I was quite busy during last days, so I am writing just now.
Well... I tested my new VLF TX set of the day  5th March.= It was=20 the first test only and I am very pleased, you saw my signal. I expe= cted,=20 it would be poorly visible  on the Gerhard=C2=B4s grabber only!= In fact,=20 it was visible with S/N 10dB.
Some information:
The antenna is my MW Marconi L (24m up), but I increased top lo= ad on=20 the value 220m.
Generator is Wandel/Goltermann PS30, the finest tuning step 1Hz= =20 (OCXO).
PA is Seba Dynatronic 25W out.
My loading coil is made from 60l barrel, it contains two fixed= coils=20  500 + 500 turns of wire 0,4CuL + rotary coil made from 5litre= =20 bucket.

I am going to take some photos and give them on my websides at= the=20 weekend. I will let you know, they are there.

My next VLF test will be tomorrow (2011-03-11):    
I will start transmission on 8970 tomorrow morning at=20 08:00UT. 
Than I won=C2=B4t be at home, so TX will transmit to approximat= ely=20 12:00UT. It is the best time for VLF TX test, becouse the noise woul= d be=20 the lowest.

Thanks for your encouraging words and=20 help!

Yes, that long dash was Lubos.
OK2= BVG=20 was active that morning for a couple of hours.
