Betreff: VLF: Night-transmission on 8270.1 Hz

Hi VLF,

Si= nce 18:14 UTC i am transmitting on the ground loop antenna again, this
time on 8270.1 Hz, where RN3AUS is watching from= near Moscow! After the
recent very strong s= ignal at SQ5BPF in 976 km distance i like to know if
the signal can make the 2040 km path to Alex as well? It is in the= same
direction that SQ5BPF but more than tw= ice the distance. Will this work?
Because th= e antenna is beaming towards Paul and has its null into the
direction to SQ5BPF and RN3AUS. Anyway the strong signal in= Poland...

Now= i'm sitting in my car here, the sky is clear, the moon is full and
it is below 0 C here. I have some tea which is stil= l warm, more or less.
The DC measurement at = the loop tells it has just 57.5 Ohm at f=3D0! That
is the lowest value i measured so far.
The accu display tells me: 12.8V, 40.9A, 524 W, 85% rest capacity and about 2.5 hours rest time left at this power l= evel. I can measure the
antenna current with= a Rohde&Schwarz scope using the spectrum analyzer
function. It tells me -6.3 dBV of the fundamental frequency, mea= sured
across a 0.2 Ohm shunt resistor, so th= at is equal to 2.42 A antenna current.

Unfortunately the frequency is not covered by Paul= 's excellent grabber.
Maybe he can give some= informations about the signal strength? It should
be my strongest signal since the kite experiments in 2011.

The carrier will stay= on the air for 2 hours.

Al reports are welcome.
