QO-100 Ehails2 CW beacon received using Funcube dongle, sdrsharp and existing untouched Sky digital feed

To quote M0LTE "That sounds like it’s done every single one of those 35786km"
This gives you a instant clue that this is experimenting and nothing more

I set up sdrsharp with my old funcube pro plus dongle, setting the bias-T on and using some help from some people smarter than me to know where abouts the software would find 10GHz was able to easily find the qo-100 Ehailssat2 CW lower beacon.

I left the right side coax (as you look from the back) plugged into the sky box, and used the left side into the funcube. It's not a perfect fit, but ensure the outer casing is touching the outer dongle connection.

Tune the sky box to ITV Non HD, so this is "vertical low-band channel"

The CW reads: "dl50amsat hi hi hi de qo-"

Suggested SDR settings to help improve reception

The CW lower end beacon is on 10489550.00 KHz.
You can use the web based SDR here: https://eshail.batc.org.uk/nb/ to hear all narrow band transmissions.

Martin DJ1MBB kindly send us some stickers and a nice letter to thank us for sending a carrier on UHF at the ISS as it flew over the UK. This helped them track and record data needed for their project.
