⚠️ 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
