Laurence,
Very interesting plots. An eyeball-average of day signal strength compared to and eyeball-average of night signal strength seems like ~ +11dB (day to night) for the 12Mm NWC path, and ~ +8dB (day to night) for the 5Mm NAA path. The latter seems good for March; and 11dB day to night for NWC to AK also seems good, although I don’t have much of a feel for the NWC-AK path. Most interesting. The (multimodal interference?) peaks/nulls in the nighttime NWC-AK path are also interesting.
Is the antenna orientation the same for each of the three cases?
Thanks,

Bob - will be listening - I need to move the passband of the loop down 200Hz so will be tweaking tonight. The Q is very high -
Thought Id share how NAA looks here over the past 24 hrs - I changed the scaling this morning to 90sec so its a little compressed on the right - this was so I can get a full 24 hours replay -
I use, for better or worse NAA on 24kHz as a beacon for you as the 5000Kms land path is the closest I can get - its a little attenuated at the moment as we still have something upthere but gives you an idea of the issues
The peak sig and s/n NAA appears to coincide with the traces we saw yesterday - Im sure my close in mountains on that bearing arent helping at all, that and the Auroral stuff. There was a weak banded arc of Blue/Green to the North but way less intense than the previous days -
