Tried receiving SSTV images from SONATE-2 Satellite

Latest updates below.

I have tried on a few occasions to receive SSTV images from various satellites. I have had mixed results. In this attempt, the result was quite bad. I am posting the decoded image and the audio below. If someone could figure out the reason for the failure, please contact me. I would be grateful.

Grid square: MK87ki

Radio: Baofeng UV-5R

Antenna: Rubber ducky

Transmitted image

Attempt 1

Audio

Got a similar distorted image using RObot36, similar to the one below.

Using the SSTV decoder in PC, I got the following:

[sstv] Searching for calibration header... 110.6s
[sstv] Couldn't find SSTV header in the given audio file

Attempt 2

Date: 2024-09-02

Time: 0846 UTC

Recorded audio

I used this SSTV decoder and got the following:

[sstv] Searching for calibration header... Found!
...
ValueError: SSTV mode is unsupported (VIS: 18)

Then I used the Robot36 app and got the following image:

I will try with a Yagi and maybe recording through audio cable instead of playing through radio.

I got good results with UMKA-1, but here I am unable to get. What might be the reason?

Updates

T. S. Prasad VU3YFD suggested MMSSTV and RX-SSTV software. I am very thankful for his help.

MMSSTV didn’t produce good output. But, RX-SSTV gave me the images that I wanted.
