Oops, I should point out that the "CW" that is heard isn't actually CW.... it's code, but unsure of how it's modulated (looks like maybe FM with some data hidden with it?)

Check out the audio of this Satnogs observation: https://network.satnogs.org/observations/320591/ There is CW, followed by some digital. I don't know CW, so can't confirm that it's actually Irvine-1. But if somebody can confirm, then it's likely that what follows the CW is also from the same sat. --Roy K3RLD
