Hi Chris

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:

Paul Nicholson     218 km   
G3ZJO                  46  km   
G3XBM                 45  km  
G3WCD                19  km
M0JXM                  1.5 km

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.
