[OZAPRS] hardware suggestions

[Ben Weber]

If you're wanting bullet-proof, I'd go with the WX3in1. Each
additional layer of complexity adds additional points of failure -
running an operating system, writing your own code, etc. My 3in1 sits
on a battery and has been up for 3 months without issue, and prior to
me removing power to make some cabling changes it was over 9. Granted
the modem/router would still require an OS - DD-WRT or OpenWRT would
be the go - at least if it were to fail you would still have a
functional digi. The digi sets in the shed away from the house and
runs over a flakey wifi link, every time the link drops and comes back
up the 3in1 continues along as normal - 'it just works'.
