hello Bryan,

Runnimg LH on a *Pi is feasible without any problems. I have built such a setup myself, it lives in my shack and is based on a Samsung UCCM GPSDO (telco surplus obtained in China). The Pi in question is an OrangePi Zero running Armbian Linux. It runs an Xdesktop on top of a VNCserver. Obviously LH shows herself on that desktop ;-) This whole shebang allows running the GPSDO/OrangePi combo to run headless (i.e. without a display), one can use any VNCclient to check on LH via the network. Laptop, tablet, even a smartphone can be used to monitor the GPSDO. The OrangePi has both Wlan as well as wired Ethernet options.

Hope this makes sense, I did an article for Electron, the monthly of the Dutch VERON ham organisation. In Dutch, for obvious reasons. But can make it available if there is interest.

Hello to all members.

I want to add to my lab a Pi based display that would show a GNSS SV map
like the one attached to this message.

Any suggestions ?

Thank you !

Claude,

I would look into gpsd. I guess someone will have made a graphical add-on, if
not a text simulation of a graphical display. Mine was u-blox u-center with a
serial line actually from an RPi HAT, operated stand-alone.

Hi Wilko and Bryan.

I was the one who asked and I'm also interested in getting more
information, both on your project and using GPSD as suggested earlier.

Thank you,

That is OK for me !
