Hi both thanks for confirming the results from my DCF39 monitoring (via CT1DRP) over the years. I think it maybe the old story....yes its more uncomfortable to use ears in summer, but the data modes
Hi Mike well at 137 the daytime signal is skywave over about 700km I watched Budapest (about 1200km) and there is a distinct "dome" in the response at local noon at mid path. This is higher in summer

Hi Markus I did not spend a lot of time on day-time analysis but over one year (DCF39 to Porto) I did see anout 5dB better noon signal in summer than winter. I also found some connection with electro
Yes Alan, I also think the "dome", due to strongest D-layer ionisation around local noon, is the essence of good daytime skywave LF and VLF propagation. Loran-C observations seem to show that though
