Features

Dual-Radio Audio & SO2R

Stereo RX with two mix modes (L/R per radio or clone-opposite into both ears). 16-bit audio with selectable sample rates (11.025 / 22.05 / 44.1 kHz) and smooth TX level control. Built for contest-grade CW and SSB. Fully compliant with OTRSP protocol that is implemented on all major contest loggers (eg: DXLog, N1MM etc.)

CAT over TCP ×2

Two independent, transparent CAT bridges with selectable baud rates (9600–115200). Each bridge runs on its own TCP port and accepts a single client for predictable, glitch-free and clean remote tuning and rig control.

Remote PTT with Safeties

PTT via dedicated inputs, via UDP control or via CAT from your contest logging software. A built-in watchdog returns to RX after a configurable timeout to prevent the PTT being stuck in case of network errors and/or disconnects. Physical link monitoring can also force PTT lines to disengage and transfer the transceiver(s) to receive mode if connectivity drops.

On-Device Web Config

Configure everything locally—IP, ports, sample rate, mix mode, TX volume, CAT and keyer bridges, station ID. No cloud dependency. Use on your LAN or expose securely through a VPN/tunnel. Your data, Your stream!

Integrated CW Keyer

TCP-accessible keyer for low-latency CW from your logging software. Keeps timing tight while you operate remotely in SO1R or SO2R scenarios.

How It Works

1

Connect your rig audio (RX/TX), CAT, and PTT. Plug the unit into your LAN. We are going to provide cables interface for all major transceiver manufacturers or we can assist you on building yours.

2

Open the built-in web page to set IP/ports, sample rate, mix mode, CAT baud and ports, and (optionally) the keyer - there are many other useful options that are waitinf for you to discover!

3

Use the provided application (headless) or one of the supported streaming receive applications (VLC) to receive the stream directly. Using the RiG2CasT application on the other hand, would open the full potential of our solution. Operate from anywhere! Remote ham-radio done right!

Tech Highlights

Audio Path

UDP stereo RX stream out; UDP mono TX stream in (routed to Left for TX2 or Right for TX1). 16-bit samples, small frame size for low latency, and per-TX volume control.

SO2R Mixing

Two modes: Normal (each radio to its own ear) or Clone Opposite (active receiver in both ears when you transmit on the other). Or you can choose to be 100% compliant with OTRSP protocol and act like an SO2R routing box.

Network Footprint

One tiny web server + three UDP ports (RX / TX audio / control). Up to three TCP services (CAT1, CAT2, Keyer). One client per TCP service.

Safety & Status

TX watchdog - auto-return to RX after a configurable timeout or in case the netwrk link is lost. Ethernet link monitor with recovery/reboot. Front OLED shows IP, MAC, firmware, uptime, and general status.

Specs at a Glance

Audio

16-bit; 11.025 / 22.05 / 44.1 kHz sample rates. Stereo RX over UDP; mono TX over UDP. Selectable RX mix mode; TX volume 0–255.

Control

UDP control commands: TX1, TX2, RX, MIX0, MIX1. Configurable TX timeout (default 10 s). Remote PTT inputs available.

CAT Bridges

Two independent TCP ports; selectable baud 9600–115200; transparent serial passthrough. One client per port.

Keyer Bridge (Optional)

1200-baud software serial to TCP. One client. Keeps CW timing on the external keyer controller.

Networking

Static IP with gateway, DNS, subnet. Unicast target or automatic broadcast for RX audio. No cloud dependencies.

Web Configuration

All settings on device: network, ports, sample rate, mix mode, CAT, keyer, station ID. “Save & Reboot” from the page.

Security & Remote Access

1

Designed for LAN first. For internet use, place the unit behind a VPN (e.g., WireGuard/OpenVPN) or tunnel. Avoid exposing raw UDP/TCP ports directly to the public internet.

2

No cloud. All configuration is local; your audio and data stay under your control - RiG2CasT proudly states that WE DO NOT COLLECT any data.

3

One client per service. Each TCP bridge accepts a single client to keep things predictable during contests and remote sessions.

FAQ

Is audio latency low enough for CW?

Yes — the system uses small audio frames and 16-bit samples over UDP to keep latency low on a typical LAN. End-to-end delay depends on your network path and client.

Does it encrypt traffic?

No. For internet use, run it behind a VPN or a secure tunnel. On a private LAN you can use it directly.

Which rigs are supported?

Any radio that speaks standard CAT over a serial interface - our solution is taking care of the proper level-shifting of the serial data. The bridges are transparent and fault tolerant

Can multiple users connect?

Each TCP service (CAT1, CAT2, Keyer) accepts a single client by design to prevent any type of accidents. UDP point-to-point or broadcast for RX if you enable it - in other words multiple RX stations can exists on your lan and listen to the traffic without any suplimentary overhead or delay.
