Liz,

I'm probably about to jinx myself but here goes! I'm delighted with both 
Pi's since I paid attention to their power supplies. The ADSB Pi with 
DTV dongle is in its 40th day and the aprs gateway Pi with four port 
USB/RS232 adaptor is in day 36. Both Pi's run headless with Ethernet 
connectivity to the LAN and both operate without a USB hub. It's going 
to be a shame to replace them with the old Acer laptop.
