Same power as last time at XNS - 200 watts rf. Not sure what John was running but I'm sure he'll let us know. Interesting on the big time difference in minima. We're running significantly different antennas ... John's is a large transmitting loop (about 500' perimeter) and mine a top loaded vertical (about 90' tall).

 

No plans currently for a uHz grabber.

Hi Jay and John, brilliant! Indeed the kind of surprise I like! Amazing how those slow signals seem to virtually tunnel underneath the noise. 

 

Again there were long steady runs, interrupted by one fading (or spreading) period. Interestingly the minima on the two signals appeared at quite different times, around 1:40 for XNS and 3:15 for XES. The fieldstrength of both was similar, and about 6 dB down versus Jay's last time - did you run the same power?

 

Are there any plans for setting up sub-millihertz receivers over there?

 

Thanks again, and best 73

Thought we would leave a little surprise for you this morning! Poor receiving condx this side of pond due to heavy QRN so decided to 'probe' the uHz detectors.

 

137780.310 = WD2XNS

137780.280 = WD2XES

This morning I found what looks like a dual-frequency signal in the narrowband slot:

Frequencies accurately 137780.310 and 780.280 Hz, about 0:30 to 4:40 UT,  30 nV/m, westerly incidence.

 

Any claims? Jay?

 

Best 73,
