Hi Dave,
Got it. What we are doing at this point in the setup video is making the initial connection between our Home Server and our PC. The connection is encrypted using SSH (the command we are running to make the connection).
The first time we access our Raspberry Pi from our PC, a unique fingerprint is generated which identifies the specific hardware device our server is running on. Subsequent connections from our PC to the Pi will confirm that the same fingerprint is supplied each time we connect.
If a hacker were to get onto our network and try to emulate our server, their device would not be able to generate the correct fingerprint and our PC would refuse to connect via SSH.
Some SW updates can sometimes cause this fingerprint to change. If this happens, you can edit a file on your PC in your home directory called .ssh/known_hosts to remove the recorded fingerprint for your server and set a new one.
You can learn more about SSH and fingerprints here –

Hi Dave,
I am not sure what you are referring to here. Could you take a look at the initial setup video here –
https://homelab.anita-fred.net/raspberry-pi-home-server/#OS_and_CasaOS_Installation
and let me know the time in the video you saw this.

Brain and the WFD team met last evening, and our plans for WFD 2025 are shaping up nicely. Attached is a copy of our current plan.

I will provide a summary of two projects –
1) A portable ground station for IO-117 (A DX Satellite)
2) Recent Computing and Networking upgrades at AB1OC-AB1QB

Hi Tom,
I’m not sure that I completely understand the problem that you are trying to solve. Are you trying to use a special call sign as your to make FT8 contacts? Can just change your current callsign in the FT8 setup area where you current AB1NS callsign is set to the one for the special event? I do this all the time when I operate as N1FD. When I am done, I just change the callsign back to mine.
I hope that this helps.
Len, Anita, and I are very sorry to hear of Deena’s passing. We will keep you and your family in our prayers.

Hi Steve,
Yes, it was. It is on our Tech Night page. You’ll need to login to n1fd.org to see it.

Hi Kelly,
Folks here in New England have worked out a process using some simple techniques and equipment that you may have to help hams track down noise sources. Here’s some information for you to look at –
