Sounds from the Amsat QO-100 Es'hail2 stationary satellite

-

 

 

Over the last 1-2 years several radio enthousiasts have mentioned the Amsat QO-100 Es'hail2 stationary satellite but so far I had no clue where to begin receiving signals from it. There seems to be no shop selling a complete kit so one has to source and assemble the parts.

Tije de Jong helped by building me a custom stand for the satellite dish, Hans Holsink (https://www.youtube.com/watch?v=ZDBIMjCUKtY  / www.hybridpretender.nl) gave me some tips over the mail as did William Lagerberg, a fellow radio enthusiast who has built a small forest of antennas around his home.

In preparation I looked for pages and videos of other setups but often what I found was way too technical for me, or focused on one or two aspects while skipping over everything else.

So I gathered material from different sources, gleaned information from several websites and videos.

But above all I had the help of Tije, Hans and William who enabled me to get there.

One shortcut that I thought I was taking in the beginning was using an app to get the dish lined up but as it turned out the app seemed to think the satellite was playing hide and seek, sometimes in plain sight across the street and then slowly disappearing around the corner ;-) Also, I used LiDAR measurement in the app to establish what size and type dish I had bought (a cheap no brand thing in a store where immigrants buy satellite dishes to watch homeland tv) but later on Tije pointed out to me that the dish on the app screen looked nothing like mine ;-) which explained why the orientation tool of the app had me pointing the dish ever higher.

Once I used the information on https://eshail.batc.org.uk/point/ I got going and lining up the dish was easy.

Finished Pavoni & Fuji PXG4 pid: Probe Inside the Ring

Delicious cup: all the work was well invested! At the end of the previous blog about the pressostat and PID working together , I mentioned that I would like to clean up the xmas tree of wires and have as few cables and probes as possible to visually disturb the classic design of the La Pavoni. Getting rid of the probe that was fastened with copper tape to the top of the brew group was a priority. I wanted to hide a new probe in the cooling fin as close as possible to the brew group. This morning I asked Tije if he could do that. He would need to drill a straight hole of 3mm diameter in the 4mm inner ring of the cooling fin that sits as a tight clamp around the brew group. Always the optimist, Tije set to work: First, Tije made a piece of aluminum to fit the inside of the ring. Drilling a thin hole straight through the curved aluminum, if possible tangentially going through the inside of the ring to touch the brew head directly, you need the support of the temporary insid

Tiny Cheap Fluid Bed Roaster by Tije and Jan

(also see Daily Coffee News feature ) Tije designed and made the following structure for a tiny and cheap fluid bed roaster, to which Jan van der Weel added the Arduino parts, electronics and programming: Sketch by Tije de Jong Jan sourced a very cheap blower (€ 11) to start with, Tije developed and constructed the mechanics, Jan built together and programmed the TC4 / SSR electronics.  On his blog, Jan will specify exactly how the TC4 part is combined and programmed and I will copy these details into this blog entry, just as Jan will use this video in his blog. We did a few test roasts to make sure it works at all and it does. Towards the end, the first roast tended to get a flat BT line and airflow was slightly decreased. 200g seems max load of green beans. Second roast a little more power was given to the heater. Next we will try the Background Roast driven by the PID software of Artisan. A week later, with updated software that works better to change the fan

KiwiSDR2 [radio]

  Despite selling one and giving away two of the five monster vintage 'boat anchor' receivers that I had, I still enjoy listening to shartwave radio. The modern iCOM R8600 that I also have has a wider range plus some decoding options but it's not easy to figure out what encoding is used on which frequencies. The SDR-Control app from Marcus Roskosch at https://ham-radio-apps.com/ makes this much easier and also allows some remote control of the receiver so you can place it and an antenna at the top floor of your house while listening downstairs. I also got the SDRplay RSP1B box: This offers a great listening experience at a very low price compared to the iCOM hardware. I had one before and bought one again after a (somewhat limited) Mac version of the software became available. This device needs a computer to be connected to the receiver. For some time now a nifty little device has appeared which not only works standalone, it even allows you or anyone else to utilize the
