[Elecraft] [K3] Diversity Reception and Antenna Directivity

[Kok Chen]

I just rummaged around in Google and found a different paper that  
Watterson wrote related to HF propagation and digital modes (almost 10  
years after his HF channel model paper):

http://www.its.bldrdoc.gov/pub/ntia-rpt/79-29/79-29.pdf

His conclusion definitely advocates the use of diversity reception.

Discussion of HF Channel model starts on page 35 (yes, gigantic  
manuscript), discussion on using separate receiving antennas on page  
46, use of matched filters on page 51, diversity reception on page 72.
