Launch Site:
• 446.050 MHz Simplex
(Note that some radios assume these are repeater frequencies and attempt to put a 5 MHz offset in the transmit frequency automatically)
Track & Recovery Operations:
Repeaters:
• 448.450 MHz (-5 MHz Offset, 100.0 Hz Tone) PPFMA repeater.
Simplex Frequencies:
• 446.100 MHz EOSS 301 Field Simplex
