Frequencies for Antarctic comms:

Palmer Station:
4125 - Secondary United States Antarctic Program (USAP) Field Parties,

Have seen this reported as Antarctic comms before. 4125 Khz is an
international maritime calling and distress frequency only. They might use
it for calling as any maritime mobile station can, but it could not be
assigned to a fixed land station by any country that is signatory to IMO and
other maritime frequency agreements.

No one ever stated that it was.
