I know this issue has been dealt with in some depth in:
https://opencpn.org/wiki/dokuwiki/doku.p...sa_clipper
It seemed that a lot of interfacing electronics was required.
However, I just tried connecting the NASA Repeater to a NMEA to USB interface in the Pi running Openplotter. I filtered out all the NMEA other than the three Sentences that it requires and up popped Lat and Long on the display. When I selected a waypoint to go-to in opencpn I could see that the RMB sentences were being outputted and the repeater started to display Bearing and distance to waypoint etc.
All is well so far! Just one small glitch. after a few seconds the display flashes "No RMB" for about half a second and then back to displaying the correct data for about a second. The flashing between the correct data and no RMB continues and never stops.
If I switch to the position display, Lat and Long are steady - just the normal changes in the last digit as the GPS position moves minutely.
The NMEA debug window shows the RMB sentence being output to the port every second or so with no errors.
Any suggestions as to the cause of this issue?
