ISS image - with antenna diversity!
I used my Arrow 3-element Yagi antenna to receive an image this morning. That Yagi is pointed directly upwards (since I have no AZ/EL rotator). It works, but obviously has poor signal reception at low elevation angles.
So I had a brainwave! I connected my 137 MHz weather satellite QFH antenna AND my Yagi antenna together using a Wilkinson signal combiner, and then applied that combined signal to the LNA and RTL v3 dongle of my system.
A few minutes ago, there was a low-elevation ISS pass at maximum 21 degrees. I received an excellent image. In the photo, the Arrow antenna is on the left side and my homebrew QFH antenna is on the right.

This is the best out of the 4 passes today, unfortunately they all occur when I’m at work and I don’t have the sdr plugged straight into the laptop and the signal is not as good as it could be.

Very poor reception on todays two passes. Mostly due to low elevation (max 11°) and the fact that i live in a valley with mountains on all sides… Which is probably 90% of Norway anyway.

Bought a new mobile antenna and will have to try to get to higher grounds during the weekend. Preferably a mountain. However most mountains with a road tend to have a lot of transmitters on top of them that will probably cause intereference.

We will see… Atleast i hope to get something that is good enough to get that SSTV Award.

Another image from an early morning pass. I see that there are a total of 12 images. I only have 3 so far (I got a duplicate today…). Still, a few more days to go, but 11th is a scheduled outage.

Only APRS on todays two passes…

Sure wish i would have known about that before driving 30 minutes in pouring rain to get clear of these mountains… :roll_eyes:

I believe its transmitting again but like yourself I received no SSTV in today.

I had 5 passes starting from 07:3x until 14:0x UTC with no SSTV.
But on 15:3x, a pass on which ISS was barely over my horizon, I could decode a fraction of one of the images.

Finally.

Slight QRM due to nearby APRS transmitter that overloaded the band.
Max 9 and 11° elevation.

Got also those two images at better elevation (for #11 a zenith pass) but not in better quality.

after a week of trying to receive the SSTV images this is what I got. I need to improve my antenna for next time.
