Again a very good signal at DL0AO, about 12 dB in 1.5 * 424 uHz:

We're also running a 47 uHz instance in the background, still showing yesterday's experiment:

What a splendid start into the New Year!

Best wishes to all,

Betreff: ULF: Carrier on 2470.01 Hz

Hi ULF,

Due to the recent success on 2970 Hz i am now TXing again on my ground
loop antenna. This time, since 12:08 UTC i am transmitting on 2470.01
Hz. Again the TX power is 520 W and i'm getting 2.75 A antenna current.
This time i need 1.72 uF for series resonating the antenna. As usual, i
intend to run the carrier for 2 hours.
Reports are very much apprechiated :-)
Unfortunately my own tree is shut down but i'm recording the stream of
DL4YHF and IK1QFK again. Also the DL0AO crew is watching and recording.
Maybe even Paul will get something significant?

With some luck, 2.47 kHz may propagate even better than 2.97 kHz ??
Optimism is the key word for the year!

Oh and attached is a spectrogram produced from the stream of DL4YHF,
showing my signal on 2.97 kHz. The SNR is far better than i ever
expected from such an antenna! See attachment. A long message could have
been transferred over this 313 km path!


Happy new year 2019 to all of you.
