And another one! 📺

This pass had a higher max elevation, but the results weren't better than with the previous pass. Sometimes it even seems that shallower passes, despite the longer distance the signal has to travel through the atmosphere, work better.

With a proper cross yagi or even some circular polarized antenna as well as actual tracking this might be a completely different case of course. I don't have any of that and the great thing about @ARISS_Intl is its accessibilty! 🙂

Also check out this beautiful QSL card I found in my mailbox the other day! 😃
This was probably my first contact with the country of Angola, done on 17m using digital modes.

I still enjoy collecting paper QSL and coincidentally I just sent a bunch out after a bit of a hiatus. 📨

Enjoy some @ARISS_Intl #SSTV images fresh from space! 😊

RX: Yaesu FT-817 with rubber antenna  
Decoder: qsstv 🐧

As I went with a handheld setup again, I disregarded automatic frequency correction and just did it by ear like I used to on VHF.
Gotta look into using an Android device for CAT control, that would be awesome.

SSTV Series 32 is underway from the ISS with the theme of "World Peace" - it includes student drawn artwork on the theme.

Reminder that the ARISS-USA image library is currently offline, so hold your image decodes for future updates.

Meanwhile, why not share them here!

So having a USB dongle that does it all seemed very intriguing and it seems to indeed do a proper job. The only downside I found so far is that it's poorly documented, and even the documentation I found online was partially wrong regarding the pinout.
I have not yet tried the CI-V controls as it requires a separate cable and probably also some jumper settings (again, poor documentation). That's a project for when I am either really bored or too annoyed with setting the QRG manually. 😅

Finally got around to try out a cheap "USB2RIG" interface that I ordered off a well-known chinese retail website with my Icom IC-728 today.
I used to use a self-built interface to hook the radio up to a computer for digital modes, but that is rather bulky and also only does PTT via serial RTS and audio isolation, so a separate USB sound card is required (modern notebook soundcards don't work well). If I also want frequency and controls via CI-V the whole situation becomes even messier...

Damn, those kits from QRP Labs look really interesting. I might become weak and order their 630m transceiver, a band that I have only explored receiving so far. 160m is one of my favourite bands in winter, but why stop there?

Decoding was done with the trusty old #MMSSTV which runs perfectly fine on a modern day Linux system using WINE.
The Robot36 app for Android has delivered slightly better results in difficult conditions for me, but I couldn't quickly find a decent 3,5mm audio splitter as I like to listen to what's being decoded in parallel. 😅 TRRS adapters are a mess as well, I've spent way too much time trying different resistors to get both the level and sensing on different devices right.

Very clean reception of the current @ARISS_Intl SSTV transmissions, probably the best I've ever had with a simple handheld setup.  
The Doppler shift on UHF is more challenging than on VHF though. And while gpredict could do automatic compensation, it would mean carrying a computer with me, making the setup more bulky. So far, I am recording the audio onto my PCM recorder for later decoding, which has proven useful for several reasons.
