3-2, I looked at the night sky for less than 10 minutes and counted 6 different LEO sats. I remember when visuals were a bit rare but at dusk it’s a common occurrence now

I’m starting a new recording project where the focus will be on “earth sound” field recordings. This includes electromagnetic fields found in dense urban environments and naturally occurring signals of the earth.
Project name: Gaia_Magnetosphere

2025 goal is improve Morse copy and sending. My fave key is the NATO. CW courses require a keyer so I have to practice with that but the real fun are the “Swedish” style keys.

The winter season is now in full swing and the evenings are perfect for listening to distant AM broadcast stations from the Midwest. One of my favorite DXing receivers is a Hammarlund SP600 along with a Collins R390A and a pair of more “modern” (1990’s era) Racal receivers.
