Hi Hayden,
we had a lot of trouble with the Garmin 18x LVC.
We used different power supplies, we had a look at the protocol and so on.

Finnaly we changed the baudrate from the rs232 in the rtcm and in the gpsunit with the snsrxcfg tool from 4800bd to 9600bd.

Now it works !
Probably you can try this. 

Regards
Rainer, DF3SY

Hi,
I am having this issue with my voter board and a Garmin GPS18x LVC.

The status page indicates a GPS lock, but the board keeps throwing this warning every 2 seconds or so.

I've loaded the SNSRXCFG.cfg and checked that the unit is in NMEA mode. 
The selected sentences are left as default although I did check and GPGSV, GPRMC and GPGGA are all selected as I read in another thread on here. 

What other NMEA settings do I need? NMEA 2.3 mode on?

Regards
Hayden VK7HH
