More ISS SSTV

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.

More ISS SSTV captures

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:

ISS SSTV event 2020

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…

Fiddling with APRS

I’ve been fiddling recently with trying to receive satellites but without all the going outside and waving yagi antennas around… I’ve heard a few QSOs on DIWATA 2 and there is a very good pass in a day or so where I may be able to get a call in. This is using the Trio TR-9130 as receiver as it has a horizontal dipole connected, and the FTM100DE as transmitter, though so far without success on transmit.

Anyway, I remembered the FTM100 has APRS built in and the ISS often sends and receives this in 145.825 and so I’ve been leaving the radio switched on. Today I noticed it did indeed receive packets from the ISS.

I also downloaded UISS by ON6MU which seems to ‘just work’ – nice that, I downloaded it and ran it and it found the sound card and returned an APRS message on a later ISS pass. Oddly, the FTM100D did not decode that message (the squelch is set to 0). It comes with a module called SoundModem by UZ7HO which seems pretty comprehensive. Another package to play with…

ISS tonight

Nice bit of fun tonight listening to the International Space Station on 145.8 – 2nd attempt by the ARISS guys and all credit to them and their excellent team for persevering for the YOTA17 event. Heard astronaut Paolo (IZ0JPA) here on NA1SS at 57 before it moved out of reach of my 2m horizontal dipole in the loft. Also nice streaming by the BATC. I hope the YOTA members there enjoyed it and glad it worked out after the troubles on the first pass earlier in the evening. Hopefully this will mean more radio amateurs – good for the hobby.

(This reminds me that I once knew an astronaut – well ok before he became an astronaut – Piers Sellers R.I.P.)
