People keep asking if you can hear the Artemis II Mission with an SDR...

And the answer is "sort of!" I could just about make out the carrier (almost at the noise floor) early yesterday with a 7ft dish and wideband LNA. I saw some nice recordings of it when it was closer to Earth, but my angles were never quite right to get much during the initial orbit.

I ran a script to find out the new Elektro L5 schedules

After running a script for 24 hours below are the results:

2026-04-19 | START: 09:27 UTC -> END: 09:41 UTC

2026-04-19 | START: 12:27 UTC -> END: 12:39 UTC

2026-04-20 | START: 06:27 UTC -> END: 06:47 UTC

2026-04-21 | START: 03:27 UTC-> END: 03:38 UTC

I have left the script running, should there be any more new schedules found I will update this post

QO-100: Not accessible in the US midwest?

New to sats and still in learning phase.

Is it true that the Q0-100 is the only geostationary amateur sat and it's not usable in the usa?

Cube sat made of junk

Artemis II and project Hail Mary have my mind on space, so I decided to make a little cubesat.

The radios and solar panels available at dollar stores would make 1958 NASA engineers drool

Goes 19 Capture from August 2025

This was from a week long capture of Goes 19 back in August. I followed the guide made by usradioguy with some tweaking of my own.

Modified Wifi Grid Dish For GOES Weather Satellite

Moved the secondary reflector away from the dipole until I hit the lowest SWR possible at 1694 MHz, and covered the entire dish and secondary reflector with aluminium foil to increase its overall surface area. I'm wondering though if I missed the focal point after moving the reflector out, but that's a problem for future me. I'm still waiting for my Nooelec GOES LNA to arrive and then everything is up to go.

[Additional Info] I'm situated in New Zealand and GOES-18 & GK-2A are both at a relatively low elevation (less than 25°) so I figured adding foil should improve my gain a bit. This is my first L-Band antenna so I would love to hear any suggestions for my project. Hope this thing works. Thanks

Turning your phone into a satellite radar

THE new VR feature that lets you visualize satellites directly in the sky using your camera will be available in next update version.

In this demo: SAUDICOMSAT and CSS satellite — both captured in the same field of view, in real time.

No maps. No guesswork. Just point and see.

📱 get the app and enjoy soon the new feature: https://play.google.com/store/apps/details?id=com.filkhidadz.leotrack

SDR Harmonics

I have harmonics sometimes on the entire spectrum. I've tried with rtl sdr v3, v4, pluto sdr. With nooelec sawbird+ h1, htool ht004. With different cables, with different power supplies, but the problem isn't solved. What can I do to fix that?
