Hi Domenico,

The unmodulated carrier is now on, 8270.0075 Hz phase stabilised since
~1800 utc today.  I'll let you know the parameters when the next
EbNaut transmission takes place.

...and questions for Joe VO1NA:
Can you specify again the start time, frequency and all parameters of your
EBNAUT transmissions? Some long carrier has been transmitted by you and in
which hour?
Thanks in advance.
73, Domenico /IZ7SLZ

Paul, did you copy my message from last night and the night
before?
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

I am getting no decode at RC4HAA, even when stacking both nights.
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.
