Two events this month, the first from the 7th to 8th and the second from the 11th to 13th (ongoing as I type). I received nothing at all on the 7th and a few poor or very poor images on the 8th.
On the 12th I received one reasonable image at 13:29 UTC and an incomplete one at 15:06. I even received a partial image at 16:36 with the ISS mid-Atlantic. That probably had the benefit that this area is clear to the horizon roughly in an arc covering Wales the lower half of Ireland.
No more passes here until tomorrow… let’s see what happens.
This is a screenshot after the fact, I was not around to witness it. The ISS had already moved out of range for me by the time I got to the PC (ok, by the time I woke up!). I was there for the next one at around 10am UTC. The signal came in strong at first but faded out very badly after a few seconds, and then faded completely out after that so it’s not much of a pic.
These are received on 437.800 and given my internal collinear struggles a bit to receive the SSTV images on 145.800 it is probably not surprising that this UHF digital test faired worse. But the blocks that make it through are nice and clear.ss
I received a few reasonable images early this morning between 5 and 6am. Hopefully later passes will yield better images. These were received on a 2m FM set with a loft mounted collinear, and decoded by qsstv on Linux.
I only managed one almost decent image from the 1st December ISS SSTV event, the others being partial or very noisy.
I am not bothering with the diplomas this time. When I checked most of them use a Google form that required me to log in (twice in one case), failed to submit and, in one case set 40 (!) cookies for the trouble.
Just managed to receive a fairly good image from the closest ISS pass. This started as it crossed the UK and continued as it passed onwards to Germany. There were a few dropouts (I run the FTM100DE with an open squelch for these) but all in all this pic is better than any that I managed from the last series. The transceiver is connected to a white stick 2m/70cm colinear in the loft and I really need to stop being lazy and set the Arrow up for these passes.
Not done very well at all with the current ISS SSTV event that runs from the 21st June, or with the previous event a few weeks before. So far, I have not one single decent image to show for it. Not sure why exactly, nothing has changed here. All I can think is the station transmits earlier, completing as it approaches the west coast of Ireland and so it does not start the next one until it is south-east from me. But I can’t remember how it went last time so not sure if that is even a thing. Anyway, I submitted the ‘best of the worst’ image, which at least has a complete top and tail, but only a fuzz for the actual image of whatever it should have been.
I could crack out the Arrow and go dancing in the garden. Maybe next time…
I finally got myself a handheld satellite antenna – an Arrow II. It packs away quite small and is easy to put together, albeit you need to remember the size of the 2m elements when waving it about if constructing indoors like I did first time. I got the one without the diplexer because I plan to use two handhelds for full duplex rather than acquire a full duplex radio.
Of course, the first order of the day was to try to bounce APRS off the ISS, in which I failed while waving said antenna about the shack. I received APRS easily enough but it was just too hard to try to track the ISS from the shack. I missed the good pass because the FT2D was refusing to see the GPS and I had not stored local coordinates – I have now.
So, day 2 and I assembled just the 2m elements outdoors. Turned the FT2D on and it found the GPS almost immediately. I wonder just how much lead paint is on the shack walls! After figuring out where the ISS was on what was quite a low pass for us I picked it up and, finally got a call in. The following are screenshots from ariss.net:
The actual ‘raw’ data as reported on ariss.net was “20210414100126 : M0RVB-7]USUPTS,NA1SS*,WIDE2-1,qAU,DB0NU-10:`w?pl [/`Hello from IO93_(“
Next time I will try to reply to APRS ‘calls’ but this time was just a trial run to see how many arms you actually need. I can well imagine the complexity of tracking and calling through a LEO satellite, and logging as well. Anyway, this harness, which came via Amazon and was only just over £8 may work… not properly adjusted yet but seems to fit the bill:
I managed a couple of rather poor grabs from the ISS SSTV event of the 28th and 29th January. Nothing to write home about, my setup is not suitable being simply a loft mounted colinear. However, this one fragment was interesting because when received the ISS was over the middle of Poland.
Not too bad for around 800 miles or so. In fact, I received another fragment after this…
And two further grabs on the 29th, the first over the English channel and the second as it passed over Poland.
Two good captures early this morning, again on the FTM100DE and its co-linear. These are pictures 12 (received at 04:30 UTC) and 1 (04:47 UTC) of the series:
There was another pass just now and I wanted to try the FT450D plus its 144/28 transverter and loft mounted horizontal dipole. A bit disappointing but the pass was a lot further south and the pic was received with the ISS still over the Atlantic. Anyway, this is number 9 of the series, received at 09:33 UTC:
I am rather late for this event which runs from the 24th to 31st December 2020. Due to all manner of things, Christmas included, I only managed to have a go at receiving the images on the night of the 28th. The ISS pass was in the early hours so I just left things running. Among several partial images including identifiable bits of 3 of the 12 images I found this one:
Not too bad for a co-linear mounted inside the loft with a snow covered roof. I actually saw another image arriving from the ISS while approaching Spain at around 10:25 on the 29th.
Typically, in my rush last night to set everything up I forgot to tick the ‘Auto slant’ setting in QSSTV…
