Interferer to 10m WSPR

David G0LRD is seeing the same interferer that I am. Looks like it is coming in from some distance perhaps by Es.

Hi Roger,
The interferer in the 10m WSPR segment came back again this evening. It's rather odd. It is a very stable carrier modulated at about 0.0875Hz (7 tones every 80 seconds). It exhibits signs of long-distance propagation (fading, no doppler). The frequency of the pulsed carrier is precisely 28.126031 Hz.

It is rather annoying - I hope it doesn't persist.
