GB3BSS 13cm beacon recording 11th Sept

GB3BSS in IO81SR is 248km from here. It has been audible most of the day, with a few aircraft scatter peaks.  This morning it was a solid 549 but now it is fading and it only about 12dB above noise in 11.7Hz SDR bins.  Recording is with 100Hz CW filter and two notches alongside to reduce ringing.  The rapid fading is fast and deep enough to remove whole characters from the CW.

Screengrab shows the FSK CWID with characteristic keying sideband fuzz, and a bit of weak aircraft scatter at 22:09:10
