HP Elitedesk as proxmox server
5th January 2024

So I have been reading a lot about a linux virtual machine system known as proxmox.
I had tried installing it a couple yoears back but never did much with it as the PC i put it on had issues.

Looking around Ebay a few months ago I discovered the HP elitedesk line of mini PC's
They were originally intended to be office workstations a bit beefier than a thin client.
I found the elite desk 800 for sale with a 8 gigs or ram and no hd for about $60.
I bought one. added another 16gb memory to it that i had on hand and a 2 terabite ssd to it for another $60. I installed proxmox and started adding virtual machines to it.

First I created a debian server vm to be an apache webserver and run gridtracker a ham radio program. That is the server hosting this blog.

Second I decided to try creating a container. A container is like a limited virtual machine. I picked a container with the Gallery photo server software that installed with out problems. I have some family pictures on it so my extended family can access it.
I also have a Jellyfin server for hosting a few videos on the local network.
I also created a windows 10 vm just to see if I could and that works fine too.

Conclusion. The cheap little HP elitedesk works quite fine for running multiple home servers via proxmox. Didnt cost much more than a raspberry pi but offers a lot more muscle.
Give it a try

440 digital net
20th January 2024

Recently on our Saturday net I brought up the idea of having a persistant digital net
on our 440 repeater. Here is a breakdown of what is needed to participate
What do you need:
A 70cm (440) radio set totalk on our repeater frequency of 442.750MHz with a + offset and 156.7 tone
You will use the free fldigi software set to mode MFSK 64
You will need some sort of interface for radio to PC. This could be one of the following.
A signal link, Digipi, or even a cheap USB sound dongle. If your radio has a usb port then you have everything you need interface wise.
Also you may want to use some other software for auto replies which will be covered later.
