[arm-allstar] 3 nodes on 1 pi

[David McGough]

Hi Jason,

An RPi3B or RPi3B+ should support all 3 nodes. I believe the RPi4B issue 
is also resolved in recent boards, hardware revision 1.2 or later.

Also, the new RPi Zero 2 W is an excellent choice for single nodes, giving 
all the functionality as the RPi3A+, at least as needed for HamVoIP use.

Personally, for co-located repeaters and node radios, I still recommend
only a single node per RPi, even though the software and RPi hardware will
support more than one radio.  This configuration makes isolating the
grounds, audio and control signals between radios trivial, helping to
solve potential audio, RF and even lightning surge issues.

Pishop currently has some RPiZ2W boards in stock for $15 each.  Also,
they're available at MicroCenter, etc.  Here is the PiShop link:

To add a third node to an existing system, you'll need to add a node
stanza in the rpt.conf file and a device stanza in the simpleusb.conf
file.  To support in-coming connections to the node instance, you'll need
to add the node number as an extension to the dialplan [radio-secure]
stanza, in the extensions.conf file.  Then, restart asterisk and setup the
new node radio config using simpleusb-tune-menu.


Merry Christmas!
