Been testing the DX Patrol Ground station for a few day's now and had the same problems with poor GPS reception.
Today the GPS suddenly stopped working. Seems that the GPS antenna is defective now.
When i connect the GPS antenna from my Leo Bodnar GPSDO the reception is a lot better than with the supplied antenna.
The fix is much faster and i receive up to 10 satellites. ( antenna inside near the window )
I run the ground station only as uplink in portable operations because it has VSWR readings on 13cm.
SDR Console/Bullseye LNB is used to check the downlink.
