DB0MU beacon on 10368.972 MHz

June 25, 2018 smithn Leave a comment

Nice conditions this evening on 10GHz. PE9GHZ, PI7ALK and DB0WML beacons all loud here in IO93NR East Yorkshire.

DB0MU just announced “Temperatur 17.9C”.  Cracking signal from JO31QX at 587km

Wind turbine scatter Doppler from GB3FNY

June 14, 2018 smithn Leave a comment

GB3FNY on 10GHz is only 20km from here, but this is an off-axis reflection from a large windfarm about 20 degrees from the direct path.  The doppler shift from the blades shows up nicely in the SDR waterfall, but just listen to the weird whooping note on the signal in the WAV below.
