The filter governs what the APRS-IS network will send to you via the
Internet. Every packet that is received on an RF port is gated to the
APRS-IS if you've kept the default settings in APRSISCE/32, provided of
course that you have a valid passcode for your callsign.
Only Bob can answer what PSAT inserts into a digipeated packet, but yes,
I believe it responds to ARISS as a digipeat-able alias.
