| Receiving 10 GHz EME with a small dish and LNB https://youtu.be/Beurcep8Tj0 You can receive 10 GHz EME with a simple setup. I used a 76cm satellite TV dish with LNB, RTL-SDR stick and software. In this video I discuss the dish setup, using a stock LNB, modifications for better frequency stability, automatic tracking of doppler shift with WSJT-X and HDSDR, and early results with this system. I should have mentioned aiming a dish of this size on 10 GHz is critical. The 3 dB beam width is about 2.6 degrees. In practice I find that if I aim it slightly "ahead" of the moon in its trajectory across the sky I get consistent signal for about 5 minutes, then it starts to drop off. I move the dish every 5 minutes. In the video I mention KA1GT's notes on modifying and using the Avenger LNB. Here is a link to that: https://bobatkins.com/radio/10Ghz_EME...
