
equipment supplier, they had a truck load of Wyse terminals for $10 a piece!
