⚠️ No satellite passes this session

No FM satellites pass overhead during Monday 2:00-3:30 PM this week.
This is normal — orbital mechanics don’t always align with our schedule. Check back next week!

Tip: Try Tuesday/Wednesday afternoons for more opportunities, or watch for low-elevation passes that are still worth trying.

📻 Setup Notes

  • Equipment: FT-991A with SkyRoof for CAT control and doppler tracking
  • Listen first — wait for activity before transmitting
  • Short transmissions — 3–5 seconds max
  • Call the ISS: NA1SS via W2MMD has been active ~70% of time recently
  • Phonetics: Whiskey Two Mike Mike Delta
  • Pass times in ET. Predictions ±2 min. Data from N2YO.com
