Remote Control Your Ham Radio Station Through WiFi Hotspot

This post is about how to ham radio remote control your amateur ham radio station without a Router or Local Area Network through a dedicated WiFi Hotspot.

Ham radio remote control your amateur ham radio station from Desktop PC, Laptop, Android phone through a web browser around the QTH via a RPi Hotspot in the Ham shack without a Router or a Local Area Network.

*If you're going to use the Simple ham radio remote web app, install it first, after the installation, login to the Raspberry Pi and install "RPi Hotspot".

*Raspberry Pi (RPi)

A versatile single-board computers made by the Raspberry Pi Foundation.

Remote control Amateur (Ham) radio transceiver using a Raspberry Pi (RPi)

We are not going to do anything special this has already bin done very well here. We are just going to follow the instructions there to install a Hotspot on the Raspberry Pi.

Prerequisites

SSH into the Raspberry Pi.

                1. Update OS

                sudo apt-get update --allow-releaseinfo-change

                2. Add country to wpa_supplicant.conf

                sudo raspi-config nonint do_wifi_country [your country code]

                Example -> sudo raspi-config nonint do_wifi_country US

                3. Make a new folder

                mkdir wifi-hotspot

                4. Change directory

                cd wifi-hotspot

                5. Download the files

                curl "https://www.raspberryconnect.com/images/hsinstaller/Autohotspot-Setup.tar.xz" -o
                AutoHotspot-Setup.tar.xz

                6. Extract the files

                tar -xvJf AutoHotspot-Setup.tar.xz

                7. Reboot the Raspberry Pi

                sudo reboot

                8. SSH into the Raspberry Pi.

                9. Change directory

                cd wifi-hotspot

                10. Change directory

                cd Autohotspot

                11. Start the RPi Hotspot

                sudo ./autohotspot-setup.sh

We have launched the AutoHotspot script

From the Menu Select

Select the best option for your needs. I selected 1

1 = Install Autohotspot with Internet for Connected Devices

Be sure to write down the following:

8 = Exit
sudo reboot

Give the Raspberry Pi a minute to boot

Grab your PC Laptop Android phone Setup Wifi

                Seach For and Select

                RPiHotspot - Password - 1234567890

                Once connected

                If you have installed the SimpleHRR ham radio remote web app.

                To access the amateur ham radio transceiver remotely.

                Lauch Chrome or Firefox browser

                URL - https://[Hotspot IP Addr]:50000/remote

                Login

Note:

If the Raspberry Pi's Ethernet cable is plugged into a LAN with Internet access you can access your ham radio remote from the Internet, local LAN and WiFi through the RPi Hotspot.

If the Raspberry Pi's Ethernet cable is not plugged into a LAN, you will only have local WiFi access to your ham radio remote through the RPi Hotspot.

Dont forget to change the WiFi network Password

Option - 7 = Change the Hotspots SSID and Password

That is it you can now access your amateur ham radio station through RPi Hotspot whether you have Internet access, a Router or a Local Area Network.

Trouble Shooting

If you don't see the RPiHotspot make sure that rfKill has not blocked WiFi.

You will see this when you login:

Wi-Fi is currently blocked by rfkill.

Use raspi-config to set the country before use.

Notes

No Internet resolve Domain name in hosts file:

                1. sudo nano /etc/hosts

                copy/past

                Ctrl-x-y-Enter

Conclusion

It is totally possible to access your amateur ham radio station remotely through RPi Hotspot whether you have Internet access a Router or a Local Area Network.
