The MODE field refers to the transmission mode - FM, SSB, etc.  The
fields related to a satellite QSO are PROP_MODE (this is always set

I'm pretty sure Rick e-mailed you the PDF written by N5JB that shows
the 7 fields that must be present for a valid satellite QSO in LOTW,
including the two I mentioned above.  Others can be added, but are
optional.  The document is found at:


Hope to see some of our QSOs match up as QSLs in LOTW soon.
