Radio comms hobby: Weather satellite and ISS pictures, shortwave radio signals, space news
Since it's sent on shortwave, where the signal bandwidth is far smaller than VHF etc, the resolution is very low. It takes 20 minutes to transmit one map. I don't know why these WEFAX stations continue to operate.... For NOAA: Good to see that the overlay map is showing the correct region 🙂 NOAA-15 has a weaker signal than NOAA-19, so try to repeat with a high pass from NOAA-19. Of course, at the beginning and end of the pass, the signal will fade out but the software will still create the country overlay. You can set Satdump to delete these top/bottom regions automatically. Next, you can add a passive reflector or director to your antenna. This should be a single length of metal wire, taped to a bamboo support and positioned parallel to the dipole element, about 55cm behind or in front of that dipole element, (depending on whether it is a reflector or director - either is suitable). If a director, then its overall length should be 5% shorter than the overall dipole length, and if a reflector, it should be 5% longer. Then aim that 2-element antenna array straight up to the sky. I manually move my antenna to point it at the satellite as it passes over me, but fixing it straight up at 90 degrees will capture everything but the lowest elevation positions, where the satellite signal will be the weakest anyway. My 137 MHz is 3-elements, a driven element, a reflector and a director. (In previous photos, you can also see my 70cms antenna on the same boom - that had 7 elements and I added 4 more).
