Currently running on a RaspberryPi 3 for no good reason. I was going to put it on the air with a TNCPi but ran into problems with AX25 connects. Any attempt to connect to the system caused the kernel to panic in a spin lock. The AX25 code isn't really actively maintained so any asks for help went unanswered.
Be that is it may, you can telnet to dx.ka2pbt.com port 7300 for the CLI client or you can point your browser to http://dx.ka2pbt.com:8080/spots.php for the last 25 spots from CQ Zone 5 not in CQ Zone 5.
