SSTV on Oscar 100

Last night I got an e-mail from David G0LRD, who has been getting some good SSTV signals back from Oscar 100, the geosynchronous satellite. I reproduce his letter and photos here. Thank you David.

"Hi Roger

Here are a few images I captured from the satellite (80cm dish, GPS-locked LNB, SDRPlay).

The two test cards were analogue SSTV, the other two were digital SSTV  (KG-STC software, Info here: http://www.g0hwc.com/kg-stv-english.html) 

Feel free to re-use if you wish.

Still on 2m FT8 RX

Overnight and this morning, I am still on 2m FT8 RX with the best DX this morning being DG2BCP (597km) on RX. So far today, 19 stations in 7 countries already spotted on 2m FT8 with the big-wheel omni antenna.

UPDATE 1800z: 47 stations spotted today on 2m with best DX DK1FG (815km).

Sunspots - Thursday February 28th 2019

Unless I am mistaken, this was a spotless month. Solar flux is 70 and the SSN still zero. A=10 and K=2.

I shall be interested to see the latest predictions for solar minimum. To me, it looks like we are just bouncing along the minimum, so it will be interesting to read what the experts think.

Return to 2m FT8

A brief CQ (2.5W to the big wheel omni) on 2m FT8 got 7 spots with best being by G7RAU (461km) in Cornwall and I have spotted 13 stations already with best DX DL6BF (479km). 2m FT8 really is amazing. Every time I try this I get spotted a long way away and I spot amazing DX. Much of this is tropo and not aircraft.

472kHz JT9 and FT8 frequencies?

Ok, so I am asking for some advice.

On 472kHz I mainly use WSPR, but wonder if there is a better mode now more widely used? If so, what dial frequency should I set?

UPDATE 1657z: In the absence of data I am currently calling CQ about 500Hz below the WSPR sub-band on 472kHz FT8. Nothing spotted yet.

UPDATE 1725z: As I have not heard about FT8 and JT9 frequencies, I have returned to 472kHz WSPR. G1GKN (99km) is a good signal, as always.

Oscar 100 amateur TV signals

Although I check the narrowband webSDR from time to time, I have not seen examples of amateur TV through the satellite. There is an HB9 site on the BATC streaming service, but I have not yet seen any pictures. By now, I would have expected to see someone posting videos or even still images. If you know where I can find some amateur TV images, please let me know.

UPDATE 1927z: Just found this https://www.youtube.com/watch?v=Yfb9_CHKDoQ

Is Trump in trouble? - NOT amateur radio

President Trump's former lawyer Mr Cohen is giving testimony to the US congress. It is quite damning.

Cambridge Proctors - NOT amateur radio

Cambridge colleges are "policed" by proctors, These men usually wear bowler hats. The  photo shows a few of these outside Trinity College earlier today.
