MF,
Here i've made a diagram showing the SNRs as a function of time of those
stations who received me on 477 kHz since this day.
It shows clearly that the groundwave path must be very stable over the
daytime and seems to be limited to less than 500km. There are stations
who are continually monitoring the QRG but as soon as the sunrise comes,
no signals are detected in the UK while the levels are 25 dB above the
decode limit in the night.
So far there were no TA decodes during the last night. I think i will
run the TX for another 24 hours in that mode. I'm looking forward to the
effect of different RX locations when the sun goes down in some hours.
The diagram is here: https://dl.dropbox.com/u/19882028/MF/OP4SNR.png
73 and tnx to the RX stations!

MF,
Thanks to PA3ABK for the QSO!
Maybe i'll be back in CW tomorrow. At least i will run OP4 on 477 kHz
over the night, now that the system is resonated to MF and the TX is
ready to go...

I will listen....will u have enuff little watts to make it across
the pond..
Yes, i think so. But i don't know when the band opens to your
location. Maybe you will hear me. If so, pse give me a feedback.
