Re: Any way to block object or sender?

The symbol filter is not an easy one to use.  Arnold, KQ6DI, has the right approach with the unproto filter which I also suggested back on 7/30. 

-u/APBM*/APDG*/APWL*/APJI*

If you wanted to block the D overlay on the a alternate table, the syntax would be:

-s//a/D

The full description from http://www.aprs-is.net/javAPRSFilter.aspx is:

s/pri/alt/over Symbol filter pri = symbols in primary table (| => /)
alt = symbols in alternate table (| => /)
over = overlay character (case sensitive)
For example: 
s/->     This will pass all House and Car symbols (primary table)
s//#     This will pass all Digi with or without overlay
s//#/T   This will pass all Digi with overlay of capital "T"

And remember that any filter term can be prefixed with a minus (-) to block packets matching that filter.
