• eoss097_k0ani-11_n0ti.txt - recorded by Bob Schellhorn, N0TI at his QTH. Thankfully we have this log which shows K0ANI-11 seems to be back in good health. However, it appears Kenwood radios are having a hard time decoding packets from this bird while KPC3s sail along noticing nothing particularly strange about the packets. This oddity is under currently under investigation.
