Hi Paul, VLF,
Excellent, very well! Just a few errors. The QRN has been very low.
What was the phase pattern?
We seem to have some margin down to the limit, so there could be more
QRN in the coming days.
It will be very interesting to see how many days can be added to rise
the SNR. There will be a limit somewhere i guess. So it is good to try
that out before we start with undecodable messages (undecodable in a
single attempt).
The periodic actions remain active. Tomorrow, same procedure as every day.
BTW, after completing the large 2970 Hz coil (including the variometer
and drive motor) (waiting for dry wx to test it) i started to build
another one for 8270 Hz and 700 mA antenna current. So then i can
radiate about 400 uW there.
73, Stefan

An easy copy: 'TEST' Eb/N0 = +3.9 dB, BER 31.25%
Carrier S/N: 16.0 dB in 35.9 uHz
: -62 dB in 2.5 kHz after blanking
