## What is Wifi Rig CTRL?

WifiRigCTRL is a controller app that lets you remotely operate an amateur (ham) radio transceiver from your iPhone or iPad over Wi-Fi.

Two ways to connect:
1. Via Raspberry Pi (Hamlib/FastAPI) — CAT control for a wide range of rigs, plus RX audio, CW, FT8 and APRS
2. Direct CI-V — connect to an IC-705 / IC-9700 on the same Wi-Fi, no Raspberry Pi required for basic operation

■ Features
- Real-time display of RX frequency, mode and signal strength (S-meter)
- Change frequency, mode, TX power, squelch and filter width
- Play received audio through the speaker (with noise reduction)
- PTT ON/OFF and microphone audio transmission
- Wi-Fi PTT (PTT control via external devices such as M5Atom)
- CW decoding (multi-station, up to 5) and CW transmit (presets, WPM control)
- BLE CW keyer support (connect DualKey-BLE / RemoteKeyer-BLE over Bluetooth)
- FT8/FT4 decode and transmit
- APRS beacon transmission (with smartphone GPS)
- Multiple profiles (switch between connection targets)
- API key authentication and remote access over WireGuard VPN

■ What you need (important)
This app does not work on its own. You must have one of the following (your own hardware):
- A set-up Raspberry Pi Zero 2W connected to your radio (Hamlib/FastAPI installed), or
- An IC-705 / IC-9700 (for direct CI-V connection)
Connect it to the same Wi-Fi network as your iPhone.
Raspberry Pi setup instructions and firmware are published on GitHub:
https://github.com/ji1ore/M5CoreHamCAT

■ Who it's for
For licensed amateur radio operators who have a compatible radio setup.

This app contains no ads and no usage tracking. Any information is used only on your device and is never sent to external servers.

What's New in Version 2.32

[Repeater Settings — CI-V Direct Mode]

Long-press the frequency display to open the Repeater Settings sheet.

Offset
- Direction: None / + / -
- Presets: 100 kHz / 600 kHz / 1 MHz / 1.6 MHz / 5 MHz / 7.6 MHz
- Custom offset input also supported

Tone
- Mode: None / TONE (encode only) / TSQL (encode + squelch) / DTCS
