: [Elecraft] K2, LP-100 and HRD etc

Neat,

So will it be possible to do one scan with a 50ohm load terminating the
cable, then do it again with the antenna connected, "subtract" the plots and
end up with the antenna characteristics?

The LP-100 Plot software does this already if you use DXlabs Commander 
(freeware) or TRX-Manager. It doesn't matter what rig is selected, it 
will work with any supported rig. You set the start and stop frequencies 
and step size, then hit Run. The program controls the rig and gathers 
the data. You can select the parameters to plot either before or after 
running, and save the plots to a file in CSV format for later recall or 
export to a spreadsheet.

It may be possible to add HRD, but I don't see a linking component for 
them that accepts all the incoming commands needed.

You can see a screen capture of the LP-100 Plot software at 
www.telepostinc.com/lp100.html, along with a comparison to a couple of 
antenna analyzers I own as well as my HP87510A VNA.
