Go on and good luck

Thanks, for your receiving! My TX was on from 08:00 to 12:30UT. Did you detect my signal?

Hello Stefan, Markus, Gerhard and all VLF enthusiasts!
I was quite busy during last days, so I am writing just now.
Well... I tested my new VLF TX set of the day =A05th March. It was the first test only and I am very pleased, you saw my signal. I expected, it would be poorly visible =A0on the Gerhard=B4s grabber only!= In fact, it was visible with S/N 10dB.
Some information:
The antenna is my MW Marconi L (24m up), but I increased top load on the value 220m.
Generator is Wandel/Goltermann PS30, the finest tuning step 1Hz (OCXO).
PA is Seba Dynatronic 25W out.
My loading coil is made from 60l barrel, it contains two fixed coils =A0500 + 500 turns of wire 0,4CuL + rotary coil made from 5litre bucket.

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

My next VLF test will be tomorrow (2011-03-11): =A0 =A0
I will start transmission on 8970 tomorrow morning at 08:00UT.=A0
Than I won=B4t be at home, so TX will transmit to approximately 12:00UT. It is the best time for VLF TX test, becouse the noise would be the lowest.

Thanks for your encouraging words and help!=A0

73!

Wow, the next one!
Lubos, can you tell us about your station? All parameters and data please :-)
How strong have you been visible at OE3GHB?

Welcome in the VLF TX group ;-)

Thanks for the info Markus.

Yes, that long dash was Lubos.
OK2BVG was active that morning for a couple of hours.

I get this spectrum, (08:00-09:00, 278uHz bins)

http://abelian.org/v= lf/tmp/110308b.gif

which has a small peak at 8970Hz - 3.0mHz, bearing east.

To bring this out I found the best S/N at bearing 110 and
I synthesised a unidirectional cardioid by combining H and E fields.

Only 3.6 sigma unfortunately.

Hopefully Lubos will do further tests. He should be visible
here with 30uW at 1423km if the tx frequency is stable enough.
