From time to time we see beacons of this type:
RND000000>APRS,qAS,TheHague:/061542h6505.31S/18136.75W^054/325/A=002591 !W31! idA4000000 +099fpm +1.8rot FL029.04 0.0dB 6e +15.0kHz gps11x17
This beacons is invalid, because the longitude exceeds the valid range specified for APRS beacons [-180,180]. In the example above we see 181°36,75".

It seems strange to have this type of issue as TheHague is reported to be standard OGN version software: RTLSDR-OGN 0.2.6.RPI-GPU
@pjalocha do you think you can have this type of issue in the code of the receiver? Fixed in 0.2.7?

It does not depend on the station. Here are some invalid beacons from today.
