Hello Henk,

One of the nice things I enjoy about my K3 on JT65 modes is that I have 
a relatively flat bandpass response over an entire 4 KHz for when I am 
in the USB position with my 6 KHz wide roofing filter.  This makes it 
possible to utilize the full ability available in the program to decode 
signals in that passband without changing frequency. It is great for 
pileups, where the callers can spread out to avoid QRMing each other.  
The bandpass shaping of my old receiver was not nearly that broad.

I am sure you will enjoy using your K3 on EME.  GL and VY 73, Lance
