Hi Lubos

RX is on this morning awaiting your test.

Good Luck

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  5th March. It was the first test only and I am very pleased, you saw my signal. I expected, it would be poorly visible  on 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  500 + 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):    
I will start transmission on 8970 tomorrow morning at 08:00UT. 
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! 

73!

Lubos

How strong have you been visible at OE3GHB?

Welcome in the VLF TX group ;-)

Dear Lubos, LF,
 
beneath is a posting from Paul Nicholson in the Yahoo VLF groop. His spectrum from last Saturday morning shows three amateur signals, including yours.
 
Very good!

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)

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.
