I’m fascinated by the FM low orbit satellites that can be worked by amateurs on FM frequencies. Recently, I was able to catch a pass and the QSOs going on between different operators.

One of the interesting things about seeing it on a waterfall is that you can see the doppler shift as the satellites travels through orbit. From my location I could hear operators in DM14 and EM69. Additionally, it starts with some Spanish speaking operators, which I presume are in Mexico. See the pass below.
