When I wanted to calculate the distance between our QTH's Google maps was on a go slow, so I did a quick and dirty calculation from our QTH Loc's.
My location is top left of my square, I noted that your are top right of your square. I have drawn a measure on the map and the corrected figure is 49.615 km.

Even better results, I look forward to the next time.

LF,

Following my 9.090 909 kHz transmissions last Saturday I received positive reports from the following stations:

Many thanks to these stations and to the others who tried to copy me but reported no success.

STATION SET UP

Home built VLF TX with a Droitwich-locked frequency reference and a programmable divider (10.000 MHz / 1100).
Output power - approx 100 watts RF from a MOSFET PA and 30 volt supply.
Aerial - 40 m end fed inverted 'L' at a height of 10m. - running NE / SW
Loading Coil - home made 1.3 H on a wooden-framed former.

Paul Nicholson believes that with a long and stable transmission I may possibly be picked up by mainland European stations.
I hope to be transmitting on VLF most weekends and will publish times and frequencies as appropriate.
