Hi Art, 


Well designed radios will not have a problem with 6 msec rise times using 
the highest CW speeds in use by contesters. 


YMMV with radios with design inadequacies.

Hi Frank, 


Would a 6 millisecond rise time affect the ability to hear between code 
elements in QSK at speeds in the mid 30 wpm.

Hi Tad, 


I don't know the specific answer to your question, it depends on the 
details of the IC-7610 design. 


The October 2018 QST product review discusses the IC-7610 4 msec 
keying rise time and the possibility that the 6 msec menue s election 
may be a better choice. 


In any case, 6 milliseconds should make you a better citizen than 4 msec.

Frank, my IC-7610 has 6 and 8 millisecond options as well. Is there any 
disadvantage to using 8 ms? 

Best regards,

That's an excellent step forward Bud. There's no excuse for intentional 
key clicks but that's exactly the place where the Japanese manufacturers 
have intentionally put us in 2020. 


The current generation of Japanese transceivers are making key click 
problems much worse than before. Our only hope is that contest 
sponsors improve their rules and enforce them against contesters 
taking advantage of the fast CW rise time menu options in their radios. 


Manufacturers are completely irresponsible with their 4 millisecond 
default CW rise times and egregiously irresponsible with menus 
options that allow users to select 1 and 2 millisecond rise times. 




Kenwood and Yaesu provide completely unacceptable 1 and 2 
millisecond rise time menu options and Icom is almost as bad with 
their 2 millisecond menu option. 


Why are ARRL and the U.S. distributors not communicating with our 
Japanese equipment manufacturers about the problems they're causing 
and enabling?

I have received two (2) actionable complaints of signal quality issues 
during WPX CW, which are both under review. 



We will investigate additional signal quality concerns. Please provide the 
call to be reviewed, along with the date, time and band of the observed 
signal quality issue.
