Thanks to neighbor N6TA, I've been able to measure the occupied 
bandwidth of the Yaesu FTDX5000 before and after implementation of 
Yaesu's September 2014 firmware upgrade. The results of the upgrade are 
quite positive -- the original FTDX5000 tested by ARRL Labs was pretty 
awful, close to the worst of all modern rigs. My measurements are 
documented in the link below. If you own one of these rigs, you owe it 
to your neighbors to do the upgrade. It's still nowhere near as clean as 
a K3, but it's a lot less awful. :)


73, Jim K9YC
