-Prebuilt `.deb` packages for **chan_svx**, an Asterisk channel driver for
+**chan_svx** is an Asterisk channel driver for **AllStarLink 3** that connects directly to a **SvxLink SVXReflector**.
-AllStarLink 3 (app_rpt) that speaks the SvxLink **SVXReflector** protocol
-directly — no USRP hop, single Opus transcode.
 
-Source code: private. Bug reports: **bjorne@sa7aux.se**.
+Unlike traditional solutions that rely on a USRP bridge, `chan_svx` speaks the SVXReflector protocol natively, providing:
 
-## Which package?
+- Lower latency
+- Simpler system architecture
+- A single Opus transcoding step
+- Reduced CPU and memory usage
+- Direct integration with `app_rpt`
 
-Pick by your OS (Debian codename) and CPU architecture. Check with
+This allows SVXReflector talk groups to be used directly from AllStarLink without an intermediate USRP connection.
-`. /etc/os-release; echo $VERSION_CODENAME` and `dpkg --print-architecture`.

+## Features
-|---|---|
-| Debian 13 **trixie**, x86-64 | `debs/asl3-chan-svx_0.2.4~trixie_amd64.deb` |
-| Debian 13 **trixie**, arm64 (Raspberry Pi OS trixie, Pi 3/4/5) | `debs/asl3-chan-svx_0.2.4~trixie_arm64.deb` |

-64-bit only. Requires AllStarLink 3 (`asl3-asterisk`) already installed —
+- Native SVXReflector connectivity
-the package must match that exact release, so use the deb for your OS.
+- Direct integration with AllStarLink 3 (`app_rpt`)
+- SVXReflector v2 protocol support (HMAC-SHA1)
+- Configurable jitter buffer
+- Adjustable RX/TX gain
+- Optional RX/TX AGC
+- Support for x86-64 and ARM64 (Raspberry Pi)
 
-## Install
+Source code is private.
+
+Bug reports and support requests: **bjorne@sa7aux.se**
+
+## Requirements
+
+- Debian 12 (Bookworm) or Debian 13 (Trixie)
+- AllStarLink 3 (`asl3-asterisk`) already installed
+- Access credentials for an SVXReflector
+
+## Download
+
+Clone the repository:
 
 ```sh
-sudo apt install ./debs/asl3-chan-svx_0.2.4~<os>_<arch>.deb
+git clone https://github.com/<your-repository>/asl3-chan-svx.git
+cd asl3-chan-svx
 ```
 
-Dependencies (`asl3-asterisk`, `libopus0`, `libssl3`) resolve automatically.
+## Choose the Correct Package
 
-Then, to enable it:
+Verify your Debian release:
 
-1. Create `/etc/asterisk/svx.conf` (host, port, login, password, callsign, tg —
+```sh
-   plus optional `tx_hold`, `jitter`, `rx_gain`/`tx_gain`, `rx_agc`/`tx_agc`).
+. /etc/os-release
-2. Uncomment `load = chan_svx.so` in `/etc/asterisk/modules.conf`.
+echo $VERSION_CODENAME
-3. Set `rxchannel = SVX/<section>` on your node in `/etc/asterisk/rpt.conf`.
+```
-4. `sudo asterisk -rx "core restart now"` then `sudo asterisk -rx "svx show"`.
 
-`postinst` prints these steps, and a full walkthrough ships in
+Verify your CPU architecture:
-`/usr/share/doc/asl3-chan-svx/INSTALL.md`.
+
+```sh
+dpkg --print-architecture

+| Platform | Package |
+|-----------|----------|
+| Debian 13 (Trixie), x86-64 | `debs/asl3-chan-svx_0.3.2~trixie_amd64.deb` |
+| Debian 13 (Trixie), ARM64 (Raspberry Pi OS Trixie) | `debs/asl3-chan-svx_0.3.2~trixie_arm64.deb` |
+| Debian 12 (Bookworm), x86-64 | `debs/asl3-chan-svx_0.3.2~bookworm_amd64.deb` |
+| Debian 12 (Bookworm), ARM64 (Raspberry Pi OS Bookworm) | `debs/asl3-chan-svx_0.3.2~bookworm_arm64.deb` |
+
+Only 64-bit platforms are supported.
+
+## Installation
+
+Install the package that matches your operating system and architecture:
+
+```sh
+sudo apt install ./debs/asl3-chan-svx_0.3.2~<os>_<arch>.deb
+```
+
+Required dependencies (`asl3-asterisk`, `libopus0`, and `libssl3`) will be installed automatically.
+
+## Configuration
+
+### 1. Create svx.conf
+
+Create `/etc/asterisk/svx.conf` and configure:
+
+- Reflector hostname
+- Port
+- Callsign
+- Password
+- Talk group
+
+Optional settings:
+
+- `tx_hold`
+- `jitter`
+- `rx_gain`
+- `tx_gain`
+- `rx_agc`
+- `tx_agc`
+
+### 2. Enable the Channel Driver
+
+Edit `/etc/asterisk/modules.conf` and enable the module:
+
+```ini
+load = chan_svx.so
+```
+
+If a line already exists as:
+
+```ini
+;load = chan_svx.so
+```
+
+remove the leading semicolon.
+
+### 3. Configure app_rpt
+
+Edit `/etc/asterisk/rpt.conf` and set:
+
+```ini
+rxchannel = SVX/<section>
+```
+
+where `<section>` matches the section name in `svx.conf`.
+
+### 4. Restart Asterisk
+
+```sh
+sudo asterisk -rx "core restart now"
+```
+
+### 5. Verify Operation
+
+Check the driver status:
+
+```sh
+sudo asterisk -rx "svx show"
+```
+
+A successful connection will display reflector and talk group information.
+
+## Documentation
+
+A complete installation and configuration guide is included with the package:
+
+```text
+/usr/share/doc/asl3-chan-svx/INSTALL.md
+```
+
+The package post-install script (`postinst`) also displays the required setup steps after installation.
+
+## Compatibility
+
+`chan_svx` implements the SVXReflector v2 protocol (HMAC-SHA1).
+
+Reflectors that provide v2 compatibility can be used even if their SvxLink nodes normally operate using v3/TLS.
 
 ## Notes
 
-- Reflector logins are used **upper-case** (SvxReflector validates the callsign).
+- Reflector logins must use an **upper-case callsign**.
-- Speaks SVXReflector **v2** (HMAC-SHA1). Reflectors that also offer v2 work even
+- SVXReflector validates callsigns case-sensitively.
-  if their nodes normally use v3/TLS.
+- The package version should match the installed AllStarLink 3 release.
