Dear Stefan,

Many thanks for your continued support, enco= uragement and advice.
I shall start by using QRSS-3 and later switch to= a very long carrier timing.

I plan to increase power over the Chri= stmas holidays but any= report would be
most welcome and help to keep up morale.

=20 Chris, VLF,

Despite all my optimism i do not assume to receive your signal here in JN49IK00WD. But Jim/M0BMU or Roger/G3XBM is not even 50 km distant to your QTH. If you can transmit a longer carrier, some hours long, maybe someone near your QTH will receive your signal.
I have generated a usr file which people may use in SpecLab for your transmission. It is set to 424 uHz and 10minutes per pixel, 8972 Hz and locked to GBZ. It includes band limiting and a noise blanker and clipper.

Maybe this helps for the first UK-UK contact! :-)

I have set my newly modified split screen 9kHz grabber at :-


to monitor your frequency, the other half of the split is currently on Rogers G3XBM favourite frequency.

LF,

I have had permission from the Met Office to do some more VLF test transmissions.

Time:    0900 - 1200 Z      Monday 13th Dece= mber 2010   
QRG:    8.972 kHz
Power:  50 watts RF (max)
Mode:   QRSS - 3   to  QRSS - 30
Aerial:   40m inverted 'L' - height 10m

I have a resonant aerial system and 0.14A of aerial current so hope to get some local reports.
