Ham Radio Remote Control The IC 2730

Ham Radio Remote Control the Icom IC-2730 Dual Band VHF/UHF 50W Mobile Radio with Simple Ham Radio Remote Software and a Raspberry Pi.

The IC-2730 has a very limited number of CI-V commands. There are just enough commands to remote control the radio.

Simple ham radio remote IC 2730 web app is currently being tested. There is a download available on this page if you're interested. Documentation is currently limited to this page and related project links.

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-2730).
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 192.168.0.1, 192.168.1.1 or 192.168.1.254 or 10.0.0.1
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

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-2730)
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.
Click [ Hang Up ]

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.
If you don't have the selected radio connected to the USB-Serial port, when you click [ Call Radio ], you will get an error message "Unable to Connect to Radio!".
This installation is for LAN access only. See user manual for Internet access.
Access the user manual using your username and password the day after setting up SimpleHRR.
