Slow-scan television

Video.

ARIS's latest SSTV event, transmitted from the International Space Station, finishes today, October 25th.

This is SSTV Series 34 and has been featuring images of ARIS hardware.

Mode is Robot 36 and frequency is 437.500 MHz, plus or minus Doppler shift.

I'm Bruce, VK3FFF from Sunny Bendigo.

SlowScan TV Series 34 aboard the International Space Station is once again all about ham radio operators capturing images.

This latest SSTV activity on the ISS is running from October 22nd through to October 25th using Robot 36 mode, which completes the transmission of a single image in 36 seconds.

The frequency is 437.500 MHz, plus or minus Doppler shift.

Various images of ARIS hardware will be transmitted and HAMs receiving them are encouraged to submit them to the ARIS Gallery and receive an event certificate.

So the, the, my last guide published, uh, just yesterday, in fact.

Any- uh, so if anyone wants to check it out, this one's brand new, is SSTV.

So this is SDR radio stuff.

So this is a Fruit Jam with the, uh, Newelec NESDR smartV5 connected to it, and this is, uh, receiving and decoding these SSTV broadcast signals.

Excuse me, transmitted signals.

You're not supposed to call it a broadcast as I understand it.

So, and it receives line by line, but this is just one of the things that sorta ham radio people are broadcasting.

Um, and the ISS does get in on it as well, uh, sometimes too.

Like can you imagine trying to build one that's got a 10-meter element on it as well to, to get up to this, but, uh, yeah, I mean, it's, it's impressive we talk about like what the, the antennas are made of.

That's proper, you know, ham radio, isn't it there? You see some of these satellites got store and forward SSDV, which I thought was a typo, and, um, especially as I play with SSTV quite a lot.

But SSDV is slow scan digital television essentially, which, or, or it's defined as a packetized digital form of SSTV, which I'm interested in.

Like, ooh, how's that gonna work? With a 10-meter uplink, you know, I, I, I'm curious about this 'cause this is a really...

It's something that I don't think that was done before, and we talk about, you know, will we get, will you be able to get through the ionosphere depending on how high the, the satellites are.

But yeah, it's a, it's a great...

Yeah, and, and there are other things as well.

We know that, you know, occasionally they send these, um, which I think they, they recently actually sent the SSTV pictures from the, from the, uh, from, from it.

It's like any new mode that I try, um, I always get Ron on there.

I got him on, you know, Feld Hell and VARA and, um, and voice and, and SSTV and all sorts.

And, you know, I, I told him that day, Wednesday, and I told him again yesterday because I reached out to him and talked to him a little bit that, um, you know, uh, he is definitely like my favorite ham radio operator.

He's my favorite person, um, from HRCC.

A lot of my stuff records to that by default, so it'll be cool to be able to play it back.

For me, in the past week or so, I've been working on SSTV receiver.

So this is with a fruit jam and a USB SDR, which is recently added capability for USB host.

This is building on top of sort of the radio guide that went live last week.

That one was AM-FM.

And now moving into some different ham bands.

And specifically, it's this SSTV broadcast where people broadcast images that you can decode.

There's a handful of different formats and a handful of different frequencies that they broadcast them on.

Uh, I also have, uh, a version of this that does, uh, like HAM radio and different, um, frequencies like that, including the, uh, A- AR, uh, ISS, uh, Amateur Radio, uh, International Space Station thing.

So they occasionally do a thing where they broadcast SSTV, uh, frames.

You can kinda capture a picture if you, uh, manage to catch it at the right time, and so I've been, uh, running out when that flies over my area to try and capture those.

Uh, and I, uh, did actually manage to pick up a staticky, uh, picture.

ARIS has announced an upcoming SSTV event transmitted from the International Space Station beginning this weekend, October 2nd, and continuing through October 6th.

This is SSTV Series 33 and will be the first SSTV event from ISS Expedition 75.

The image content is expected to highlight student education.

The mode is Robot 36 and the frequency is 437.500 MHz plus or minus Doppler shift.

Made a couple of videos here and there.

And then, um, the recent December, I think, uh, the ISS was doing a whole bunch of SSTV stuff.

And at the time I had a, a cheap Amazon Yagi antenna, three element UHF only.

Um, And I mounted a cell phone onto the boom of the Yagi and posted a video of me just downloading this picture.
