Скачать или смотреть Slow Scan TV (SSTV) audio from a low power 500mW French balloon on 144.650MHz (callsign F4KMH)

If you are interested in receiving Slow Scan TV (SSTV), it may be worth keeping an ear on 144.650MHz.

Fortunately I had this frequency in my scanner, and I came across this transmission purely by chance. I had not heard anything about it.

This frequency can be used by RAYNET in the UK, so my first thought was that they were experimenting with SSTV. However I soon realised this was not the case when I heard the announcements in French!

The speech at the start of the transmission says:
"This is the stratospheric balloon from the school of engineers at Limoges F4KMH. Frequency 144.650MHz. Beginning of the SSTV transmission in PD120 mode". At the end it says: "Thank you for your reports. 73 to everybody".

I have only been able to find this webpage:

Receiving equipment was my Icom IC-7300 connected to a colinear antenna.

The signal was a bit crackly at times but was always between 52 and 55 with slow fading occasionally.
