1. ULF: Carrier on 2470.01 Hz (score: 1): Author: DK7FC <[email protected]>; Date: Tue, 01 Jan 2019 13:32:52 +0100; 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.; /rsgb_lf_group-archives/html/rsgb_lf_group/2019-01/msg00003.html (10,034 bytes)

We are operating on the 121 km band and crossed a distance of 283 km, or 2.3 wavelengths!! Certainly this has never been d; /rsgb_lf_group-archives/html/rsgb_lf_group/2019-01/msg00006.html (13,327 bytes)

Re: ULF: Carrier on 2470.01 Hz (score: 1): Author: DK7FC <[email protected]>; Date: Thu, 03 Jan 2019 19:40:52 +0100; Here is a spectrogram (attached) showing the reprocessed data of the VLF stream of DL4YHF. The 2470.01 Hz carrier leaves a clear trace, not as strong as on 2970 Hz but clearly there. The trace appea; /rsgb_lf_group-archives/html/rsgb_lf_group/2019-01/msg00028.html (14,523 bytes)

This is interesting! The attached enlarged screenshot is a comparison from DL0YHF (top) DL0AO (bottom), with same timescale. We find that DL0AO wa; /rsgb_lf_group-archives/html/rsgb_lf_group/2019-01/msg00034.html (17,263 bytes)

I would rather expect a slower dSNR/dt, like we can see at the VLF MSK transmitters. But maybe you are right. So let's hop; /rsgb_lf_group-archives/html/rsgb_lf_group/2019-01/msg00037.html (19,029 bytes)
