Having listened to a recording of the pass mentioned below, the chirpy signal is crystal locked, but the doppler shift deviated significantly from the auto-tuning, which suggests the keps in use need some refinement. Unfortunately the two signals are only 300 Hz apart.

From the chirpy signal I was able to decode from the start of a sequence

00C01.A..29000000000000000.502C5... Apologies about jumping to the conclusion about the crystal. Colin VK5HI

Observations from the pass 1242 UTC to 1255 UTC, over VK. Copied two CW signals on nominal 437.275. One was very unstable and chirpy with slow CW, the other was clean, fast CW, but quite weak in signal strength. The unstable signal drifted down the band very quickly, definitely not crystal locked. Also copied SEEDS on nominal 437.485, but may be slightly lower in frequency. Signal clean but very weak. Visible on Spectran but not decode-able. This pass was in Eclipse. Used auto-tracking throughout the pass, which may have been a retrograde move. Colin VK5HI.
