NOAA 15 & 18: APT Composite Construction with WXtoImg 2020-07-01 20:45 EDT (FN20gf)

This video is a raw screen recording of the process of constructing a composite image from the NOAA 15 and NOAA 18 satellites using WXtoImg. In each recording you can see the satellites switch between day and night mode as they cross the solar terminator. I have left this at original speed so as to leave the audio intact. This means that the viewer should be able to create the images from the video audio if desired. The antenna used is my cross yagi for 137MHz, and the radio used is an AirspyR2. No additional LNA was required.

The first pass is mid to low (22 deg) and to the west, which gets good reception when line of sight is available, and the noise comes from some evergreen trees and a house blocking my LOS to the NW and S. The second pass is reasonably higher (38 deg) and only really experiences one line of noise in the middle when i had to move my station and antenna to get around my house, but the pass was only at 38 deg, so i couldn't maintain LOS. Trees to the South cause the usual problems with signal reception below 10 deg S, and hills obstruct most things below 6 deg to the North.

NOAA 15 Pass (22 deg): (0:00)
NOAA 18 Pass (38 deg): (11:16)
Processing & Composite Generation: (24:32)

Why is signal playing 2 times with small delay?
