Thanks Paul! That's half a dB better than I had expected, probably due to lower QRN:

+5.35 dB (average Eb/N0 of last week's 7 char decodes)
-6.02 dB (20 -> 5 seconds/symbol)
+0.71 dB (608/7 -> 512/5 symbols per character)
+1.16 dB (0.35 -> 0.4 A antenna current)

=1.2  dB expected Eb/N0.

Best wishes,
Markus

An easy decode: 'DF6NM' with Eb/N0 = 1.7 dB and constant ref phase.

S/N: 16.25 dB in 390.6 uHz, -51.8 dB in 2.5kHz
