The solar flare on Jan 18, 18 h UT had an exceptionally-strong X1.9 x-ray burst, and also intense HF/VHF emission lasting about 1.25 hour. I've attached a few dynamic spectra of the whole of the rf emission and a couple of parts. There are several radio burst types mixed together.

I uploaded an example two-axis file here, and a larger three-axis file of part of the Jan 18 emission here. I don't have the internet capacity to move large volumes of data.
