Receiving SSTV from the International Space Station (2025/10/04)
We have successfully received SSTV from the International Space Station (ISS).
The Space Week SSTV Event, which I wrote about in my diary entry
on September 27, 2025, has begun.
There were three SSTV broadcasts on 145.800MHz between 6:44am Philippine time and 6:53am.
I don't have a V/UHF antenna, so I received the signal using a 50MHz 5EL Yagi, but the ISS signal was strong enough to be received.
Today, October 4th, there are six chances Japan time.
It can also be received via GP, and can be received satisfactorily using
MMSSTV
by picking up the sound from the radio speaker with a computer microphone.
Of course, it would be better if you could connect it directly.
Today, there are the following opportunities in Japan time:
09:28-09:39
11:06-11:16
12:45-12:52
14:23-14:31
15:59-16:10
17:36-17:47
For detailed orbit predictions from tomorrow onwards, please install SATPC32 etc.
Actual SSTV signal being received from the ISS.
SSTV image from the ISS received during a pass starting at 6:44 AM.
SSTV image from the ISS received during a pass starting at 8:20am.
I don't have a V/UHF antenna yet. I'm using a 50MHz 5-element Yagi antenna.
Even so, the ISS signal is strong and sometimes swings up to S9.
It can also be received by GP and mobile whip.
The ISS passed overhead and then sank below the horizon, causing the SSTV signal to be cut off mid-way.
The ISS is visible for about 10 minutes, so you can receive SSTV signals about twice.
As long as you have installed MMSSTV, you can receive the signal
by simply picking up the sound from the speaker without connecting it directly
to a radio.
