I'm taking a look at the beaconing properties in the configuration file here: https://github.com/wb2osz/direwolf/blob/master/conf/generic.conf#L420-L429. The coordinate format is one that I do not recognize. What is the format? Is the first number the degrees and the second number is the minutes and seconds combined into 1 decimal number?

How would I convert the Prime meridian (Greenwich) into this format? DMS format: 51° 28′ 40.1″ N, 0° 0′ 5.3″ W, Decimal format: 51.477806, -0.001472

Confirmed: the second number is the minutes and seconds combined into a decimal number.

The format is degrees ^ minutes and fractional minutes.
The GPS NMEA and APRS positions/objects also use degrees and minutes and fractional minutes without a separator after degrees.
This is explained in the User Guide.
