I'm doing some research and digging for data about the recent thread associated 
with the effect FTx has had on traditional weak signal modes (ssb/cw). 

In the process I noticed a dramatic decrease in both Limited Multi and 
Unlimited Multi activity and scores (September VHF Contests) in the mid-late 
2000's and again in 2015. The authors of the results write-ups noted this as 
well but didn't offer an explanation (unless I missed it). 

Why??? What am I missing? FT8 didn't begin till 2017 (according to that 
write-up). Remember, I only looked at the September results! 2015 was the first 
year allowing use of spotting in all categories (spots, chat rooms, email, 
text, phone, etc.).

See my chart below. I had a little difficulty getting all the #'s if it wasn't 
mentioned in the write-up - scanning and manually counting results - I may have 
missed a few either way, scores were rounded.

Thoughts?
