Khanfar TX v2

Developed by Khanfar Systems

A powerful remote control GUI for rpitx, enabling wireless RF transmission control through SSH.

Features

• Remote SSH connection to Raspberry Pi
• Frequency control (5 KHz to 1500 MHz)
• Multiple transmission modes supported:
  • Tune (Carrier Signal)
  • Chirp (Moving Carrier)
  • Spectrum (JPG Painting)
  • FM RDS (Broadcast)
  • NFM (Narrow Band FM)
  • SSB (Upper Side Band)
  • AM (Amplitude Modulation)
  • FreeDV (Digital Voice)
  • SSTV (Slow Scan TV)
  • POCSAG (Pager Messages)
  • Opera (Special Morse)
  • RTTY (Radioteletype)

Requirements

• Python 3.6 or higher
• Required Python packages:

  pip install paramiko
  pip install tkinter

• Rpitx installed on your Raspberry Pi
• SSH access to your Raspberry Pi

Quick Start Guide

1. Installation

1. Ensure rpitx is installed on your Raspberry Pi
2. Install required Python packages:

   pip install -r requirements.txt

2. Starting the GUI

python rpitx_remote_gui.py

3. Connection Setup

1. Enter your Raspberry Pi's details:
   • Host: IP address (e.g., 192.168.1.100)
   • Username: SSH username
   • Password: SSH password
   • Rpitx Path: Path to rpitx (default: /home/username/rpitx)

4. Using the GUI

Basic Operations

1. Set your desired frequency in MHz
2. Choose a transmission mode
3. Monitor the status indicator
4. Use "Stop Transmission" when needed

Transmission Modes

• Tune: Simple carrier signal
• Chirp: Moving carrier signal
• Spectrum: Transmit images as RF
• FM RDS: FM broadcast with RDS
• NFM: Narrow band FM
• SSB: Upper side band modulation
• AM: Amplitude modulation
• FreeDV: Digital voice
• SSTV: Slow scan television
• POCSAG: Pager messages
• Opera: Special morse mode
• RTTY: Radioteletype

Safety and Best Practices

• Always use appropriate RF filtering
• Follow local RF transmission regulations
• Monitor Raspberry Pi temperature
• Use emergency stop when needed
• Keep proper antenna length for frequency

Troubleshooting

1. Connection Issues

   • Verify SSH access to Raspberry Pi
   • Check network connectivity
   • Confirm correct credentials

2. Transmission Problems

   • Verify rpitx installation
   • Check file permissions
   • Monitor GUI status messages

3. File Upload Issues

   • Ensure sufficient disk space
   • Verify write permissions
   • Check file format compatibility
