Yes, a strong signal here and perfect decode of the 3 chars:

            H-field           E-field             E+H field
 7th/8th  10.5 dB 99.8 deg   9.0 dB 107.3 deg   12.5 dB 103.3 deg
 8th/9th  14.1 dB 88.3 deg  12.5 dB  93.8 deg   17.3 dB  90.9 deg

Signal phase repeated fine both nights.  Given the S/N of your 2 char
success, you would be very lucky to do 3 chars in one night, but two
nights ought to do it.
