[aprssig] Local Repeater Displays on Mobiles

[Ron]

Hi Bob, I suspect many people (like me) were sending
the repeater objects from their client station. In
UI-View the REPEATER object is /m, whereas the ANTENNA
is /r so thats why so many are using /m.

So now I've moved my repeater object to the UIDIGI
node beacon text but there is a problem.
On my D7 it won't decode properly with that format.
If I put this beacon text:

;146.670- *111111z4612.74N/06320.46WrPHG8560 IRLP 2030
VE1CRA

This shows up as a fixed station with the senders
(nodes) callsign instead of the object name (146.670-)

If I put the PHGxxxx later in the string it shows up
properly (Object name etc) but the PHG doesn't decode.

;146.670- *111111z4612.74N/06320.46WrVE1CRA PHG8560
IRLP2030

Perhaps it works fine on the D700 but not on my
D7-A(G).

A second problem I see with having the object name as
the repeater frequency instead of its callsign is the
duplication problem where popular repeater frequencies
will overwrite each other.
As would happen when another repeater object somewhere
in the world also happens to be on 146.670-.

73, Ron
