To All from PA0SE

On April 16 2000 at 1000 UTC I received G3WSC/P at Puckeridge at S9 + 20 dB.

That means an input to the receiver of

-73dBm + 20dB = -53dBm.

Today, May 20 2000, I received M0BMU/P at 0917 UTC at

S8 = -73dBm - 6dB = -79dBm.

That means that M0BMU/P was feeding 79dBm - 53dBm = 26dB less power to the Decca aerial than G3WSC/P did.

I wonder whether Derek and Jim can confirm that.

Propagation cannot been different both days on this ground wave path as I was receiving G4GVC at -84dBm as I always do.
