     Menu -> SET -> Function ->
  1. Time-Out Timer (CI-V): ON - 3min

Connect the Raspberry Pi to the IC-7300

  • Plug the USB cable into the Raspberry Pi the other end into the IC-7300

Connect the Raspberry Pi to Network

  • Plug the Cat5 cable into the Raspberry Pi Ethernet port the other end to the LAN.

Booting the Raspberry Pi for the First Time

  • Insert the flashed microSD card into the Raspberry Pi microSD slot.
  • Power ON the Radio (e.g IC-7300).
  • Power ON the Raspberry Pi.
  • Wait for the Pi to boot up - the green LED should stop flashing when it's finished!.

Get the Raspberry Pi IP Address

  • Open a browser and Log in to your router as admin. The router IP address is usually something like, or or
  • Find Attached Devices -> Device Name (Raspberry Pi simplehrr) - IP Address
    (something like 192.168.x.x or 10.x.x.x).
  • Write down or copy the corresponds IP Address you will need that to set up Simple Ham Radio Remote.

Set up Simple Ham Radio Remote on your Raspberry Pi

  • Open a Chrome or Firefox web browser enter the URL:
  • Enter Username: Ham Radio Callsign (confirmed on QRZ.com)
  • Enter Email address: Optional: Just leave noemail@noemail.com
  • Enter Password: (greater then 8 char)
  • Select Radio: (IC-7300)
  • Select Dev USB: (/dev/ttyUSB0)
  • Click [ Activate ]
  • Verify the information is correct Click [ OK ]
  • Wait 1 minute for Raspberry Pi to reboot.
  • Click [ OK ]
  • Enter Username (your Callsign)
  • Enter Password (your Password)
  • Click [ Sign in ]
  • Click [ Call Radio ] when it turns green.
    Be patient it takes a little longer to turn green on a first time install.
  • Logout:
  • Click [ Hang Up ]

That's it.

Read me:
  1. The first boot takes about 2+ minutes because all SimpleHRR prerequisites are installed during the first boot. Wait 2 minutes, then start checking https://your-Pi's-IP-address:50000/remote.
  2. This installation is for LAN access only. See user manual for Internet access.
  3. Access the user manual using your username and password the day after setting up SimpleHRR.
  4. Simple Ham Radio Remote supports most Icom CI-V, Yaesu CAT controlled HF transceivers.
