Hi K3 users, sorry for the first mail in HTML-format ASCII should fit better ;-)) what is your recommendation for the use of full-bk? I find it being not as smooth as I remember it from my old K2 What can I optimize? Does it help to switch off DSP functions like AFX, CWT or NR??? -- /*73 de*/ /*Wolfgang DK9VZ*/ ws at dk9vz.com <mailto:ws at dk9vz.com>
