Part One of this series on NVIS operation focused primarily on the basics of NVIS; what it is, why it is, how it works, and listed some of the major factors involved in successful NVIS operation, briefly touching on these factors. Link here: https://www.americanpartisan.org/2021/05/nvis-techniques-part-one

Part Two of this series on NVIS operation looked at HF listening and transmitting techniques, some specific to NVIS. Link here: https://www.americanpartisan.org/2021/05/nvis-techniques-part-2

Part Three discussed how to decide which HF radio to purchase. Several common civilian amateur radios will be reviewed in some detail, and general characteristics desirable in an NVIS station specifically was discussed. Link here: https://www.americanpartisan.org/2021/05/nvis-techniques-part-3/

Part Four reviewed NVIS antenna characteristics in detail, and discussed different types of operation and a brief discussion of the implications of these differences on antenna sɛƖɛctıon.  Link here: https://www.americanpartisan.org/2021/06/nvis-techniques-part-4/

Part  4 1/2, was an amplification and further discussion of simple NVIS antennas in more detail, including the effects of height on antenna performance in response to questions.  Link here: https://www.americanpartisan.org/2021/07/nvis-techniques-part-4-1-2/

Part 5 is a discussion of advanced NVIS antennas  primarily for fixed locations and beginning to touch on NVIS operation in non-permissive environments. https://www.americanpartisan.org/2021/08/nvis-techniques-part-5/

Good articles. HF also happens to be a solid way for long range for packet communications, which in a grid-down situation or other times can be used to share files (bandwidth is pitiful compared to VHF/UHF of course though). 

To anybody not into this essential life skill... Understanding radio theory and getting a license (or just study the material if you are worried, which is reasonable) pretty much teaches you basic electronics too.

“…. I will re-iterate that these skills, along with Land Navigation, are among the most perishable and most difficult to learn- under duress, near impossible. So for those of you who feel you’ll do it when ‘the time comes’, you’ll be sadly mistaken.  Please folks, try this at home.”

One of the article's opening lines. So true. Too many think they will do without a license, then open the box and magically communicate. Nope. Need practice, especially with HF.

I'd say QRP is really the ultimate field test, if you can communicate with low wattage in HF you are golden. It's far different than putting a 100W mobile VHF rig in your car and hitting repeaters in town. I don't think VHF/UHF reward operator skill such as antenna design nearly as much, almost anyone can use a set of GMRS HTs, for example.
