Hi ULF,

Unfortunately the experiment must be delayed until tomorrow night, due to a heavy thunderstorm in north Italy.

Betreff: ULF: Carrier transmission announcement, tonite

Hello ULF friends,

It's time to do a ULF transmission again. Hopefully the QRN will stay low tonite. I'm planning to transmit near 1.67 kHz, which is lambda/2 for the distance between earth and ionosphere at night. With some luck we can get some gain from that resonator, like the tweaks do?

Exact start time, power, and antenna current will be mentioned later. I think the transmission will start arround 21 UTC.

Hopefully the QRN will stay reasonable low. It is certainly not the best time in the year, but anyway.

Reports welcome! :-)

73, Stefan
