[arm-allstar] 3 nodes on 1 pi

[Dave Petrie]

Just throwing out my thoughts, if you add up what it cost for the
enclosure, metal would be better at a repeater site, and the sd card and
the power supplies and sound card to attach a repeater, times 3 repeaters
at a site, you far exceed the cost of a raspberry pi 3 b plus which will
handle 3 nodes with no problem. One of the repeater sites I been helping
with for the last three years, has internet via microwave, Allstar/Echolink
is a pseudo node so it can be isolated if need be, a UHF repeater on the
second node which we call the hub node, that will be used for RF linking if
we ever lose the microwave, and the third node is a VHF repeater. The
repeaters are 100w Motorola MTR2000 and there is a 1000 watt paging company
at the site along with lots more stuff and we haven't seen any real
challenges. I modified the sound cards and my friends installed everything.
So far it's working great. There are three other sites that link in with
the same setup and me most of the time via the Internet.
Have a look at some of my documents in my dropbox. I like the Hamvoip
software and how nice it is to be able to get help from this forum. IT's
all about having fun with the hobby and helping each other.
