Jacek/SQ5BPF asked if i will transmit again on 4470. Now he has a challenge...
unfortunately the best i can do is:

initial reference phase 59.5 amplitude 4.543e+00
carrier phase: -37.6
carrier Eb/N0: -7.8 dB
carrier S/N: -0.28 dB in 40.1 uHz

this is using the ebnaut analysis feature (thanks for posting the message), with -a1.7 -t5500 vtblank settings (0.7 version). this is 1.3dB worse than what Paul got.
so pse QRO, at least double the antenna current :)
