Connect the Raspberry Pi to the IC-7300, 7610

  • Plug the USB cable into the Raspberry Pi the other end into the IC-7300, 7610

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, 7610).
  • 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

  • If you have access to the router, login as admin via a browser. The router IP address is usually something like 192.168.0.1, 192.168.1.1 or 192.168.1.254.
  • Look for Attached Devices or Device Name (Raspberry Pi simplehrr) - IP Address
    (something like 192.168.1.8).
  • Write down or copy that IP Address you will need that to activate SimpleHRR.

  • Open a Chrome or Firefox web browser enter the URL:
    https://your-Pi's-IP-address:50000/remote
  • Enter Username (a valid QRZ Callsign).
  • Enter Email address. Optional: Just leave noemail@noemail.com
  • Enter Password (greater then 8 char).
  • Select Radio (IC-7300, 7610).

Read me:
  1. First time boot: takes about 2+ minutes all 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. Port Forwarding required for Internet access.
  3. Access the user manual link using your username and password the day after activating SimpleHRR.
  4. If you already activate SimpleHRR and activate or reactivate another, the password to the user manual link will remain the same!
  5. For security reasons, only Chrome or Firefox browsers are allowed to log in to access the user manual!
  6. Supported Radios:
    Icom IC-7100, IC-7300, IC-7610
    Icom IC-7300, IC-7610 (has been tested)
    Icom IC7100 (has not been tested)
