Lee,
As you say our installations were fairly similar. One can only speculate
on the reliability situation.
I'm just minutes away from 14 days uptime and that's a record for the Pi
and aprs. The adsb Pi is heading for 17 days.
Dixprs is using around 33% of the cpu and system load is around 0.9 all
the time, possibly due to the USB/RS232 driving three configured serial
ports, two of which are driving active TNC's.
I'm now keen to see what sort of up time I can get from the Pi.
In the fullness of time I want to add an external HDD for storage
purposes but I'll likely move everything (aprs and adsb) to an old Acer
laptop rather than mess about with powered hubs again. The old Acer sits
at about 35W input power unless it works hard, and I can live with that
for a battery-backed 12v system.

Thanks Ray. My unstable setup was very similar to yours - Dixprs as the
IGate and AX25 networking on the Raspbian/Wheezy distro. It also included
a powered USB hub for the USB to serial adapter, USB enclosure with IDE
hard drive, and (sometimes) a keyboard & mouse. In theory I didn't need
the wired hub because the USB drive enclosure was powered, but I had
started with a laptop hard drive in a smaller HD enclosure that did need
the powered hub, so I just stuck with it, anyway. I was not using WiFi -
at least not directly. The wired Ethernet port was connected to a wireless
access point configured in client mode, so the AP handled the wireless
connection to the router. 10 days was very typical before a crash. In my
case it was not just networking - pretty much everything - had no access to
the Pi once it crashed.
My current setup, however has not changed from the above other than to run
Xastir as the IGate instead of Dixprs. It has now run for 20 days and
counting. I started out using a universal phone charger rated at
5.5v/800mA. Then I moved up to an "Amazon Basics" unit rated at
5.5v/2100mA, but nothing changed. Only changing the software has had an
impact.
