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.

Hi Wolf agn es all,
for comparison purposes I detach an image of same spectrum-width as urs
(15.5 to 21kHz).
the russian signal normally on 18.1kHz is ZAN (not on air).
will GBR be as strong as in usual mode in test mode A1A ?
regards
Uwe/dj8wx
