Re: New version of kerberosSDR app

Had time this weekend to fire up kerberos. Decided to use dipole antennas as monopole by removing ground side of dipole and just tilting the remaining antenna to be vertical. Great results!

Problem with direction

Is anyone else having problems with GPS heading? As far as I understand red line is supposed to be the gps heading, but for me it usually points 20-25 degrees to the right from where I'm actually heading. The regular blue arrow points correct.

Thank you :)
