Hardware required

Icom IC-705
micro SD card adapter
micro SD card (8GB class 10 minimum)
Raspberry Pi 4 Model B ( only )
Raspberry Pi 4 Power Supply 2.5A - (3A - 3.5A better)
Cat5 Ethernet cable (connecting Raspberry Pi 4 to LAN)
USB Type A Male to B Male Cable (between Pi & IC-705 )
USB - Bluetooth - 2.4GHz Wireless mouse with a scroll wheel
Computer with an SD slot (or an appropriate SD card adapter)

Download and Install the Image on the microSD card

This image contains everything you need to get up and running quickly.
- Download: SimpleHRR v0.2.1-f
  Sorry for the inconvenience, you might have to close the Dropbox tab when the download has finished.
- Windows: To extract the image double-click the .zip file then click Extract All.
Insert the microSD card into the computer's SD card slot use the SD card adapter if needed.
Next, flash the .img file to the microSD card with your favorite image writer. There are various image writer you can use, example Etcher - Raspberry Pi Imager for Linux, macOS or Windows.
Now remove the flashed microSD from the computer, keep it in a save place will insert it into the Raspberry Pi 4 later.

Prepare the IC-705 for Remote Operation

Firmware version should be at least 1.27 or higher.

Connect the Raspberry Pi 4 to the IC-705

Plug the USB cable into the Raspberry Pi 4 the other end into the IC-705

Connect the Raspberry Pi 4 to Network

Plug the Cat5 cable into the Raspberry Pi 4 Ethernet port the other end to the LAN.

Booting the Raspberry Pi 4 for the First Time

Insert the flashed microSD card into the Raspberry Pi 4 microSD slot.
Power ON the Radio (e.g IC-705).
Power ON the Raspberry Pi 4.
Wait for the Pi to boot up - the green LED should stop flashing when it's finished!.

Get the Raspberry Pi 4 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.

Set up Simple Ham Radio Remote on your Raspberry Pi 4

Turn the radio ON
Open a Chrome or Firefox web browser enter the URL:
https://your-Pi's-IP-address:50000/remote
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-705)
Select Dev ACM: (/dev/ttyACM0)
Click [ Activate ]
Verify the information is correct Click [ OK ]
Wait 1 minute for Raspberry Pi 4 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.

That's it.

Read me:

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.
This installation is for LAN access only. See user manual for Internet access.
Access the user manual link using your username and password the day after activating SimpleHRR.
If you already activate SimpleHRR and activate or reactivate another, the password to the user manual link will remain the same!
For security reasons, only Chrome or Firefox browsers are allowed to log in to access the user manual!
Supported Radios:
IC-7300, IC-7610, IC-705
Icom IC-7300, IC-7610, IC-705 (have been tested)
