QO100 DATV reception finally

Overcast today so I made time to try to align the dish a little better. One long Ethernet cable got the laptop under the dish and with SDR Console looking at the beacon I did manage to peak it a bit but I think I can do better yet. Oddly, no amount of moving the POTY in or out or skewing it made any noticeable difference. I did note however that the rain cover I made only makes a tiny bit of difference. The sky is a little overcast today so maybe signals are down because of the cloud cover. Anyway, I made a test CQ call and could hear my voice coming via the WebSDR nicely, so I made a couple of CQ calls but got no reply. I think I chased everyone away because after this there was very little activity. So, at least I know I am getting out and so a success at least in part. One thing though, the tuning is going to take some getting used to yet. The basic frequency conversion between the 10GHz band, the 2.4GHz transmit and 739MHz receive is 10GHz - 9750 = 739MHz rx frequency, and 10GHz - 8089.5…

After ages I finally made a rain cover for the POTY and led cables into the garage. Big delay there because the garage was a tip. It still is a tip, but the mess has been rearranged so I have access to the air brick where the cables come in! It's nice that when they built the house in the 1930's they put an air brick right there knowing it would be needed for a satellite dish... The rain cover is made from a sheet of plastic that came out of a smashed LCD monitor. I bent it round a bit of 110mm drain pipe using a hot air gun. it didn't quite come out as intended but it's near enough. The front is from the same piece of plastic and is epoxy glued on - yes there is a gap where the glue was less gluey, I'll fix that later. Nylon threaded bar and nuts hold it in place. And it rained an hour after I made it so it does actually work. After all the messing about everything still works. There is a nice box on order to take the gubbins - ok, the Pluto, bias tee, Leo…

I finally mounted the dish. It's been cluttering up the workshop for months now. My original plan was to mount it on a pole by the workshop which would have needed a concrete base and regular trimming of the apple tree and hedge. So, it's mounted on the garage wall with a TK bracket. Aligning it wasn't too bad except I managed first to find the Astra satellite at 19.2 degrees thinking it was the one at 28.2. After I found the second one it was not too difficult to find a satellite carrying Qatar TV using the GTMedia V8. With bolts tightened a bit and after rigging all the gubbins up I found the beacon via an SDRPlay SDR and SDRUno but the levels were well down. The Pluto and SDR Console did a far better job so there will be some setting I overlooked. I copied a couple of QSOs but working outside on a Sunday with the whole estate doing gardening made it rather hard, even with headphones! Anyway, the Pluto is the one that will be used so good to see the whole RX chain working. I have some decent WF100 cable for the LNB feed…
