GPS setup inconsistent #gpsd #ft-817

Hi,
I try to make my own image. I added the following to my /boot/config.txt
# Configure gpsd
START_DAEMON="true"
DEVICES="/dev/ttySC0 /dev/pps0"
GPSD_OPTIONS="-n"

Then I rebooted and I got my GPS working. Then I moved my setup to different room and since then the GPS is not working.
pi@w4mhi-shack:~ $ systemctl status gpsd.service

The /dev/ttySC0 disappeared. Any idea what's going on?

Thank you & 73,
Mihai (W4MHI)
