LF: Re2: VLF Reception

[DL4YHF@aol.com]

Hi Uwe and group,

DJ8WX's recent waterfall image certainly shows the French Navy's signal on
18.3. Their modulation is indeed a bit broader than GBR. For comparison, a
small spectrum plot from monday evening is attached, range 15.5 to 21 kHz.

The narrow peak left (15.625kHz) is my neighbour's TV (on the other side of a
wall, 3 meters away from the RX antenna), on 16.0kHz GBR clearly visible
(with ferrite antenna in resonance), 18.1 two peaks from Russia, 18.3kHz
French Navy (also visible on Uwe's waterfall), 20.9 possibly also from France
(MSK).

Have a good reception on 16kHz tomorrow,

73's Wolf.
