Are there any satellites on 2.4 gig so I can check out my old AO-40 dish.

AO-51 spends a significant amount of time with a mode-S downlink. Very loud. Nothing through May 3rd, but check the schedule periodically for updates.

Hi Nels, W0TUP
You don't mention the size of your dish and the overall System Temperature of your receiving system for 2.4 GHz but if it was good for AO40 you should be actually able to receive a small level of Sun-Noise.
As an example:
Using my 1.2 meters dish with an overall System Temperature of the system of about 72 kelvin I was in condition to day to get about 3.4 dB of Sun-Noise as the included diagram showes.
The signal radiated by AO-51 is too strong to evaluate if your 2.4 GHz receiving system is in good shape or not.

As a reference point, I was able to see half an S-unit (approx.) of sun noise with my 85cm offset feed dish with helix feed and MKU-232A2 LNA. Pointing at trees (forest) on the horizon also produced about the same noise increase as compared to cold-sky. When I get my AO-40 stuff back up I will make a more precise measurement using my SDR-IQ as detector (0.1 dB resolution in gain). Also the SDR-IQ can switch off AGC.
