Content preview: 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=20 run the TX for another 24 hours in that mode. I'm looking forward to the=20 effect of different RX locations when the sun goes down in some hours.
