I have a bit of a telemetry mystery. The station is N7FMH-2 and telemetry packets are for N7FMHL-1 and N7FMHL-2. There is no record of telemetry in my APRSIS32.xml. However, It does show up on APRS.FI (copies below). That is the mystery.
N7FMH-2 is a battery box with a Raspberry Pi Zero running Direwolf Version 1.7A. It is only over RF.
Direwolf 1.7A has a feature which allows N7FMH-2 to send multiple telemetry packet by changing the “source”. It is sending from two sources, N7FMHL-1 and N7FMHL-2. There are 10 fields in use.
