+# Emcomm Tools Configuration for Reticulum
+
+EmComms Tools provides plug-and-play support to reduce the barrier to
+entry for non-technical users. Reticulum is a very powerful tool for
+building user-defined networks. This has the effect of allowing for
+users to create sophisticated, end-to-end encrypted networks that can
+leverage many different transport mediums. While this is powerful, it
+has the potential for introducing complexity for new users. 
+
+This document describes the approach that EmComm Tools takes for
+supporting plug-and-play support with near-zero configuration.  
+
+## Blueprint Configuration Files
+
+EmComm Tools uses a _blueprint_ approach for defining a set of reference
+network configurations to help new users get started.
+
+config.blueprint.permanent-transport-node
+
+## Replacement Tokens
+
+Replacement tokens are defined by `{{TOKEN}}` where `TOKEN` is one of
+the supported tokens below.

+```

+title: Reticulum Setup Notes
+date: 2026-02-13
+updated: 2026-05-11
+author: [The Tech Prepper]
+categories: [reticulum]
+tags: [reticulum]
+---
+
+The following are my personal notes while workthrough an initial evaluation
+of Reticulum for use over packet radio.
+
+1. Install Python 3.
+```
+sudo apt install \
+  python3 \
+  python3-pip \
+  -y
+```
+
+2. Add `~/.local/bin` to your PATH.
+
+3. Install Reticulum as a non-priveleged user.
+```
+python3 -m pip install --user rns
+```
+
+4. Verify that the Reticulum daemon is installed correctly.
+```
+which rnsd
+```
+
+4. Start Reticulum. This will start the service and create an initial
+   configuration file under `.reticulum/config`.
+```
+rnsd
+```
+	
+
+5. Stop the service with `<CTRL>+C`.
+
+6. Edit `~/.reticulum/config` and enable the AX.25 interface by 
+   adding the KISS section below.
+```
+[interfaces]
+
+  # This interface enables communication with other
+  # link-local Reticulum nodes over UDP. It does not
+  # need any functional IP infrastructure like routers
+  # or DHCP servers, but will require that at least link-
+  # local IPv6 is enabled in your operating system, which
+  # should be enabled by default in almost any OS. See
+  # the Reticulum Manual for more configuration options.
+
+  # Default local LAN interface (keep this enabled for testing)
+  [[Default Interface]]
+    type = AutoInterface
+    enabled = No
+
+  [[Packet Radio AX25 KISS]]
+    type = AX25KISSInterface
+    enabled = Yes
+
+    callsign = KT7RUN
+    ssid = 2
+
+    port = /tmp/kisstnc
+    mtu = 256
+```
+
+7. Start Dire Wolf. In EmComm Tools, run `et-mode` and select
+   `bbs-client`.
+
+8. In another terminal, start Reticulum.
+```
+rnsd
+```
+
+If successful, you should see something like the following:
+```
+$ rnsd
+[2026-02-14 12:59:02] [Notice]   Serial port /tmp/kisstnc is now open
+[2026-02-14 12:59:02] [Notice]   Configuring KISS interface parameters...
+[2026-02-14 12:59:02] [Notice]   KISS interface configured
+[2026-02-14 12:59:02] [Notice]   Started rnsd version 1.1.3
+```
+
+## Install a Message App
+
+1. Install NomadNet.
+```
+python3 -m pip install --user nomadnet
+```
+
+2. Start NomadNet.
+```
+nomadnet
+```
+
