This is one of our most interesting contests. If you have never tried these different PSK modes, don't be shy. 


There has been lots of discussion on the Reflectors concerning how to set up MACROS to change modes efficiently. Check it out.


Last year, we had 45 Logs submitted, which is the highest since 2016. Lee, N5SLY, won Top Dawg honors and First Place in the 50W category with a spectacular 92 QSOs utilizing all 6 modes.


Let’s see if we can give Lee some competition this year ! 

Hope to work you in all 6 modes!
