[GreenKeys] HAL literature on line

[Paul Birkel]

For late joiners, these are now found in:  http://www.navy-radio.com/rtty/hal/misc/

 

Those are some really good-n-clear articles, including the FAQ in the middle of the catalog.  Highly recommended (at least by me).

 

Thank you for making these available to a wider audience.
