B&G V60B VHF/AIS broadcasting incorrect 0.7kn SOG while stationary?

Hi all,

I recently installed a B&G V60B VHF/AIS transponder with a dedicated GPS antenna and while stationary it is always broadcasting 0.7knots SOG for AIS.

I opened a case with B&G, sent in the radio, and they determined it to be defective and sent me a brand new one. The second one also exhibits this behavior. Furthermore another boat in my marina was reporting 0.7knots and I asked them if they had a v60B and sure enough they do!

The GPS signal is stable, I've tried both the internal antenna and the external antenna. Additionally the NMEA2000 data coming from the device reports correct SOG as viewed in the MFD. The SOG displayed on the unit is also constantly 00kn.

Anyone else experienced this issue and ended up with a resolution? Probably going to go back for another warranty replacement, but don't want to be installing the radio over and over again every 2-3 weeks!

Thanks,
Eric
