| Short Description | There are 2 signals separated by about 2 MHz, not sure if they are related. Observed on Sunday June 1, 2025 at about 21:30 hours near Taylor, TX (Austin). The reason I made this post is this signal would slowly drift up in frequency. I went back to look for the signal again after an hour and a half, but I could no locate the signal again. I am using a 100 meter loop antenna, SAW filter, and small (6x) amp. |

UPDATE: So I ran a blue shift equation comparing the change in frequency (of the main beam at 418MHz over the 2 minute duration) compared to the wavelength of green light, and I get a velocity of about 6.716 kilometers per send so this would fall into the range of a low earth satellite with a received power of about 3.162 pico-watts.
