Hi Steve,

Thanks for your note. I guess I should clarify my earlier question.

Please see #1 in the AMSAT FD rules:

1.  Analog Transponders
ARRL rules apply,  except:
- Each phone, CW, and digital segment ON EACH SATELLITE 
TRANSPONDER is considered to be a separate  band.
- CW anddigital (RTTY,  PSK-31, etc.) contacts count THREE points each.
This is what I was specifically trying to address not PBBS or APRS exchanges via Digital transponders.

In past years, the satellite digital modes for Field Day were limited to two types of contacts:

1.  PBBS contacts with GO-32:  3 points for uploading a message to ALL describing your Field Day setup, and 3 points for each message to ALL that you download.  GO-32 may or may not be operational.  (AO-51 is capable of
PBBS mode, but will be operating in FM voice for Field Day.)

2.  APRS unproto 3-way exchange via NO-44 (semi-operational), ISS, and maybe HO-68.

Detailed description of the digital mode rules can be found here:
