Yep I dont know Peter - the gps and 10Mhz drivers were running but no 1 Hz I can see externally - perhaps my friends in the military up the road in Gulkana/Tok are having fun with me - wouldn't be the first time :-)

Ive still not managed to duplicate a local 8970 +_ 0.000 source so it does so far look like "a signal" , just where it came from is the mystery but im not ruling out its Uwe at this time. Youll see how bright the Alphas are so the noise level even with the smpsu spurs is pretty low. It was, as you said a pretty stable sig

Just had the telco cable company around to cut over the voice circuits and talk noise mitigation but heavy snow causing overhead cable plant issues  elsewhere and we have a winter storm warning in effect so had to reschedule

Hello Laurence.

 

Even with Spectrum lab and the 'Frequency error correction" function active, I'm not able to generate such stable signal here.

How likely is it that a device over there did accidentally generate such a stable signal on exact 8970.000 Hz :-)

 

But I understand your frustration that you can't reproduce that tiny line  Hi Hi

Im still trying to replicate all the stuff that went on yesterday but havent been able to produce an 8970 artifact myself....yet. I just think the signal was just too dang strong :-)

I am seeing a weak line here at the moment but we have charged snow raining (reining) down - i need decrease the fft a but more too so i can delineate between 000 and 0.001Hz a bit more; I dont think the geomag/iono funnies we get at this geolat is causing much spread at this time

We are expecting some large "W" toroids in a few days and the cable company will try to reduce the noise from the Alpha XM2 cable psu's and their pseudo square wave drivers - just awful.
