Hi Laurence,

 

now that we learnt how to transmit with absolute phase, couldn't we join forces? There are currently three occasionally active low-power VLF stations in Europe, and hopefully Stefan will join in soon with the small yoghurt coil. Adding four 10 uW signals coherently could increase the signal by 12 dB, i.e. result in 160 uW ERP in the main lobe of the array. We could ask Paul to first measure our phases individually for calibration, and then do some distance-difference calculations involving LWPC to focus on your receiver in Alaska.

 

Best 73,

Markus

Still looking for my first VLF  Eu signal

- some nice diffuse Whistlers come thru this evening every couple of mins...
