12m Hots up!

A busy day on 12m yesterday, as good transatlantic Es provided a lot of stations to work.

This was rather useful, as for one week, I'm operating as GB9BLM (Black Lives Matter).  So delivering the message directly into the US was great!

Signals kept coming in on 12 and 10m from north and central America until at least 01:35UT.

This morning, by 09UT, propagation for my signal to the east coast US was already strong, in some cases reaching 0 to +2dB SNR territory:

I then had a quick look at one of the FT8 signals coming across from the US, using my 3-ele LFA to listen to the variation in propagation using Argo.

It's very interesting to visually plot the ups and downs, which occur over very short timescales of just a few seconds.  Indeed, one of the propagation people at the RSGB was in contact with me about high resolution propagation studies like this just a few months ago, so there's still plenty to do to develop this idea, regardless of band of interest.  Again, hat tip to John, EI7GL, for prompting these thoughts.
