1 Scope
This project is a follow-up of a number of predecessor projects. From time to time, projets need a face lift, and my SVXLINK noe suffered a nearby lightning strike, and lights went out. Time to replace the machine used up to now.
The most recent computer hardware used for the project was a Seagate FreeAgent, an early embedded platform that you could use as a hacker. Even though we're using Raspberry Pi 3B+ today, version 1 still is very useful and so I decided to assign one of my surplus boards to this task.
Previous experiments in this context:
- Porting SVXLink to OpenWRT
- A SVXLink Server based on the BeagleBoard
- Setting up a remote, electrically independent, low power EchoLink relay
- The Echolink Node DB0BUL
- Bedienung des DB0BUL-Echolink-Knotens über Funk
2 Mechanical changes
- The entire hardware was upgraded to be a 19" 3HE board carrier. I am using two VERA BICC Monovolt, giving me sufficient power at 12 and 15 volts.
- The mast unit has been replaced with a most recent Miktorik W60G "wireless wire" operating at 60 GHz.
- The main switch unit has been replaced to be a 1HE Mikrotik RB2011RM with 10 ports. The former switch unit, a noname 5 port switch went out of operation.
- The Raspberry Pi 1 now operates a USB hub, which again connects to an external disk of 500GB, acting as home partition.
3 Other Hardware
I am using the FUNKAMATEUR transceiver interface, however only the PCB, without the original case:

4 Software
In order to retain a working Debian / Ubuntu distribution that includes and monitors also the SVXLINK files, I decided to use a trick. There are many tutorials out there how to compile SVXLINK yourself. But the idea of having unmanaged files on my disk sucks.
- This works fine: https://github.com/sm0svx/svxlink/wiki/InstallBinRaspbian
So this is my sound card device architecture:
