Hi edr1924,

in the software of the TX module main tab beginning from line 100 you can find the different impulse <-> wind speed correlations of the different devices. Depending on which anemometer you want to emulate you can calculate a output frequency corresponding to your actual wind speed.

Best regards,

Thanks, yes I have to go that route, changing the WD software itself. 
I was hoping to make a Davis 6410 compatible 'plugin' converter but alas...
