PA6H (FGPMMOPA6H) and $PGTOP (Antenna Advisor)

[Hengist]

Q: why do some PA6H (GlobalTop FGPMMOPA6H) modules output $PGTOP,11,x (Antenna Status, Antenna Advisor) sentences and others do not?

The original standard PA6H firmware AXN2.10_5051 outputs $PGTOP,11,x sentences (antenna status/advisor messages) when PA6H is powered on.
However, some customers have been complaining about this behavior.

The current standard PA6H firmware AXN2.10_5263 does not output $PGTOP,11,x sentences (antenna status/advisor messages) when PA6H is powered on. Customer can still enable output of $PGTOP,11,x sentences (antenna status/advisor messages) when PA6H is powered on by sending command packet $PGCMD,33,x to the module.
