Hi Dimitris,

My congrats! That is a good success and progress!

Can you tell more details?
How much power was used?
How much antenna current?
Was it the 3 turn loop?
What type of receiver was used on the RX site?
Is that site in a quiet location?
Which bandwidth or mode?
Was it actually QRSS-10 (Which i would watch in 122 mHz)?
What was the SNR?
Is there a screenshot for us to see?
What is your plan for today? :-)
Who is the next distant station?

This could be the beginning of a growing worldwide VLF activity, if you can 'mobilise' a team of stations who build up RX and TX systems arround VK.

73, Stefan

Hi Stefan and VLF,

well, I am now officially hooked! My signal on 29.5 kHz (VLF's edge)
has been detected 22.3 km away in Canberra by Dale VK1DSH. Only
casualty is the russian mica capacitors (K31-11-3) which got really
hot (I was focusing on the amplifier and neglected the poor caps). I
had 4 of them in parallel, each 4700 pF.  Maybe they will recover if I
let them cool down :-)

That's probably a first for Australia, I haven't heard anyone else
doing tests like this.
