RASPBERRY PI - GETTING STARTED

There are so many sites with information regarding this small computer that I feel there's no need for me to add  much here

There are quite a few different models out there but if you are thinking of buying one for running  some ham radio applications, you really want a raspberry pi 4 or pi 5. These will offer the best performance.

CONNECTING TO THE RASPBERRY PI HEADLESSLY

To run the raspberry pi ' headless ' and activate the wi-fi and allow  'ssh' automatically  is quite easy - first download and write the image to your sd card using something like balenaetcher to write the image, open the sd card in a pc/raspberry pi and it will open show the contents of the card

Make a blank text file called 'ssh' ( no extension ) and add it to the other files in the sd card . then make a file called 'wpa_supplicant.conf' and add the below script to that file and also place it with the other files  in the sd card

country=FR
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
network={
ssid="YOURSSID"
scan_ssid=1
psk="YOURPASSWORD"
key_mgmt=WPA-PSK
}

You need to modify the country line to reflect your country, replace 'yourssid' with your wi-fi network name and replace 'yourpassword' with your password

check this link to see how to do everything using Imager ( part of the operating system )

You will need to find your I.P address for the raspberry before you can SSH into it ( you could  of course initially set the raspberry up with a monitor/keyboard/mouse attached ) or use the below program if you have another raspberry pi networked , or go into your router which usually has a I.P address something like 192.168.1.1, it will most likely ask for a password but you should be able to find the i.p address of your new device there.

 You can install https://snapcraft.io/install/nmap/raspbian which will allow you to see your new pi i.p address and any other computers on your network

You can then install REMMINA which will make things a lot easier

<sudo apt-get install remmina>  

You could use VNC viewer which is now part of the operating system

To enable the camera  adjust the gpu memory etc  go into ' raspberry pi configuration / interfaces '

 

OPERATING SYSTEM 

 You will need the operating system for the raspberry pi, which can be downloaded using the facility  'imager'

Use a good quality SD of at least 16/32 G/byte  (use a class 10)

The speed/class  should be displayed  in a circle on the SD card

its always a good idea to do have  a backup of your raspberry pi image which you can do with the 'sd card copier' part of the raspberry pi os

using a raspberry pi as a replacement for a pc   

If you want to run  ads-b / acarsdeco2 etc you will need aTV dongle which with a modified driver will receive signals from about 10 Mhz up to 1.8 Gghz ( depending on the dongle you buy ) the driver will be installed during the setup procedure -  you will require a program called zadig if using with a windows pc

 

If you want to receive RTTY/ NAVETEX /FT8 and take the audio from  from a SSB  receiver as opposed to using a SRD dongle you will need a sound card dongle as the raspberry pi has got no audio input only a audio output  so you will need one of these very cheap sound card dongles FLDIGI.WSJX/JTDX can be installed from the 'add/remove' software facility which is part of the operating system.Seatty/TrueTTY/CW type can be downloaded from the https://www.dxsoft.com/ site
