How to send GNSS/GPS to nmea 0183 usb stick

[Sea-and-Sea]

Hey guys, my current setup:
Raspberry pi4
Moitessier hat 2
Openplotter lates version
Opencpn 5.2.4
FTDI USB nmea 0183 TX/RX stick

I'm trying to output GPS/GNSS from the Moitessier hat to nmea 0183 using the USB stick to my VHF radio that has nmea0183 input

in Openplotter Serial setup:
device ttyUSB0
alias ttyOP_nmea
data nmea 0183
connection SignalK
id nmea
baud 38400

in Opencpn connections setup:
type Network
Direction Output
Protocol UDP
Network address 0.0.0.0
Network Port 10119
Priority 1

type Network
Direction Input
Protocol Signal K
Network address local host
Network port 3000

Signal K config

ID opencpnOUT
data type nmea0183
NMEA0183 Source UDP
Port 10119
Sentence Event nmea0183out

ID nmea
data type nmea0183
NMEA0183 Source Serial
Serial port /dev/ttyOP_nmea
Baud rate 4800
Output Events nmea0183out
Sentence Event  nmea0183out


the VHF radio says "no gps signal"

When i run 'cat /dev/ttyOP_nmea' i get no output reported (same on cat /dev/ttyUSB0

I think i've followed instructions in OpenPlotter, OpenCPN and Moitessier  and can't see what i'm doing wrong. 

Any help greatly appreciated

Thanks
Colin
